If the problem persists, it would be best to seek help from a specialized technician, as there may be a more complex problem with the vehicle's electronic systems.   Significance of Error Code P1123   Here are some key points that explain why error code P1123 is important:   1. Engine Performance and Acceleration Issues   Acceleration Delay:  The throttle position sensor determines the engine's relationship with the accelerator pedal. When the TPS is faulty, it becomes difficult for the engine to get the right amount of fuel-air mixture. This can cause a delay in acceleration or an erratic response.   Power Loss:  A faulty sensor prevents the engine from working as it should, and the vehicle does not move with the expected power, which can lead to problems while driving.   2. Fuel Efficiency   High Fuel Consumption: Erroneous data from the throttle position sensor causes the engine to fail to adjust the air-fuel mixture correctly. This, in turn, leads to excessive fuel consumption because the engine runs inefficiently.   Emission Issues:  This type of breakdown can also negatively affect vehicle emissions. When the engine is not running efficiently, more dirty gases can come out of the exhaust, which negatively affects the environment.   3. Transmission and Gear Change Problems   Irregular Gear Changes:  TPS helps the transmission shift correctly with engine speed and throttle position. When this sensor is faulty, the transmission may not shift properly, which affects driving comfort and safety.   Driving Safety: Incorrect throttle data can disrupt the synchronization between the transmission and the engine, causing sudden acceleration and deceleration problems. This can be dangerous, especially when driving in traffic.   4. Engine Fault Lamp Lights Up   Engine Warning Light:  The error code P1123 usually notifies the engine control unit (ECU) that there is a problem. When the ECU misinterprets the data provided by the throttle position sensor, it turns on the engine fault lamp. This light alerts the driver to be aware of the problem immediately and ensures early intervention.   More Serious Problems: If the P1123 error code is ignored, a small problem can turn into a larger malfunction over time. This, in turn, can lead to costly repairs.   5. Driving Comfort and Risk of Failure   Erratic Engine Operation:  Erroneous data from the throttle sensor can lead to the engine not working properly and fluctuations in idle. This causes the vehicle to run unsteadily while driving and reduces driving comfort.   Vehicle Stalling:  This error can cause the vehicle to stop suddenly while idling. This creates a significant safety risk, especially in heavy traffic or at low speed.   6. Emission Control and Exhaust Issues   Failure in Emission Tests: A faulty TPS incorrectly regulates the air-fuel mixture, which can lead to vehicle failure in emissions tests. This, in turn, harms the environment and can prevent the vehicle from being legally on the road.   High Smoke from the Exhaust:  An irregular air-fuel mixture can lead to black smoke coming out of the exhaust, which has negative effects on the environment and can negatively affect the vehicle's exhaust system.   7. Security Risks   Torque and Power Issues:  Failure of the throttle position sensor prevents the engine from properly controlling torque and power delivery. This can lead to loss of control of the vehicle, especially at high speed or during sudden maneuvers.   Sudden Power Loss:  This sensor failure can cause the motor to lose power in an instant. This can cause the driver to lose speed unexpectedly, causing traffic accidents.

What is throttle position sensor (TP) (TPS) (Throttle Position)? The throttle position sensor (TPS), also known as the TP (Throttle Position) sensor, is a sensor that detects the position of the throttle in motor vehicles. The throttle is a valve that controls the engine's air intake and increases or decreases the engine's air flow when the accelerator pedal is pressed.   TPS detects whether the throttle is open or closed and sends this information to the engine control unit (ECU). Using this information, the ECU adjusts fuel injection and ignition timing, thus optimizing the performance and efficiency of the engine.   The TPS is usually mounted on the throttle and is usually a potentiometer type sensor. As the accelerator pedal is turned or pressed, the output voltage of the sensor changes and this change is detected by the ECU. Throttle position sensor (TPS)   How Does Throttle Position Sensor (TPS) Work?   The operating principle of the throttle position sensor (TPS) is simple: as the throttle is opened or closed, the position information detected by the sensor changes. Here's a more detailed explanation of how TPS works: Physical Location: The TPS is usually attached to the throttle shaft or mechanism. As the throttle is opened or closed, the TPS physically moves.   Potentiometer Principle: TPS is generally a potentiometer type sensor. The potentiometer provides the voltage received from a certain point of a resistor element with a changing resistance. As the throttle is opened or closed, the sensor's potentiometer rotates and the resistance changes.   Voltage Output: The output of the TPS is a voltage signal that changes due to changing resistance in the potentiometer of the sensor. Generally, when the throttle is closed, the voltage produced by the TPS is close to zero, while when the throttle is fully opened, the voltage produced by the TPS approaches the maximum value. Information Sending to ECU: The voltage signal produced by the TPS is detected by the engine control unit (ECU) or engine brain. Using this information provided by the TPS, the ECU adjusts the engine's air-fuel mixture and other parameters.   Fuel and Ignition Tuning: The ECU adjusts fuel injection and ignition timing using the throttle position detected by the TPS. For example, when the throttle is fully opened, the ECU can inject more fuel and provide more ignition timing, thus increasing the power output of the engine. What Components Is The Throttle Position Sensor (TPS) Connected To?   The throttle position sensor (TPS) is connected to the following components.   Throttle: The TPS is physically mounted on the throttle and is connected to the throttle shaft or mechanism. As the throttle is opened or closed, the position information detected by the TPS changes.   Engine Control Unit (ECU): The TPS is connected to the engine control unit or engine ECU. The voltage signal generated by the TPS is detected by the ECU and used to adjust the engine's air-fuel mixture, ignition timing and other parameters.   Electrical Connections: The TPS is connected to the vehicle's electrical system. Usually, the TPS's connections are part of the vehicle's wiring harness and communicate with the electrical systems in the vehicle. These connections are used to transmit the voltage signal generated by the TPS to the ECU.   Other Engine Sensors and Systems: The information provided by the TPS also interacts with other engine sensors and systems. For example, the information generated by TPS can also have an impact on systems such as the vehicle's gear changes, traction control systems and cruise control.   What kind of faults does the throttle position sensor (TPS) have?   Here are common faults with the Throttle Position Sensor (TPS):   Deformed Sensor Mechanism: The TPS has a mechanism that physically moves as the throttle opens and closes. This mechanism can become deformed or worn over time, preventing the sensor from working properly. Pollution or Dirt: The sensor may become clogged or dirty due to pollution or dirt in the engine compartment. This may prevent the sensor from working properly or distort the sensor signal.   Cable or Connection Problems: Cables or connections to the TPS may become loose, broken, or corroded. This may prevent the sensor from sending the correct signal.   Damage to the Sensor: The TPS itself can be physically damaged. For example, its potentiometer may be broken or its internal circuits may be faulty.   Calibration Problems: The calibration of the TPS may be corrupted. In this case, the sensor cannot accurately detect the throttle position, which sends incorrect information to the engine control unit (ECU). Electrical Faults: A fault in the TPS's circuitry may prevent the sensor from functioning properly. This could be open circuits, short circuits, or other electrical problems.   These malfunctions can prevent the TPS from working properly and cause problems with the vehicle's performance. Therefore, it is important to check the TPS regularly and perform maintenance or repairs as necessary.   How to Test Throttle Position Sensor (TPS)?   You can follow the steps below to check whether the throttle position sensor (TPS) is working correctly:   Fault Code Check: First, read any fault codes from the vehicle. Error codes may indicate that there may be a problem with the TPS. You can check existing fault codes on the vehicle using an OBD-II scanner.   Physical Examination: Check the physical condition of the TPS. Visually check ports and cables. Detect corrosion, broken or loose connections. Clean or tighten connections if necessary.   Measurement of TPS: Measure the resistance value of TPS using a multimeter. The TPS is a potentiometer type sensor, so check for an open circuit, short circuit, or resistance value outside the correct values. Compare with the values specified by the manufacturer.   Real-Time Testing of TPS: Monitor real-time values of TPS using an automotive diagnostic scanner or data monitoring device. Observe how the TPS values change when pressing and releasing the accelerator pedal or when the engine is running. Make sure the values change smoothly and match the throttle movement.   Throttle Control: Control how the TPS's output voltage changes by manually opening and closing the throttle. Make sure the values match the throttle movement. Calibration Check: Check if the TPS is calibrated correctly. On some vehicles the TPS may need to be recalibrated. Follow the procedures specified by the manufacturer.   Connection and Cable Check: Check the cables and connections to the TPS. Check for cable breaks, breaks or corrosion. Replace cables or repair connections if necessary.   By following these steps, you can check if the TPS is working properly and perform maintenance or repairs if necessary. However, if you think the TPS is faulty and you are having difficulty repairing it, it is important to consult a car service or a specialist technician.

These steps are important to correctly identify and resolve the source of the problem in the system.   First Step: Use an OBD-II scanner to verify the error code. This device can provide more information by reading the P0257 error and other possible related error codes.   Extra Codes: If other fault codes are present, the combined effect of these codes may help identify the source of the problem. Check Valve and Sensor Connections: Check that the wiring connections for the injection pump and fuel metering control valve are secure. If there is oxidation, loose connections, or frayed wires on the connections, they should be repaired.   Checking the Sockets: Remove and clean the electrical connection sockets. If there is corrosion, clean and re-install.   Pump Inspection: Inspect the internal components of the injection pump (camshaft, rotor). Inspect these components for wear, contamination or blockage.   Fuel Metering Valve: Check the fuel metering valve for proper operation. Since the valve is an electronically controlled part, proper mechanical operation as well as electrical connections are required. If the valve is excessively worn or clogged, it may need to be replaced.   Fuel Pressure Test: Perform pressure tests on the fuel system to check for any leaks or pressure loss in the injection pump and fuel line. If the pressure is low, there may be a blockage in the pump or filter. Low pressure may result in the fuel not reaching the correct amount to the injection system.   Fuel Filter: A clogged or dirty fuel filter can prevent fuel from being pumped properly. Clean or replace the filter.   Fuel Line: Check the fuel line for any leaks or leaks. Leaks can cause a pressure drop and an improperly functioning fuel system.   Pressure Sensors: Test the injection pump pressure and valve position sensors for proper operation. Faulty sensors can produce false readings, which can send incorrect information to the engine control module (ECM), preventing it from functioning properly.   ECM Software Update: If the engine control module (ECM) software is out of date, a software update can be performed. Old software may incorrectly control injection system components.   ECM Test: Check if the ECM is functioning properly. If the ECM is faulty, it may need to be repaired or replaced.   Check if the problem is solved: Once the above steps are completed, take the car for a test drive. Observe the engine performance and check if the error code reoccurs.   Test for Proper Operation: Check to see if the engine is operating properly. If the engine is still not operating properly, there may be another issue and the problem may need to be investigated further.   Long Term Effects   Long-term effects of fault code P0257:   Loss of Power and Acceleration Problems: When the injection pump and fuel metering valve are not working properly, the engine cannot produce enough power. This is especially noticeable during acceleration and reduces the performance of the vehicle.   Irregular Operation and Vibrations: The engine may run irregularly during idling, vibrations and shaking may be felt. This can significantly reduce driving comfort in the long term.   P0257 Inefficient Combustion: When the fuel metering control is not working properly, the engine may take in too much fuel. This will result in the fuel not being burned at full efficiency and will cause unnecessary excess fuel consumption.   Failure to Start: If problems with the fuel injection pump and valve get worse over time, the engine may become difficult to start or may not start at all. This is one of the most serious problems with a vehicle and can cause the engine to stop completely.   Slow Response and Hard Starting: A hard starting engine makes the vehicle difficult to use and causes difficulties every time the engine is started.   Increased Carbon Emissions: Improper combustion of fuel can increase carbon emissions from the exhaust. This negatively impacts the environment and can cause the vehicle to fail emissions tests. Damage to the Exhaust System: Inefficient fuel combustion can lead to carbon buildup in the exhaust system, causing damage to components such as oxygen sensors and catalytic converters.   Wear on the pump and injectors: Malfunctions in the injection pump or fuel metering valve can also damage other components of the injection system. In the long term, wear on the pump and injectors can lead to more serious malfunctions.   A dirty or clogged injection system can prevent the engine from operating efficiently and lead to more expensive repairs.   Overload: Problems in the injection system feed the engine with too much fuel, which leads to overheating and wear of the internal parts (pistons, rings, cylinders, etc.).   Contamination of Engine Oil: Excessive fuel mixes with engine oil, reducing its efficiency. This can cause accelerated engine wear and serious mechanical failure.   Therefore, when encountering the P0257 error code, resolving the problem as soon as possible ensures the longevity of the vehicle and avoids high costs.

What is the P0258 Error Code?   The P0258 Error code is a fault code that indicates poor performance or value in the fuel injection pump fuel metering control circuit B. This code indicates that there is a problem with the engine's fuel injection system, specifically a fault in the cam, rotor or injector components. This type of fault can prevent the engine from running properly, make it difficult to inject fuel efficiently and negatively affect the engine's performance.   Injection Pump Fuel Metering Control B: This is the part of the system that ensures that the injection pump injects the correct amount of fuel at the correct timing. The letter "B" usually refers to a second circuit or component of the system. This component is important for the correct metering and pumping of fuel.   Low Value: The P0258 trouble code indicates that the fuel injection pump or fuel metering sensor is performing below expected levels. This could be due to low pressure, low flow, or low voltage from the sensors. The injection pump, cam and rotor components must operate at a certain pressure and speed to accurately inject fuel into the engine cylinders. If these parameters are low, the engine will not operate efficiently.   Cam, Rotor, Injector: Cam and Rotor: The mechanical parts in the fuel injection pump work together to pump the right amount of fuel at the right timing. Misalignment or wear between the cam and rotor can cause the system to operate inefficiently. Injector: Injectors are important components that inject fuel into each cylinder of the engine. If the injectors become clogged or malfunction, the fuel may not reach the engine cylinders properly, causing the engine to run inefficiently.   Symptoms   Common symptoms of error code P0258:   Decrease in Engine Performance: The vehicle engine may lose power.

What is the P0628 Fault-error Code?   The P0628 fault-error code is detected by your vehicle's OBD-II diagnostic system as an indication of a problem with the fuel pump control circuit. Specifically, this code refers to a "Fuel Pump A Control Circuit Low" error. This indicates that the voltage required for the fuel pump to operate properly is lower than it should be.   Fuel Pump A: A circuit that controls the fuel pump in your vehicle, or a system that communicates with the engine control unit (ECU). Control Circuit Low: The electrical voltage required for the fuel pump to operate is not at a sufficient level or the circuit is not closing completely.   Symptoms   Common symptoms that can cause a P0628 error code on a vehicle include:   Engine Performance Problems: The vehicle may be difficult to start or may not start at all (the engine will not start at all). The idle may fluctuate or hesitate. The vehicle may lose power during acceleration.   Fuel Pressure Problems: Due to low fuel pressure, the engine cannot be supplied with fuel properly. Fuel economy may decrease because the engine cannot perform proper combustion.   Check Engine Light on Dashboard: The Check Engine light or engine fault warning light comes on. This means that code P0628 can be determined by the diagnostic device.   Unusual Noises: You may hear strange noises from the fuel pump (for example, a growling noise or a continuous straining sound when trying to start).   Engine Stalling: The vehicle may suddenly stall while driving or idling.   Temporary Starting and Stopping Problems: Once the vehicle is started, it may run properly for a while, but the engine may stop shortly after.   Loss of Power: The vehicle may lose power due to fuel supply problems, especially when climbing hills or at high speeds.   Reasons   Possible causes of error code P0628:   Fuel Pump Relay or Fuse Failure: The relay or fuse used to operate the fuel pump may have failed. A blown fuse or a faulty relay will cause an interruption in the circuit and the pump will not run.   Fuel Pump Failure: The fuel pump motor may be broken or not drawing enough electrical current to operate. This prevents the pump from sending fuel to the engine at sufficient pressure.   Electrical Connection Problems: There may be a break or interruption, loose connections, corrosion or oxidation in the electrical cables going to the fuel pump. Short circuits or grounding problems can also cause this error.   ECU (Engine Control Unit) Problem: The engine control unit (ECU) may not be operating the fuel pump control circuit properly. If there is a problem with the programming or internal hardware of the ECU, it will not be sending the correct signal to the fuel pump.   Low Battery Voltage or Alternator Problems: When the battery voltage is low, the fuel pump cannot provide the energy it needs to function properly. When the alternator is not producing enough voltage, this can cause this error.   Fuel Pump Control Module Failure: The fuel pump control module is a component used to regulate voltage and operate the pump. If the module fails, the pump may not work or a low voltage problem may occur.   Water or Moisture Ingress: If water/moisture enters the fuel pump relay, wiring harness or connection points, the circuit may short or increase resistance.   Sensor Issues: Some vehicles have pressure sensors built into the fuel pump system. A sensor failure can cause the system to operate incorrectly.   Rare Causes Using the wrong fuel: Using a fuel other than the recommended fuel for the fuel system may cause problems. Faulty Repair or Replacement: Using the wrong parts or breaking the wiring during a previous repair.   To resolve the issue, a detailed check is recommended: Check fuel pump relay and fuse. Examine the wiring and connections. Test the operation of the fuel pump and control module. Assess whether the ECU is faulty. Check the battery and charging system.   How to Fix   To resolve the P0628 error code, you can follow the steps below. This process is necessary to identify the source of the problem and fix it correctly.   Reset and Test Error Code: Read and reset error code with OBD-II device. Restart the vehicle to see if the problem is a temporary electrical fault.   Check Fuel Pump Relay and Fuse: Check the fuse: If the fuel pump fuse is blown, replace it. Test the relay: If the relay is not working properly, replace it with a new relay. Check the relay and fuse box for corrosion or loose connections.   Test the Fuel Pump Perform an electrical test: Measure the voltage to the fuel pump with a multimeter.

You should take this error code seriously and have the necessary checks performed to avoid long-term effects of the problem.

What is the P0327 Fault-Error Code?   The P0327 fault-error code indicates a problem detected by the vehicle's Engine Control Module (ECU). This error indicates that the signal from the knock sensor is too low or not detected at all. The knock sensor sends information to the ECU by detecting knocks (abnormal combustion events) that may occur during engine operation. This information is used to optimize engine timing and prevent knocking problems. Symptoms   Most common symptoms associated with error code P0327   Decreased Engine Performance: Since the ECU (Engine Control Unit) does not detect knocking, it safely rolls back the engine timing. This results in engine power loss and poor performance is noticeable during acceleration.   Increase in Fuel Consumption: Fuel economy may decrease because the combustion process is not optimized. The vehicle can operate by consuming more fuel.   Check Engine Light Comes On: The Check Engine light may come on, indicating a problem with the vehicle.   Abnormal Sounds (Knocking or Rattling Noises): Knocking noises inside the engine can be heard. This could be a sign of abnormal combustion or mechanical problems inside the engine. However, the ECU may not detect it because the knock sensor is not generating a signal. Hard to Start or Stall: In some cases, the engine may become hard to start or idle erratically.   Increase in Exhaust Emissions: When the combustion process does not occur properly, the vehicle may emit more harmful gases.   Increased Engine Vibrations: If the combustion timing is disrupted, the engine may run erratically and you may feel more vibration.   Reasons   Here are the most common causes of error code P0327:   Knock Sensor Failure: The knock sensor may be damaged or malfunctioning. The sensor may not be detecting engine vibrations properly or may not be sending a signal at all.   Wiring and Electrical Connection Problems: There may be a break or loose connection in the cables going to the knock sensor. A short circuit or poor contact may occur. The connectors may be oxidized, damaged or dislodged.   Improper Sensor Installation: Installing the knock sensor with the wrong torque may result in improper contact with the engine block. Also, if the sensor is not mounted correctly, it may not be able to detect engine vibrations.   Engine Control Unit (ECU) Issues: There may be a software or hardware failure in the ECU's processing of the signals from the knock sensor. The ECU may need to be updated or reprogrammed.   Low Signal Voltage: The signal from the knock sensor to the ECU may be weak. This is usually caused by an internal sensor failure or wiring issue.   Physical Damage: The knock sensor may have been damaged or impacted during engine operation. Also, excessive engine vibration or erratic operation may damage the sensor.   Actual Engine Problems: Abnormal vibrations or knocking (combustion problems) in the combustion chamber inside the engine can make it difficult for the sensor to detect normally. Engine wear, valve problems, or issues with ignition timing can contribute to this condition.   Battery or Voltage Issues: Low battery voltage or a general problem with the electrical system can affect the proper operation of the knock sensor. Use of Aftermarket or Incompatible Parts: Replacing the knock sensor with an incompatible spare part instead of the original equipment may cause signal incompatibility.   How to Fix   Here are the steps that can be taken to resolve the P0327 Error Code:   Verify Trouble Code: Verify code P0327 by connecting the vehicle to an OBD-II diagnostic device. Check the knock sensor signals from the live data stream on the diagnostic device.   Visually Inspect the Knock Sensor: Examine the physical condition of the sensor: Is there any cracking, breaking, or other physical damage? Is the mounting loose or the sensor dislodged? Make sure the sensor is properly mounted to the engine block.   Check Wiring and Connections: Check wiring for breaks, loose connections, shorts or corrosion. Make sure sensor connector is clean and secure: Clean any oxidation on connectors. Tighten loose connections.   Test the Sensor's Signal: Measure the signal from the knock sensor using a multimeter or oscilloscope: Does the sensor respond to vibrations while the engine is running? Does it produce an output within the expected signal range (usually 0.5V- 4.5V)? If the sensor does not produce a signal or the signal is weak, the sensor should be replaced. Ensure Proper Torque Mounting of Sensor: Make sure the knock sensor is mounted with the correct torque. Manufacturer torque values typically range from 15-25 Nm. Incorrect torque can prevent the sensor from properly detecting engine vibrations.   ECU Update or Reset: A software update may be required to ensure the ECU is communicating correctly with the sensor. Reset the ECU to check if this resolves the issue and see if the code reoccurs.   Check Engine Vibrations and Mechanical Problems: Excessive engine block vibrations can affect the operation of the knock sensor. Check the engine's mechanical systems such as ignition timing, fuel mixture, or valve adjustments.   Sensor Replacement: If the sensor is proven to be faulty, replace it with an original equipment (OEM) standard knock sensor. Avoid aftermarket products as they may cause signal incompatibility. Battery and Voltage Checks: Low battery voltage or electrical system problems may prevent the sensor from working properly. Test the battery and charging system.   Take a Test Drive: Once the problem is resolved, take the vehicle for a test drive to check if the ECU is receiving the correct signal from the knock sensor.   It is recommended that you seek help from an auto electrical or mechanical professional.   Long Term Effects   Long-term effects that may occur if the P0327 Trouble Code is not resolved:   Permanent Decrease in Engine Performance: A faulty knock sensor will prevent the ECU from setting the engine timing correctly. The ECU will go into a safety mode and pull the engine timing back more "cautiously". This will cause the vehicle to produce low power and lack acceleration.   Increased Fuel Consumption: Lack of knock detection means that the combustion process cannot be optimized. As a result, the vehicle consumes more fuel and fuel economy can be permanently impaired.   P0327 Emission Problems: Problems in engine timing cause incomplete combustion and increase harmful gas emissions.   Engine Wear and Damage: A faulty knock sensor prevents the ECU from detecting knock events (abnormal vibrations in the combustion chamber) within the engine. If knocking continues for a long time without being detected, it can cause serious damage to the combustion chamber, pistons, rings and cylinder walls. This can significantly shorten the life of the engine.   Damage to ECU and Other Systems: Incorrect signals from a faulty knock sensor can make it difficult for the ECU to manage other systems. Since the ECU is constantly working with incorrect data, there is an increased risk of damaging other electronic components in the long run. High Repair and Maintenance Costs: If the problem is not resolved in time, damage to the mechanical components inside the engine may increase repair costs. For example, piston damage, valve failures or engine rebuilds can be very costly. Safety Issues: A decrease in engine performance can endanger driving safety, especially in situations requiring high power, such as overtaking or climbing a hill. The vehicle may experience a sudden loss of power or may not accelerate properly.   The P0327 error code should not be ignored in the long term. Early diagnosis and resolution of the problem will prevent costly repairs by ensuring the engine operates efficiently and safely. Therefore, it is important to consult an auto repair professional when the problem is noticed.

What is the P0329 fault-error Code?   The P0329 fault-error code indicates a problem detected by your vehicle's Engine Control Module (ECU). This error indicates an intermittent (intermittent) connection or signal error in the signal from the knock sensor (commonly known as the "knock sensor"). This means that the sensor is not working properly, is not transmitting the signal correctly, or has a faulty connection. The knock sensor detects abnormal combustion events (knocks) during engine operation and sends a signal to the engine's ECU. The ECU adjusts the engine's ignition timing according to these signals, ensuring the engine operates efficiently. If the knock sensor is faulty, the engine's combustion process cannot be properly controlled, which can negatively affect the engine's performance and efficiency.   Symptoms   Below you can find the most common symptoms associated with this error code:   Decreased Engine Performance: Since the ECU (Engine Control Unit) does not detect knocking, it safely rolls back the engine timing.
