What is Fault Code P1124?
Fault code P1124 stands for "Throttle Position Sensor Outside Self-Test Range". This indicates that the throttle position sensor is outside its normal operating range. The sensor signals the throttle position to the vehicle's engine control unit (ECU). It is a critical component for ensuring the right air-fuel mixture and optimizing engine performance. The Fault code P1124 occurs because of the sensor producing abnormal values while testing itself or during normal operation.
Symptoms of Fault Code P1124
Symptoms of the P1124 Fault code can include several vehicle performance and driving issues caused by the sensor not working correctly:
Decrease in Engine Performance: When the accelerator pedal is pressed, the vehicle does not accelerate properly or reacts with a delay. The vehicle may show a sudden loss of power or an uneven acceleration during acceleration.
Fuel Consumption Issues: A faulty sensor can cause the engine to fail to adjust the fuel-air mixture correctly, leading to excessive fuel consumption.
Engine Fault Light (MIL): The engine control unit turns on the engine fault light when it detects a problem with the throttle position sensor.
Irregular Idling: When the vehicle is idling, fluctuations in engine speed may occur or the engine may stop (stall) suddenly at idle.
Problems with Accelerator Pedal Response: When the accelerator pedal is pressed, the vehicle does not react properly, either sudden accelerations or insufficient reaction may occur.
Exhaust Problems: When the throttle position is detected incorrectly, the air-fuel mixture can be disrupted, and the unburned fuel can come out of the exhaust as black smoke.
Problems with Transmission Behavior: Incorrect readings in the throttle position can disrupt the gearshift timing of the transmission.
Engine Can Go into Safety Mode: If the ECU detects a serious fault in the sensor, it can put the vehicle into safety mode to protect the engine.
Vibration and Vibration: Vibration may be felt in the vehicle due to unstable operation of the engine.
Exhaust Emission Problems: An incorrect air-fuel mixture can increase the vehicle's emission values and cause problems with exhaust inspection.
Causes of Fault Code P1124
There are many potential causes of the Fault code P1124:
Throttle Position Sensor (TPS) Malfunctions:
Wear of the sensor
Incorrect calibration
Physical damage
Electrical Problems:
Breakage or damage to the wiring harness
Connector problems
Low or high voltage
Throttle Mechanical Problems:
Throttle blockage
Mechanical wear
Jamming or erratic movement
Engine Control Unit (ECU) Problems:
Incorrect reading of the sensor by the ECU
ECU software problems
Incorrect Sensor Mounting:
Improper placement
Incompatible part
Other Related Sensor or System Issues:
Accelerator pedal sensor (APP) problems
Broken transmission control module (TCM)
Defective air flow sensor (MAF)
Operating and Usage Conditions of the Vehicle:
Extreme temperature or humidity
Improper care
How to Fix P1124 Fault Code
The following steps can be followed to fix the Fault code P1124:
Verifying the Fault Code with the OBD-II Scanning Device: Verify the Fault code P1124 and other related Fault codes using an OBD-II scanner.
Checking the Throttle Position Sensor: Visually inspect the sensor and check for physical damage.
Electrical Control of the Throttle Position Sensor: Check the voltage of the TPS with a multimeter.
Replacing the Throttle Position Sensor: If you detect physical damage or wear, replace the sensor.
Check the Transmission and Engine Control Module (ECU): Check if the ECU is working correctly and make sure that the transmission control module is working properly.
Throttle Cleaning: If the throttle valve is contaminated, clean it.
Transmission Fluid and Engine Condition Check: Check the transmission fluid level and make sure the engine is working properly.
Resetting Electronic Systems: Clear the Fault code and restart the engine. If the tool is working properly, then the problem is resolved.
Long-Term Effects of Fault Code P1124
The Fault code P1124 can have serious effects on your vehicle's performance, fuel efficiency, emission levels, and safety. Malfunctions in the throttle position sensor can adversely affect the efficiency and driving comfort of the vehicle. Therefore, early detection and repair of this Fault code is beneficial for both the car owner and the environment overall.
