What is P0655 Error-Fault Code?
The P0655 Error-fault code is an OBD-II (On-Board Diagnostics II) error code that indicates a fault in the vehicle's engine temperature lamp output circuit. This error code typically indicates a problem with a sensor or circuit used to determine and report the vehicle's engine temperature to the driver. The error code does not provide a specific diagnosis. It can indicate a wide range of possible problems with many components and circuits in your vehicle.
Causes of P0655 Error/Fault code:
There are several possible causes for the P0655 Trouble/Error code:
Engine Temperature Sensor Failure: The engine temperature sensor is a sensor that measures the temperature of the engine. This sensor may be faulty or not working properly.
Problems in Sensor Connections: Electrical connection problems such as looseness, oxidation or damage may occur in the connections related to the engine temperature sensor.
Sensor Wiring Problems: Problems in the wiring between the sensor and the engine control unit can trigger this error code.
Engine Temperature Light or Circuit Malfunctions: A malfunction in the engine temperature light or its circuit may trigger the error code.
Electrical Issues: Generally, an issue with the vehicle’s electrical system can cause these types of error codes. This can often include poor grounding, shorts, or cut wires.
Symptoms of Fault/Error code P0655:
Symptoms of the P0655 Trouble/Error code may include:
Engine Temperature Gauge Problems: The engine temperature gauge may behave differently than normal. For example, it may show a lower temperature than normal or not work at all.
Engine Temperature Light Problems: If your vehicle uses an engine temperature light, problems such as the light not coming on or coming on incorrectly can occur.
Engine Intervention and Cooling Problems: Failure to obtain engine temperature information correctly can make it difficult to intervene in the cooling system. In this case, it may be difficult to cool or warm the engine properly.
Low Performance or Safety Mode: When the vehicle is unable to receive engine temperature information, it may go into some type of safety mode, usually to reduce performance and increase safety for safety reasons.
Engine Problems: If the engine is running without temperature information, the risk of engine overheating and damage may increase.
These symptoms can occur when encountering the P0655 error code. If you are experiencing this type of error code on your vehicle, it is important to contact a car dealer or authorized service center and have the problem diagnosed.
Correction of P0655 Error/Fault code:
To fix the P0655 Trouble/Error code, you can follow the steps below:
Check Sensor and Connections:
Check the engine temperature sensor and its connections. The connections may be loose, oxidized, or damaged. Clean or tighten the connections if necessary.
Check the Cable Connections:
Examine the wiring between the sensor and the engine control unit. Check for cuts, damage or oxidation in the wiring.
Replace the Sensor:
If the engine temperature sensor is faulty, replacing the sensor is usually the solution. By using a new sensor, you can get accurate temperature information.
Check the Electrical System:
In general, the vehicle's electrical system should be reviewed. Problems such as short circuits, cut wires or poor grounding can be detected and corrected.
Check the Dashboard:
If there is a problem with the engine temperature gauge or light, check the instrument cluster. If this is the source of the problem, the instrument cluster may need to be repaired or replaced.
Engine Control Unit (ECU) Test:
If other steps do not resolve the issue, check the status of the engine control unit (ECU). ECU testing can be a more involved process and should generally be performed by a professional mechanic.
These steps are general guidelines for resolving issues with the P0655 error code. However, these types of faults often require expertise and specialized diagnostic equipment, so contacting a car dealer or authorized service center is usually the best solution.
Importance of P0655 Error/Fault Code:
The significance of the P0655 Error/Fault code can be summarized as follows:
Engine Temperature Information:
The engine temperature sensor measures the temperature of a vehicle's engine. This information is important for the engine to operate efficiently and maintain proper temperature conditions. This information is also critical to other systems that affect engine performance, such as emission control systems and fuel injection.
Security and Performance:
Engine temperature information is important to ensure the safe operation of the vehicle. If engine temperature information is not obtained or is incorrect, problems such as decreased vehicle performance, overheating or cooling may occur.
Energy Efficiency:
Engine temperature information is used by fuel injection and other engine control systems to help operate the engine efficiently. Incorrect temperature information can have a negative impact on fuel consumption.
Emission Control:
Engine temperature information is used in modern vehicles to ensure compliance with emission standards. Incorrect temperature information can affect emission values and increase environmental impact.
Dashboard Information:
The engine temperature light or indicator informs the driver about the temperature status of the engine. This helps the driver to ensure safe operation of the vehicle. Incorrect information may mislead the driver and cause safety risks.
For these reasons, issues with the P0655 error code should be taken seriously and resolved as soon as possible. Engine temperature information is essential for the safe and efficient operation of the vehicle, and such an error condition can affect the performance and safety of the vehicle.
