P0A00 - OBD Trouble Code

<<See All OBD Codes

What does P0A00 error code refer to? What are its symptoms? Are you looking for this information? Then you are in the right place. This is a general type of error code which takes place in the motor electronics coolant temperature sensor circuit when the engine keeps overheating. If the powertrain control module (PCM) finds an erratic signal from the motor electronics coolant temperature sensor, then the P0A00 error code will be stored.

The temperature of the hybrid cooling system is monitored by the motor electronics coolant temperature sensor. The errors or malfunctions in the sensor are also identified by the power management control ECU that is engine control unit depending on the high voltage values of the coolant temperature sensor. The inverter along with the converter assembly identifies that error or faults in the high voltage coolant temperature sensor as well as its related wires.

What causes this problem with Motor Electronics Coolant Temperature Sensor Circuit?

• The motor electronics coolant temperature sensor is defective.
• There is an opening in the motor electronics coolant temperature sensor or the circuit is shorted.
• The electrical connection of the motor electronics coolant temperature sensor circuit might be weak.

1. Electronic Control Unit - Repairing the defective engine control unit can make your engine function normally.
2. Engine Coolant Temperature Sensor - Fixing the faulty engine coolant temperature sensor can help to avoid the P0A00 error code.
3. VCT Solenoid - The broken or damaged variable camshaft timing solenoid needs quick replacement to avoid P0A00 error code.
4. Cylinder Head Gasket - Check if the cylinder head gasket is broken or damaged? If so replace them as soon as possible.
5. Powertrain Control Module - The best idea to get rid of the P0A00 error code is to change the faulty powertrain control module
6. Engine Wires - Are the engine wires broken? Are you looking to replace the damaged wires? Get them from Parts Avatar at an affordable cost online.

It is essential to know the symptoms of an issue as only then you would be able to solve the problem. So that’s why we have listed out some major symptoms of OBD Code P0A00 here:

Common Symptoms

• You will notice that the warning light of the service engine or the engine lights remains on.
• Excessive engine heat.

Here are some ways with the help of which you will be able to correct the OBD Code P0A00.

• Fixing the damaged engine control unit.
• Coolant temperature sensor needs replacement.
• VCT solenoid has to be changed.
• Cylinder head gasket needs to be repaired
• The damaged powertrain control module must be altered.
• Engine wires must be checked for damages or corrosions and replaced.

If you want to easily diagnose this fault code, then all you have to do is to follow the steps which are mentioned below:

• One of the main reasons for the P0A00 error code is because of the check engine light which has failed.
• Firstly, the mechanic will check the gas cap for the faulty check engine light.
• He will visually inspect the gasp cap for any possible damages or cracks. If there are no damages, he will pull over and retighten the gas cap.
• After making sure that there are no damages in the gas cap, the mechanic will test drive the vehicle and see if the check engine light still appears.
• Another reason, as to why this error code appears is because of the broken or damaged wires.
• Carefully inspect the wiring harness for any possible damages, corrosions or defects which is near the intake manifold bracket.
• Replace the damaged or defective wires quickly.
• As a very rare case, the mechanic will carefully check for any faults in the powertrain control module and replace them if they are found to be damaged.
• After carrying out this diagnosis, the mechanic will reset the vehicle for any error codes and test drive the vehicle again to see if the error code still appears and the check engine light turns on.
• This will help the mechanic to know if the error was fixed and also, it will help him to locate the area as to where the error occurred.
