Error Code P0A39: What It Means & What To Do?

<<See All OBD Codes

The trouble code P0A39 can be explicated as Generator Temperature Sensor Circuit High. The generator temperature sensor is being monitored by the engine control module. This trouble code would be set by the ECM when the generator temperature sensor would not be as per the specifications set by the manufacturer.

 

OBD-II Code P0A39 is defined as a Generator Temperature Sensor Circuit High. When an error is detected in the Hybrid Motor Temperature Sensor circuit, the powertrain control module (PCM) will set code P0A39.

Do you want to gain some more knowledge about the P0A39 trouble code? The engine control module, powertrain control module or the transmission control module monitors this circuit depending upon the particular automobile.

 

The resistance of the thermistor in the motor temperature sensor changes with the change in the fluid temperature. Based on the signal from the motor temperature sensor, the ECU will limit the load to prevent the hybrid motor from overheating and checks the motor temperature sensor for a wiring malfunction and the sensor for malfunction.

 

What causes this problem with the Generator Temperature Sensor Circuit High?

 

• Malfunctioning generator temperature sensor
• Generator temperature sensor harness open/short
• Generator temperature sensor circuit wiring and connector issue

Common Symptoms

 

• Check engine light can start flashing up
• High voltage system not functioning properly
• Problems in handling the vehicle

The repairs which you will have to do to correct this fault code are simply straightforward; you can surely pinpoint the necessary repairs on the basis of your diagnosis. Have a look at some common fixes:

 

• You must fix the defective automatic transmission module
• Make sure to mend the faulty generator assembly
• The malfunctioning generator temperature sensor harness should be repaired or replaced as per the need
• Carefully adjust the faults in the generator temperature sensor circuit
• It is necessary to perform proper service of the unsound engine control module
• Adjust the flawed generator temperature sensor

There is no need to get strained if your OBD Code is still flashing up as we are here at your service. Have a look at our superior variety of ECM, Generator Temperature Sensor and many more. Now all your problems would vanish within no time.

Here are some steps which you should follow in order to diagnose this fault code:

 

• This is a general type of error code which is diagnosed with the help of a scanner.
• The mechanic will insert a scanner to diagnostic port of the vehicle and recover the codes and freeze frame data.
• If he happens to find any additional error codes, he has to address them as well.
• Once it is done, he has to reset the vehicle, and then test drive to see if the error code appears.
• If the error code does not return, then there can be an erratic condition.
• But, if the error code returns, then the mechanic has to check the transmission fluid.
• If the transmission fluid is dirty or if it is below the expected level, it has to be refilled or the dirty fluid has to be replaced.
• Also, the mechanic can check for any sign of leaks, and quickly fix the issue.
• Then the mechanic has to check the wires, connectors and other electrical components and quickly replace them if he finds them to be damaged or defective.
• If the issues are not yet sorted out, then the mechanic will use a digital voltmeter/ ohmmeter and connect it to the vehicle.
• Once the circuit is inspected, he will thoroughly check all the harness and repair them accordingly.
• In most cases, this error code can arise mostly because of any shorted wires or dirty or contaminated transmission fluid.
• Whenever the mechanic or a trained professional, repairs any of the component like wires or connectors, he will reset the code and test drive the vehicle again to see if the error code appears again.
• This can actually help the mechanic to know if the problem is fixed.

Common Mistakes When Diagnosing the P0A39 Code

 

• Some issues related to the wiring
• Failure in the hybrid transaxle assembly
• Faults in the powertrain control module
