P0A30 - OBD Trouble Code

<<See All OBD Codes

The trouble code P0A30 can be described as Drive Motor “B” Temperature Sensor Circuit Issue. This code is a generic trouble code, meaning it applies to all vehicles equipped with the OBD-II system, especially those made from 1996 up to present. It’s also more common among Audi, Citroen, Chevrolet, Ford, Hyundai, Nissan, Peugeot, and Volkswagen vehicles. Specifications on the definition, troubleshooting, and repairs, of course, vary from one make and model, powertrain configuration type, to another. One thing which you must keep in mind that its symptoms as well as causes would surely vary as it depends upon a number of things.

Don’t worry if P0A30 error code is triggering again and again. We offer wide range of auto parts at affordable prices to our dear customers. The drive motor temperature sensor is being monitored by the engine control module. This trouble code would be set by the ECM when the motor temperature sensor would not be as per the specifications set by the manufacturer. The engine control module, powertrain control module or the transmission control module monitors this circuit depending upon the particular automobile.

What causes this problem with the Drive Motor "B" Temperature Sensor Circuit?

• Fault in the motor temperature sensor
• Motor temperature sensor harness might be opened or sometimes shorted
• Motor temperature sensor circuit having damaged electrical connection
• Powertrain Control Module faulty

1. Powertrain Control Module - Do you remember when was the last time you got your car Powertrain Control Module checked up? A dirty Powertrain Control Module can cause a lot of issues like displaying P0A30 code.
2. Engine Control Module - Everything is fine with Engine Control Module and still P0A30 code triggering? Then you must get your Engine Control Module checked.
3. Electronic Control Unit - Check for faulty ECU and replace if required. Buy new ECU components now and replace the faulty one immediately.
4. Diagnostic Tools - Use professional OBD scan tools to diagnose an OBD code error problem. Buy quality diagnostic tools from us now!

Our main motive is to achieve customer satisfaction and that’s why we will help you to diagnose P0A30 code by mentioning some major symptoms below:

Common Symptoms

• Check Engine Light Illumination
• Engine stalling and not starting

If you wish to correct this fault code, then you have to follow certain steps. Correcting a problem needs your careful attention. Here are some ways with the help of which you will be able to correct the OBD Code P0A30:

• Fix the defective motor temperature sensor
• Make sure to repair the faulty motor assembly
• Restore the flawed motor temperature sensor harness
• The malfunctioning auto transmission shift solenoid should be repaired or replaced as per the need
• Carefully adjust the faults in the motor temperature sensor circuit
• It is necessary to perform proper service of the unsound powertrain control module

There is no need to be anxious as Parts Avatar – Car Parts Online is here to help you out! We have high grade Engine Control Module, PCM, Hybrid Motor Temperature Sensor, Temperature Sensor, Electronic Control Unit, Motor and a lot more for our precious customers.

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

• The mechanic or the technician will use a diagnostic scanner or code reader like DVOM to visually scan for the error codes in the vehicle.
• After performing a careful inspection, every of the stored codes and freeze frame data are retrieved as it can help down the way for further diagnosis process.
• Most often he has to inspect the solenoid itself to see if they are faulty or damaged. Additional error codes that are stored in the vehicle are also addressed.
• The mechanic performs a continuity test between the PCM and solenoid to check the resistance.
• If the solenoid or the control modules are not faulty, he will then retune the code and test drive the vehicle.
• Inspect for faults in the motor temperature sensor and the circuit issue and repair or replace the parts as required.
• On test driving, if the P0A30 code does not return soon, he will know that an erratic condition exits.
• If everything seems to function properly, check for problems with the PCM as sometimes the PCM can read the information wrongly and depict wrong OBD error codes.

Common Mistakes When Diagnosing The P0A30 Code

• Non-performance of the hybrid transaxle assembly
• Failure in the powertrain control module
• Problematic motor temperature sensor circuit
• Faulty wiring and connectors in relation to the sensor and circuits
• There can be some faults in the wiring
