Guide To P0AF2 OBD Error Code Solutions

<<See All OBD Codes

The trouble code P0AF2 can be described as Drive Motor Inverter Temperature Sensor “B” 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 P0AF2 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 Inverter Temperature Sensor "B" 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. Generator Assembly - Some common symptoms of bad generator assembly are weak or dead car battery, weird smells and the warning light on the dashboard might start illuminating. It would be nice if you get it replaced on time.
2. HVAC Blower Motor Control Module - If there is a failure in the blower motor resistors’ internal components, then it might cause the HVAC blower motor control module to malfunction, or it might not function at all on one or more of the settings. Get it replaced before the situation gets worse.
3. Motor Assembly - One of the most common causes of the failure in the motor assembly can be due to neglecting oil changes. Remember that oil is the lifeblood for engines. You can always rely on us as we have the best auto parts for our customers.
4. Engine Control Module - There can be some engine performance issues due to faulty engine control module. If the ECM fails or has any problems it can lead to performance issues with the vehicle like misfires, hesitation, loss of power, and sometimes even decreased fuel economy.
5. Powertrain Control Module - PCM stands for powertrain control module. It is a car part, a control unit which is utilized on motor vehicles. It is generally a combined control unit, consisting of the engine control unit (ECU) and the transmission control unit (TCU).
6. Electronic Control Unit - If your automobile's check engine light remains on constantly, and never goes off, there's a good chance that your vehicle has a damaged electronic control unit. There are a lot of reasons why a car's check engine light will remain on. The most common reason is a defective ECU.
7. Diagnostic Tools - Take help of a professional mechanic to diagnose OBD code error. Use high grade diagnostic tools to resolve this issue. Buy new tools and equipment form us!

Common Symptoms

• Check Engine Light Illumination
• Engine stalling and not starting

We have listed out some ways which would help you to correct the occurrence of OBD Code P0AF2. They are mentioned here as follows:

• 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 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 Inverter/Converter Assembly, HV Control ECU 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:

• 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 P0AF2 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 P0AF2 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
