Error Code P0AF0: What It Means & What To Do?

<<See All OBD Codes

The trouble code P0AF0 can be explained as Drive Motor Inverter Temperature Sensor “A” Circuit High. If the ECM would detect a variation in the voltage coming from the drive motor "A" temperature sensor circuit that is outside the parameters set by the automobile manufacturer, then it would store the P0AF0 error code. This would also give rise to the illumination of the check engine light

We believe that an investment in knowledge pays the best interest. So why not learn more about the P0AF0 error code? This diagnostic fault code is a generic powertrain code, which means that it would apply to the OBD-II equipped vehicles. The specific repair steps can vary as it depends upon the vehicle make and model.

What causes this problem with the Drive Motor Inverter Temperature Sensor "A" Circuit High?

• Drive motor A temperature sensor circuit faulty
• Drive motor A temperature sensor harness is open or small
• Poor electrical wiring and connector issue to the sensor circuit
• ECU faulty that might need repairs

1. 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.
2. Diesel Exhaust Fluid Pump - The diesel exhaust fluid pump needs to work properly if the transmission system has to perform. If it is not functioning, the transmission may slip and cause harsh shifts too. Thus, replace faulty pump now and buy a new one from us!
3. 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).
4. 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.
5. Diagnostic Tools - It is always advisable to use the correct tools and equipment while resolving any OBD code issue as even small mistakes can lead to wrong diagnosis. Thus, always take help from a professional who has the knowledge and experience to such tools in an efficient manner. Buy new quality diagnostic tools from us today!
6. Generator Assembly - When it comes to your automobile, the generator assembly is a pivotal piece of machinery. The generator assembly would make sure to recycle the power of the car battery which is being used while driving the car.
7. HVAC Blower Motor Control Module - One of the most common symptoms of defective HVAC Blower Motor Control Module is a blower motor which might be stuck on just one setting. This auto part is responsible for controlling the speed of the blower motor fan.
8. Motor Assembly - Strange noises would start coming from your car due to faulty motor assembly. Don’t waste time and get them replaced or else P0AF0 code can turn up.

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 P0AF0 here:

Common Symptoms

• Malfunction Indicator Light ON
• Engine misfires
• Engine no starting
• Lean engine condition
• Affected drivability 

Here are some ways with the help of which you will be able to correct the OBD Code P0AF0.

Make sure to mend the faulty engine control module

• Repair or replace the drive motor A temperature sensor
• Resolve sensor circuit faults in relation to poor connectors and wiring and connector issues
• Repair ECU and PCM faults as required
• Check and correct intake manifold and oxygen sensor problems

To do all this, you will need a few high-quality auto parts such as Exhaust systems, DPF, Converter Assembly, HV Control ECU, PCM, Inverter with Converter Assembly and so on. From where will you get them? From your local store? Well, why go there when you can order quality parts with us while sitting in the comfort of your home. So, just browse through our website and order your needed parts today.

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

• A careful inspection of the vehicle is carried out by the mechanic with the help of a scanner.
• After this inspection, he will recover every stored code in the vehicle as well as freeze frame data by inserting a scanner to the diagnostic port of the vehicle.
• He will store this information as it may help him with further diagnosis.
• After the codes are recovered, the vehicle is reset, test- driven to check for the occurrence of the error code.
• He will clearly know that an erratic condition has prevailed if the code does not return quickly.
• But if the code returns instantly, he will then start inspecting the transmission fluid for any leaks.
• In some cases, the transmission fluid can be dirty or it can be contaminated.
• The area of leak will be found and fixed. The dirty or contaminated fluid should be replaced with clear fluid.
• Sometimes the fluid may be not be filled at the correct level, which the mechanic will find during diagnosis. Sometimes, the solenoid itself can be defective which has to be checked for any damages.
• After this, the technician will visually inspect every wires, connectors, harness and fuses for any possible damages or defective and repairs them as needed.
• You must always know that once the error code is repaired, it is always the best idea to test drive and check the vehicle if the error code appears again which can help the technician to know the area of fault and as to how the error code occurred in the vehicle.
• This can easily help the mechanic to fix the error code.

Common Mistakes When Diagnosing the P0AF0 Code

The most common mistake while diagnosing this code is missing out on diagnosing steps which further leads to the expensive and unnecessary replacements. It is always recommended to seek help of experienced diagnostician to avoid any mistakes.
