P0AF1 OBD Error Code: Problem & Solutions

<<See All OBD Codes

OBD code P0AF1 means Drive Motor Inverter Temperature Sensor “A” Circuit Intermittent condition. If this code is stored then the first indication will be the illumination of the Check Engine Light on the dashboard. Along will that you might notice engine lean condition and reduced performance.

OBD-II Code High voltage system may not operate is defined as a Drive Motor "A" Temperature Sensor Circuit Intermittent. The Hybrid Motor Temperature Sensor is built into the Hybrid Motor Assembly. When a failure is detected in the Hybrid Motor Temperature Sensor circuit, the engine control module (PCM) will set code P0AF1.

The Engine Control Module (ECM) monitors the Drive Motor 'A' Temperature Sensor. The ECM sets the OBDII code when the Drive Motor 'A' Temperature Sensor is not to factory specifications.

What causes this problem with the Drive Motor Inverter Temperature Sensor 'A' Circuit Intermittent/Erratic?

• Drive Motor “A” Temperature Sensor damage
• Wiring and connectors in relation to the sensor and circuit fault
• Drive Motor Harness faulty
• Powertrain Control Module failure
• Electronic Control Module Failure

1. Engine Control Module - If there is any corrosion or breaks in the internal wiring of the harness, then it can cause a short in the ECM or can also cause corrosion in the ECM through the wiring harness. You can always rely on us as we have the best auto parts for our customers.
2. Powertrain Control Module - The onboard computer, or powertrain control module is the brain of the engine control system. Now if the brain is not working properly, then neither is the car engine. Get it replaced before the situation gets worse.
3. Electronic Control Unit - Is your car jump starting on reverse polarity? Or are you facing some intermittent starting issues? If yes, then it indicates that your electronic control unit is bad. So, it is very important to replace the defective electronic control unit with us at equitable prices.
4. Diagnostic Tools - Buy quality diagnostic tools to check and diagnose OBD code P0AF1 error with the help of experienced mechanic. Visit us today!
5. Generator Assembly - If there are some faults in your car generator assembly, then it would lead to illumination of the service engine light, dim lights as well as some odd noises might start coming. Buy top notch car generator assembly from us at economical prices.
6. HVAC Blower Motor Control Module - It is an electrical component, which is a part of the automobile's heating and air conditioning system. It makes sure to control the blower motor fan speed. If there are some defects in it, then it would be nice if you get it replaced on time.
7. Motor Assembly - The motor assembly is a very important component of your vehicle. When it stops working, so does your car. Get it checked and replace if needed.

It is vital 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 P0AF1 here:

Common Symptoms

• Check Engine Light Illumination
• Engine not starting
• Affected performance

Want to correct the Trouble Code P0AF1? Read these points mentioned below:

• Restore the flawed powertrain control module
• Repair or replace the quirky motor temperature sensor harness
• Carefully adjust the faults in the motor assembly
• Adjust the flawed motor temperature sensor circuit
• Rehabilitate the defaults in the motor torque sensor
• Repair or replace defective auto transmission shift solenoid

Apart from this, you might need to replace other damaged parts too Inverter/Converter Assembly, HV Control ECU and more. You can easily find all these parts with us. Not only that you can get these parts shipped to your door free, if your cart value happens to exceed $99.

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

• As an initial step the mechanic will carefully inspect the vehicle with the help of a scanner.
• After this, the technician will connect a scanner to the diagnostic code so that he can recover all the codes and freeze frame data.
• Note down this information as it can clearly help for further diagnosis.
• After careful inspection, he will reset the code and test drive your vehicle to check for reappearance of the codes.
• He will know that an intermittent condition persists, if the code does not return instantly.
• But if the error code returns quickly, the vehicle is test driven, and then he has to inspect the transmission fluid.
• The transmission fluid can be dirty or there can be any blocks in the transmission filter which can be replaced instantly.
• At times, the fluid level will be insufficient which has to be fixed immediately. If he comes across any leaky areas, he will fix them too.
• Once the fluid is checked for appropriate level, then every other component like wires and connectors have to be checked for possible damages.
• If any of the component is damaged, the mechanic will replace them quickly.
• Most often, whenever the mechanic carries out any repair work, he will reset the code and test drive your car, to check if the codes return immediately. This can preferably help the mechanic to know what caused this error code in the vehicle.

Common Mistakes When Diagnosing The P0AF1 Code

• Powertrain control module might start failing
• Some issues related to the wiring
• Faults in the hybrid motor assembly
