If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p1af2 fault code.

Here are the symptoms to look out for:

  • The P1AF2 fault code in an automobile can cause several symptoms.
  • The most common symptom is the illumination of the engine light or service engine soon warning light.
  • Other symptoms include reduced engine power, decreased fuel efficiency, and difficulty starting the engine.
  • The vehicle may also experience stalling or hesitation during acceleration.
  • Additionally, the driver may notice a decrease in overall performance and responsiveness of the vehicle.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle.

The P1AF2 fault code can be caused by issues with the Drive Motor 2 Control Module, HybridEV Battery, or their electrical connections.

  • The automobile fault code P1AF2 can be caused by a faulty Drive Motor 2 Control Module Hybrid/EV Battery.
  • It can also be caused by an open or shorted Drive Motor 2 Control Module Hybrid/EV Battery harness.
  • Additionally, a poor electrical connection in the Drive Motor 2 Control Module Hybrid/EV Battery circuit can also trigger this fault code.

To fix the p1af2 automobile fault code, check the possible causes and inspect related components for damage or corrosion.

  • To fix the automobile fault code p1af2, first, check the possible causes listed above.
  • Then, visually inspect the related wiring harness and connectors.
  • Look for damaged components and check for broken, bent, pushed out, or corroded connector’s pins.
  • This fix will take an estimated repair time of 1.0 hour.

The automobile fault code P1AF2 can be diagnosed and fixed within an estimated repair time of 1.0 hour. The cost of repair is influenced by the repair time, which is commonly charged between $75 and $150 per hour by most auto repair shops. Therefore, the total cost of diagnosis and fixing for the P1AF2 fault code will depend on the hourly rate charged by the repair shop and the time taken to complete the repair.

The P1AF2 fault code relates to the Drive Motor 2 Control Module HybridEV Battery Voltage System Isolation L.

The power inverter module contains three motor control modules and the hybrid powertrain control module.

The motor control modules test for loss of isolation between the high-voltage positive circuit or high-voltage negative circuit and vehicle chassis. The motor control module measures hybrid battery high voltage with several internal sensors.

The motor control modules’ loss of isolation is detected through the use of two high-impedance resistors and voltage measuring circuitry. The motor isolation voltage display will indicate voltage that is more or less than actual hybrid battery high voltage when a loss of isolation is present.

What are the possible causes of the P1AF2 fault code?

If you see the engine light on or service engine soon warning light, it could be due to the P1AF2 fault code.
