[SOLVED] P1Af6 Code: Low Voltage In Hybrid Battery Isolation Sensor – Fix Now!

The P1AF6 automobile fault code is a common issue that triggers the Engine Light ON or Service Engine Soon Warning Light. The cause of this fault code could be due to a faulty Power Inverter Control Module (PIM), an open or shorted PIM harness, or a poor electrical connection in the PIM circuit. The importance of repairing this issue lies in the fact that it affects the performance of the vehicle.

The difficulty level of repairing this issue is moderate, and it takes approximately 1.0 hour to fix. To interpret the fault code, one needs to check the possible causes listed above and visually inspect the related wiring harness and connectors.

If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p1af6 fault code.

Here are the symptoms to look out for:

  • The P1AF6 fault code in an automobile can cause several symptoms, including the engine light turning on or the service engine soon warning light appearing.
  • Other symptoms may include reduced engine power, decreased fuel efficiency, and difficulty starting the engine.
  • Additionally, the vehicle may experience rough idling or stalling, and there may be a noticeable decrease in acceleration.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle and ensure safe driving conditions.

The P1AF6 automobile fault code can be caused by various factors, including a faulty PIM or poor electrical connection.

  • The automobile fault code P1AF6 can be caused by a faulty Power Inverter Control Module (PIM), an open or shorted PIM harness, poor electrical connection in the PIM circuit, or the need to reprogram the PIM.

To fix the p1af6 fault code, check the possible causes and inspect the wiring harness and connectors for any damage or corrosion.

  • To fix the automobile fault code p1af6, first, check the possible causes listed above.
  • Then, visually inspect the related wiring harness and connectors.
  • Look for any 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 P1AF6 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 the P1AF6 fault code will depend on the hourly rate charged by the repair shop and the time taken to complete the repair.

The P1AF6 code is related to the Drive Motor 2 Control Module.

It indicates a problem with the Hybrid Battery Voltage Isolation Sensor Circuit. The Motor Control Modules (MCMs) test for Loss of Isolation (LOI) between the HV circuits and vehicle chassis. The MCM measures the voltage drop across one of the resistors to detect LOI.

Without a loss of isolation, the MCM should measure about half of the high voltage potential. The Mid-pack voltage value is then doubled by the software and displayed on a scan tool as Motor 1 Isolation Voltage or Motor 2 Isolation Voltage. When a loss of isolation is present, the motor isolation voltage display will indicate voltage that is more or less than actual hybrid battery high voltage.

What are the possible causes of the P1AF6 fault code in an automobile?

If you see the engine light on or service engine soon warning light in your automobile, it could be due to the P1AF6 fault code. This code can be caused by a faulty power inverter control module (PIM), an open or shorted PIM harness, or a poor electrical connection in the PIM circuit. To fix this issue, you should reprogram the PIM and visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins.
