The P1AF0 automobile fault code indicates a problem with the Drive Motor 1 Control Module HybridEV Battery. The most common symptom is the Engine Light ON or Service Engine Soon Warning Light.

The cause of this issue could be a faulty control module, an open or shorted harness, or a poor electrical connection. The importance of repairing this issue lies in the fact that it affects the performance of the hybrid or electric vehicle. The repair difficulty is moderate, and the fix involves visually inspecting the wiring harness and connectors, checking for damaged components, and looking for broken, bent, pushed out, or corroded connector’s pins.

The repair time is estimated to be around 1.0 hour. To interpret the fault code, one needs to check the possible causes listed above.

If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p1af0 fault code. Here are the symptoms to look out for:

  • The P1AF0 fault code in an automobile can cause the following symptoms: Engine Light ON, Service Engine Soon Warning Light ON.

The P1AF0 fault code can be caused by issues with the drive motor control module, hybridEV battery, or their electrical connections.

  • The automobile fault code P1AF0 can be caused by a faulty Drive Motor 1 Control Module Hybrid/EV Battery.
  • It can also be caused by an open or shorted Drive Motor 1 Control Module Hybrid/EV Battery harness.
  • Additionally, a poor electrical connection in the Drive Motor 1 Control Module Hybrid/EV Battery circuit can also trigger this fault code.

To fix the p1af0 automobile fault code, check the possible causes and inspect related components for damage or corrosion.

  • To fix the automobile fault code p1af0, 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 P1AF0 indicates a problem with the hybrid battery system. The estimated repair time for this fault code is 1.0 hour. The cost of fixing this issue can vary depending on the auto repair shop, but it is common for them to charge between $75 and $150 per hour.

Other factors that may influence the cost include the severity of the problem, the type of vehicle, and the availability of replacement parts.

It is important to address this issue promptly to avoid further damage to the vehicle and ensure its safe operation.

The P1AF0 fault code relates to the Drive Motor 1 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 either 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. 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 P1AF0 fault code?

If you see the engine light on or service engine soon warning light, it could be due to the P1AF0 fault code. This code is caused by a faulty drive motor control module in the hybrid/EV battery, an open or shorted harness, or poor electrical connection. To fix this issue, inspect the wiring harness and connectors for any damage or corrosion. Check for broken, bent, pushed out, or corroded connector pins.

How can I visually inspect the wiring harness and connectors related to the P1AF0 fault code?

If you’re experiencing the P1AF0 fault code, indicated by the Engine Light ON or Service Engine Soon Warning Light, you may need to visually inspect the wiring harness and connectors related to the Drive Motor 1 Control Module Hybrid/EV Battery. This fault code can be caused by a faulty module or poor electrical connection due to an open or shorted harness. To fix this issue, check for damaged components and inspect the connectors for broken, bent, pushed out, or corroded pins.

What should I do if I find damaged components or broken, bent, pushed out, or corroded connector’s pins while inspecting the P1AF0 fault code?

If you find damaged components or broken, bent, pushed out, or corroded connector’s pins while inspecting the P1AF0 fault code, you should visually inspect the related wiring harness and connectors. Check for any damaged components and look for any broken, bent, pushed out, or corroded connector’s pins. This will help you identify the cause of the fault and allow you to fix it accordingly. Remember to check the “Possible Causes” listed above and ensure that the Drive Motor 1 Control Module Hybrid/EV Battery harness is not open or shorted and that the circuit has a good electrical connection.
