The P1AF4 fault code in automobiles refers to a problem with the Power Inverter Control Module (PIM). The most common symptom is the illumination of the Engine Light or Service Engine Soon Warning Light.

The cause of this fault code could be a faulty 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 can affect the performance of the 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.

It is essential to interpret the fault code correctly to identify the root cause of the problem and fix it accordingly.

If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p1af4 fault code.

Here are the symptoms to look out for:

  • The P1AF4 fault code in automobiles 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 P1AF4 automobile fault code can be caused by a faulty PIM, open harness, poor electrical connection, or the need for a reprogram.

  • The automobile fault code P1AF4 can be caused by several factors.
  • These include a need to reprogram the Power Inverter Control Module (PIM), a faulty PIM, an open or shorted PIM harness, and poor electrical connection in the PIM circuit.
  • It is important to address all of these potential causes in order to effectively resolve the P1AF4 fault code.

Below are the possible fixes for the automobile fault code p1af4, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code p1af4, 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 fault code P1AF4 is a common issue in automobiles.

The estimated repair time for this fault code is 1.0 hour. The cost of fixing this fault code varies between $75 and $150 per hour, depending on the auto repair shop. The cost may also vary based on the severity of the issue and the type of vehicle.

It is important to get this fault code fixed as soon as possible to avoid any further damage to the vehicle.

The P1AF4 code is related to the drive motor generator Power Inverter Control Module (PIM).

It indicates a problem with the Hybrid Battery Voltage Isolation Sensor Circuit. The Motor Control Modules (MCMs) measure the hybrid battery High Voltage (HV) with internal sensors. The MCMs test for Loss Ff Isolation (LOI) between the HV positive or negative circuit and vehicle chassis.

The MCMs measure the voltage drop across two resistors to detect LOI. The mid-pack voltage value is doubled by the software and displayed on a scan tool as Motor 1 Isolation Voltage or Motor 2 Isolation Voltage. The MCM monitors the LOI voltage measuring circuitry for correct operation.

What are the possible causes of the P1AF4 automobile fault code?

If you see the engine light on or service engine soon warning light, it could be due to the P1AF4 fault code. The possible causes of this fault code include a faulty power inverter control module (PIM), an open or shorted PIM harness, a poor electrical connection in the PIM circuit, or the need to reprogram the PIM. To fix this issue, you should visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.

How can I fix the P1AF4 automobile fault code?

If you’re experiencing the P1AF4 fault code, which is indicated by the engine light or service engine soon warning light turning on, there are a few possible causes. These include a faulty power inverter control module (PIM), an open or shorted PIM harness, or poor electrical connection in the PIM circuit. To fix the issue, you should visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector pins.
