The P1A4F fault code in automobiles indicates a problem with the Power Inverter 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.

It is important to address this issue promptly as it can lead to reduced fuel efficiency and even damage to the engine. The repair process involves visually inspecting the wiring harness and connectors, checking for damaged components, and looking for broken, bent, pushed out, or corroded connector pins.

The repair time for this issue is estimated to be around 1.0 hour.

The automobile fault code P1A4F has an estimated repair time of 1.0 hour. The cost of fixing this fault code is influenced by the repair time. Most auto repair shops charge between $75 and $150 per hour for their services.

Therefore, the fixing cost of P1A4F will be between $75 and $150, depending on the repair time required.

The P1A4F fault code is related to the drive motor control modules in the Power Inverter Module.

These modules are not serviced separately and any internal malfunction will trigger the Diagnostic Trouble Code. The code will also set if a service module has been installed but not yet programmed. In particular, the P1A4F code indicates that Drive Motor 1 Control Module is not programmed.

What are the possible causes of the P1A4F fault code in an automobile?

If you see the engine light on or the service engine soon warning light, it could be due to the P1A4F fault code. This code is usually caused by a faulty Power Inverter Module (PIM), an open or shorted PIM harness, or a poor electrical connection in the PIM circuit. 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 one visually inspect the wiring harness and connectors related to the Power Inverter Module (PIM)?

If the engine light is on due to a faulty Power Inverter Module (PIM), it is important to visually inspect the related wiring harness and connectors. This can be done by checking for damaged components and looking for broken, bent, pushed out, or corroded connector’s pins.
