The P1F3C automobile fault code indicates a problem with the Voltage Control Unit (VCU) in your vehicle.

This can cause the engine light to turn on, indicating a potential issue with the car’s performance.

The most common causes of this fault code are a water pipe leak, a faulty radiator fan, or a poor electrical connection in the VCU circuit. It is important to address this issue promptly to avoid further damage to your vehicle. The repair process involves visually inspecting the wiring harness and connectors, checking for damaged components, and looking for broken or corroded connector pins.

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

The automobile fault code P1F3C 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 P1F3C will be between $75 and $150, depending on the repair time required.

The P1F3C fault code indicates that there is a problem with the Voltage Control Unit (VCU) in the automobile. The VCU controls the voltage and electric power between the battery module and the motor power inverter (MPI) module.

The VCU measures the temperature of the IGBT chip within the VCU to detect overheating and sends this information to the motor control module (generator).

If the motor control module (generator) receives continuous overheating information for the prescribed time or more, it will detect a malfunction and store a DTC, resulting in the P1F3C fault code.

What are the possible causes of the P1F3C automobile fault code?

If you’re experiencing the P1F3C fault code, your engine light may be on. This could be due to a water pipe leak, faulty voltage control unit (VCU), or a poor electrical connection in the VCU circuit. To fix the issue, visually inspect the wiring harness and connectors for any damage or corrosion. Check for broken or bent pins and damaged components.

How can I visually inspect the related wiring harness and connectors to fix the P1F3C fault code?

To fix the P1F3C fault code, start by checking the possible causes such as a water pipe leak, faulty radiator fan, or a faulty Voltage Control Unit (VCU). Then, visually inspect the related wiring harness and connectors for any damaged components. Look for broken, bent, pushed out, or corroded connector’s pins to ensure there is no open or shorted circuit or poor electrical connection.

What are the steps to take if I find damaged components or broken, bent, pushed out, or corroded connector’s pins while fixing the P1F3C fault code?
