Code P1C20 Subaru Description
The P1C20 diagnostic trouble code (DTC) for Subaru vehicles indicates that the drive motor 'A' inverter voltage is too low. This code typically points to an issue with the inverter system that controls the electric motor in hybrid or electric vehicles. The inverter is responsible for converting the direct current (DC) power from the battery into alternating current (AC) power to drive the electric motor. When the voltage from the inverter is too low, it can result in reduced performance and efficiency of the electric motor, affecting the overall drivability of the vehicle.
Common Causes of P1C20 Subaru
- Faulty inverter system components
- Wiring or connection issues
- Battery issues
- Software glitches or calibration errors
- Environmental factors such as extreme temperatures
Symptoms of P1C20 Subaru
- Reduced power output
- Poor acceleration
- Decreased fuel efficiency
- Loss of propulsion
- Illumination of the check engine light
How to Fix P1C20 Subaru
- Diagnose the specific cause of the low inverter voltage using a scan tool to read and interpret the DTC.
- Inspect the inverter system components, wiring, and connections for any visible damage or corrosion.
- Test the battery voltage and charging system to ensure they are functioning properly.
- Update or reprogram the inverter system software to address any calibration errors.
- Replace faulty inverter components such as the inverter control module or inverter assembly if necessary.
Cost to Fix P1C20 Subaru
