P2C4C
Clutch Actuator Position Sensor Circuit Low
What it means
P2C4C means Clutch Actuator Position Sensor Circuit Low.
Where it lives
For P2C4C, the circuit described runs through the sensor. The description of P2C4C reports a fault at the sensor.
Check these first
- A short to ground on the clutch actuator position sensor signal
- A clutch actuator position sensor that lost internal resistance
- Fluid contamination at the clutch actuator sensor connector
- A pinched sensor harness near the clutch
What to do next
- Read clutch actuator position on a scan tool
- Disconnect the sensor and see if the low reading clears
- Test the sensor signal wire for a short to ground
- Inspect the sensor harness for pinches
- Replace the clutch actuator position sensor if the circuit tests good
- Clear the code and retest
