Clutch Pedal Position Sensor Circuit High Input
The clutch pedal position sensor is sending a high voltage signal to the computer.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
The clutch pedal position sensor detects how far down the clutch pedal is pressed and sends this info to the engine control module (ECM). If the sensor sends a signal that is too high, the ECM thinks the pedal is pressed more than it actually is, which can cause shifting issues or affect engine performance.
What the computer is actually seeing
The computer sees a voltage from the clutch pedal position sensor that is above the expected range, typically greater than 4.5 volts when it should be around 0.5 to 2.5 volts with the pedal in its normal position.
What a healthy reading looks like
Normal voltage from the sensor should be between 0.5V to 4.5V depending on pedal position. Above 4.5V indicates a problem.
Guided diagnostic — the DiagCoach way
Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.
- 1Check the condition of the connector and wiring to the clutch pedal position sensor. Look for corrosion, damaged wires, or loose connections.
- 2Using a multimeter, check the voltage at the sensor connector with the pedal released. Voltage should be between 0.5V and 1.5V. If it's high (above 4.5V), continue to the next step.
- 3Inspect the sensor itself for physical damage or misalignment. If no visible issues, proceed to check for shorts in the wiring harness. Disconnect the sensor and check for continuity to ground and power supply.
- 4If wiring checks out, replace the clutch pedal position sensor as it is likely faulty. After replacing, clear the code and test drive.
Common causes
- Faulty clutch pedal position sensor
- Shorted wiring or connectors
- Corrosion on the sensor connection
- Improper installation of the sensor
- Issues in the ECM itself
