Clutch Position Sensor Circuit High Input

This code indicates too high a voltage in the clutch position sensor circuit.

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 position sensor is giving a reading that's higher than expected, which suggests there may be an issue with the sensor itself or its wiring.

What the computer is actually seeing

The Engine Control Module (ECM) is looking for a voltage signal from the clutch position sensor typically between 0.5V to 4.5V, and it sees a voltage that is above 4.5V.

What a healthy reading looks like

Clutch position sensors should typically output between 0.5V and 4.5V when the clutch is engaged and disengaged, respectively.

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.

  1. 11. Check the wiring and connectors for damage or corrosion on the clutch position sensor. If damaged, repair or replace them. Decision Point: Were any issues found? YES: Repair the wiring and retest. NO: Go to step 2.
  2. 22. Use a multimeter to measure the voltage at the clutch position sensor connector. Expected range: 0.5V to 4.5V. Decision Point: Is the voltage within range? YES: Continue to step 3. NO: Replace the clutch position sensor.

Common causes

  • Faulty clutch position sensor
  • Wiring issues (shorts or opens)
  • Connector problems (corrosion or looseness)
  • Faulty ECM
