- 2Check the connections at the clutch pedal sensor for oxidation and loose contacts
- 3Use a multimeter to see whether the signal wire from the sensor has voltage with the ignition off
- 4Look for chafed wires and damaged insulation on the wire to the sensor
- 5If the wire is intact, have a workshop with diagnostic equipment check the sensor and the control module
