Checking components and wiring

Check the clutch pedal sensor and engine control module (ECM) connectors. Check for contact resistance and oxidation.

Check the signal cable between engine control module (ECM) terminal #B15 (#B25) and clutch pedal sensor terminal #2 (component side). Check for an open-circuit. Check for a short-circuit to supply voltage.

Check the signal ground cable between engine control module (ECM) terminal #B4 (#B14) and clutch pedal sensor terminal #4 (wiring side). Check for an open-circuit.

HINT: With the ignition on, the power supply to the clutch pedal sensor must be approximately 5 V (measured with the clutch pedal sensor disconnected), measured between terminals #2 and #4 (wiring side).
