DTC P0833: Clutch Released Switch Circuit: Testing
- With the DRBIII® scan tool, monitor the clutch upstop switch. Depress the clutch pedal completely to the floor and release all the way up several times. Did the clutch upstop switch state change open to closed? If yes, see INTERMITTENT CONDITION under SELF-DIAGNOSTIC SYSTEM. If no, go to next step.
- Disconnect the clutch pedal position switch harness connector. Connect a jumper wire between the ground circuit and the clutch upstop switch signal circuit in the clutch pedal position switch harness connector. With the DRBIII® scan tool, monitor the clutch upstop switch status. Did the clutch upstop switch status change from OPEN to CLOSED? If yes, replace the clutch pedal position switch. If no, go to next step.
- Turn the ignition off. Disconnect the clutch pedal position switch harness connector. Disconnect the PCM harness connectors. Measure the resistance of the clutch upstop signal circuit in the clutch pedal position switch harness connector to ground. Is the resistance below 100 ohms? If yes, repair the clutch upstop circuit for a short to ground. If no, go to next step.
- Turn the ignition off. Disconnect the clutch pedal position switch harness connector. Disconnect the PCM harness connectors. Measure the resistance of the clutch upstop signal circuit between the clutch pedal position switch harness connector and the appropriate terminal of Miller Special Tool (8815). Is the resistance below 5.0 ohms? If yes, go to next step. If no, repair the clutch upstop signal circuit for an open.
- Turn the ignition off. Disconnect clutch pedal position switch harness connector. Using a 12-volt test light connected to 12-volts, probe the (Z12) ground circuit in the clutch pedal position switch harness connector. Does the test light illuminate brightly? If yes, go to next step. If no, repair the (Z12) ground circuit for an open.
- Before continuing, check the PCM harness connector terminals for corrosion, damage, or terminal push out. Repair as necessary. If there are no possible causes remaining, replace and program the PCM. See PROGRAMMING .
CAUTION:
Do not probe the PCM harness connectors. Probing the PCM harness connectors will damage the PCM terminals resulting in poor terminal to pin connection. Install Miller Special Tool (8815) to perform diagnosis.
