DTC P0833: Clutch Released Switch Circuit: Testing

  1. Turn the ignition on. With the DRBIII(R), 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 from Open to Closed? If yes, go to next step. If no, go to step  3 .
    2. WARNING: When the engine is operating, DO NOT stand in a direct line with the fan. DO NOT put your hands near the pulleys, belts or fan. DO NOT wear loose clothing.
  2. Conditions that set DTC are not present at this time. The following list may help in identifying the intermittent condition:
    • With the engine running at normal operating temperature, monitor the DRBIII(R) parameters related to the DTC while wiggling the wiring harness. Look for parameter values to change and/or a DTC to set.
    • Review the DRBIII(R) Freeze Frame information to identify under what conditions the DTC set.
    • Refer to any Technical Service Bulletin (TSB) that may apply.
    • Visually inspect the related wiring harness. Look for any chafed, pierced, pinched, or partially broken wires.
    • Visually inspect the related wiring harness connectors. Look for broken, bent, pushed out, or corroded terminals.

      Were any of the above conditions present? If yes, repair as necessary. If no, test is complete.

  3. Turn the ignition off. Disconnect the CPP switch harness connector. Connect a jumper wire between the ground circuit and the clutch upstop switch signal circuit in the CPP switch harness connector. Turn the ignition on. With the DRBIII(R), monitor the Clutch Upstop Switch status. Did the Clutch Upstop Switch status change from Open to Closed? If yes, replace the CPP switch. If no, go to next step.
  4. Turn the ignition off. Disconnect the CPP switch harness connector. Disconnect the PCM harness connectors. Measure the resistance between ground and the clutch upstop signal circuit in the CPP switch harness connector. Is the resistance less than 100 ohms? If yes, repair the clutch upstop circuit for a short to ground. If no, go to next step.
  5. Measure the resistance of the clutch upstop signal circuit between the CPP switch harness connector and the PCM harness connector. Is the resistance less than 5.0 ohms? If yes, go to next step. If no, repair the clutch upstop signal circuit for an open.
  6. Turn the ignition off. Reconnect the PCM harness connectors. Using a 12-volt test light connected to 12.0 volts, probe the ground circuit in the CPP switch harness connector. Does the test light illuminate brightly? If yes, go to next step. If no, repair the ground circuit for an open.
  7. There are no possible causes remaining, replace PCM.
