DTC P0833: Clutch Released Switch Circuit: Testing

  1. Using scan tool, monitor CLUTCH UPSTOP SWITCH state. Completely depress and release clutch pedal several times. If CLUTCH UPSTOP SWITCH state changes from CLOSED when released to OPEN when fully depressed, go to next step.If CLUTCH UPSTOP SWITCH state does not change from CLOSED when released to OPEN when fully depressed, go to step  3 .
  2. Conditions that set DTC are not present at this time. Perform the following to help identify intermittent condition:
    • With engine running at normal operating temperature, wiggle related wiring harness while monitoring related parameters on scan tool. If voltage changes or DTC sets while wiggling wiring harness, repair connectors or wiring harness where wiggling caused voltage to change or DTC to set.
    • Review freeze frame information on scan tool. Duplicate conditions present when DTC was set.
    • Refer to any Technical Service Bulletins (TSBs) that may apply.
    • Visually inspect related wiring harness. Check for chafed, pierced, pinched or partially broken wires.
    • Visually inspect related wiring harness connectors. Check for broken, bent, pushed out or corroded terminals.

    If a problem is found, repair as necessary. If no problems are found, test is complete.

  3. Disconnect Clutch Pedal Position (CPP) switch harness connector located at top of clutch pedal. Connect a jumper wire between signal circuit (Light Green/Black wire) and ground circuit (Black wire) at CPP switch harness connector. If CLUTCH UPSTOP SWITCH state does not change from OPEN to CLOSED, go to next step. If CLUTCH UPSTOP SWITCH state changes from OPEN to CLOSED, replace CPP switch.
  4. Turn ignition off. Disconnect PCM harness connectors. PCM is located in engine compartment, between air cleaner and radiator. Measure resistance between ground and signal circuit (Light Green/Black wire) at CPP switch harness connector. If resistance is 100 ohms or more, go to next step. If resistance is less than 100 ohms, repair short to ground in signal circuit.
  5. Measure resistance of signal circuit (Light Green/Black wire) between CPP switch harness connector and terminal No. 23 at PCM C1 harness connector. See Figure . If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or more, repair open in Light Green/Black wire.
  6. Connect a test light between battery positive and ground circuit (Black wire) at CPP switch harness connector. If test light illuminates brightly, go to next step. If test light does not illuminate brightly, repair open in ground circuit between CPP switch harness connector and ground point located in left front of engine compartment, on top of core support.
  7. If no other possible causes are remaining, replace PCM.
