Circuit Description

Battery voltage is supplied from the engine ignition 1 fuse to the clutch switch. The clutch switch is a normally closed switch. When the clutch pedal is released, the clutch pedal position switch signal circuit is pulled up to B+. When the clutch pedal is applied, the switch opens, and the voltage drops to 0 volts.

If the powertrain control module (PCM) detects a specified number of vehicle speed transitions without detecting a clutch switch transition, DTC P0833 sets. DTC P0833 is a type B DTC.

DTC Descriptor

This diagnostic procedure supports the following DTC:

DTC P0833 Clutch Pedal Switch 2 Circuit

Conditions for Running the DTC

No VSS DTC P0500.

Conditions for Setting the DTC
    • The vehicle speed goes from 0 km/h (0 mph) to greater than 39 km/h (24 mph) and back to 0 km/h (0 mph) for 2 seconds without the PCM detecting a clutch transition.
    • This must occur 7 times before the diagnostic reports a fault.

Action Taken When the DTC Sets
    • The PCM illuminates the malfunction indicator lamp (MIL) during the second consecutive trip in which the Conditions for Setting the DTC are met.
    • The PCM disables cruise control.
    • The PCM records the operating conditions when the Conditions for Setting the DTC are met. The PCM stores this information as Freeze Frame and Failure Records.
    • The PCM stores DTC P0833 in PCM history.

Conditions for Clearing the MIL/DTC
    • The PCM turns OFF the MIL during the third consecutive trip in which the diagnostic test runs and passes.
    • A scan tool can clear the MIL/DTC.
    • The PCM clears the DTC from PCM history if the vehicle completes 40 warm-up cycles without an emission-related diagnostic fault occurring.
    • The PCM cancels the DTC default actions when the fault no longer exists and the DTC passes.

Diagnostic Aids

Important: 

   • Remove any debris from the PCM connector surfaces before servicing the PCM. Inspect the PCM connector gaskets when diagnosing/replacing the module. Ensure that the gaskets are installed correctly. The gaskets prevent contaminate intrusion into the PCM.
   • For any test that requires probing the PCM or a component harness connector, use the J 35616 GM terminal test kit. Using this kit prevents damage to the harness/component terminals. Refer to Using Connector Test Adapters in Wiring Systems.

For clutch switch adjustment refer to Clutch Pedal Position Switch Replacement in Clutch.

Test Description

The numbers below refer to the step numbers on the diagnostic table.

  1. This step ensures that the technician has performed a diagnostic system check.

  2. This test confirms if the scan tool is receiving a clutch switch position signal.

  3. This step inspects the clutch pedal connector and adjustment.

  4. This step tests for a short to ground.

  5. This step tests for voltage to the fuse.

  6. This step tests for voltage to the clutch pedal position switch.

  7. This step tests the clutch pedal position switch.

  8. This step tests the clutch pedal position switch signal circuit.

  9. This step tests the ignition 1 voltage circuit for a short to ground.

  10. This step tests the clutch pedal position switch signal circuit for a ground.

  11. This step ensures that the technician has verified the system is operating normally.
