Circuit Description

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

When the powertrain control module (PCM) detects a large number of gear changes 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 PCM detects 7 changes in vehicle speed greater than 38 km/h (24 mph) without the PCM detecting a clutch pedal transition.

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 disables power take-off.
    • 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 during the second consecutive trip in which the Conditions for Setting the DTC are met.

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 ignition switch is OFF long enough in order to power down the PCM.

  1. Install a scan tool.
  2. Turn ON the ignition, with the engine OFF.
  3. Important: Before clearing the DTCs use the scan tool in order to record the Freeze Frame and Failure Records for reference. The Clear Info function will erase the data.

  4. Use the scan tool to monitor the clutch pedal position switch parameter.
  5. Apply and release the clutch pedal several times.

Does the scan tool indicate a change in state when the clutch pedal is either applied or released?

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 ECM detects 7 changes in vehicle speed from 0 km/h (0 mph) to above 38 km/h (24 mph) and then back to 0 km/h (0 mph) without the ECM detecting a clutch pedal transition.

Action Taken When the DTC Sets

    •  The ECM does not illuminate the malfunction indicator lamp (MIL).
    • The ECM disables cruise control.
    • The ECM disables power take-off.
    • The ECM records the operating conditions when the Conditions for Setting the DTC are met. The ECM stores this information as Failure Records.
    • The ECM stores DTC P0833 in ECM history.

Conditions for Clearing the DTC

    • A scan tool can clear the DTC.
    • The ECM clears the DTC from ECM history if the vehicle completes 40 warm-up cycles without a non-emission-related diagnostic fault occurring.
    • The ECM cancels the DTC default actions when the ignition switch is OFF long enough in order to power down the ECM.
