DTC P0833 8.1L
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. |

DTC P0833 6.6L
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 engine control module (ECM) detects a large number of gear changes without detecting a clutch switch transition, DTC P0833 sets. DTC P0833 is a type C 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 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. |
