Circuit Description
Battery voltage is supplied from the clutch brake 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.
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 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 DTCs P0502 or P0503.
Conditions for Setting the DTC
The PCM detects 7 changes in vehicle speed 0- 38 km/h (0-24 mph) without the PCM detecting a clutch pedal transition.
Action Taken When the DTC Sets
| • | The PCM does not illuminate the malfunction indicator lamp (MIL). |
| • | 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 Failure Records. |
| • | The PCM stores DTC P0833 in PCM history. |
Conditions for Clearing the DTC
| • | A scan tool can clear the DTC. |
| • | The PCM clears the DTC from PCM history if the vehicle completes 40 warm-up cycles without a non-emission related diagnostic fault occurring. |
| • | The PCM cancels the DTC default actions when the fault no longer exists and the DTC passes. |
Test Description
The numbers below refer to the step numbers on the diagnostic table.
-
This test confirms if the scan tool is receiving a clutch switch position signal.
-
This step inspects the clutch pedal connector and adjustment.
Step | Action | Value(s) | Yes | No |
|---|---|---|---|---|
1 | Did you perform the Diagnostic System Check - Vehicle? | -- | Go to Step 2 | |
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. Does the scan tool indicate a change in state when the clutch pedal is either applied or released? | -- | Go to Testing for Intermittent Conditions and Poor Connections | Go to Step 3 | |
Inspect the adjustment of the clutch pedal position switch and the connector. Refer to Clutch Pedal Position Switch Adjustment . Does the clutch switch require adjustment or the connector require service? | -- | Go to Step 11 | Go to Step 4 | |
4 | Inspect the EMISN fuse for an open. Refer to Circuit Protection - Fuses . Is the Clutch/Brake fuse open? | -- | Go to Step 9 | Go to Step 5 |
5 | Using a DMM, measure voltage at the brake fuse. Does the DMM indicate the specified value? | B+ | Go to Step 6 | Go to Step 12 |
6 |
Does the DMM indicate the specified value? | B+ | Go to Step 7 | Go to Step 13 |
7 |
Does the scan tool display that the clutch is applying and releasing? | -- | Go to Step 15 | Go to Step 8 |
8 |
Did you find a short to voltage, high resistance or an open on the clutch pedal position switch signal circuit? | -- | Go to Step 14 | Go to Step 16 |
9 |
Is the ignition 1 voltage circuit grounded? | -- | Go to Step 13 | Go to Step 10 |
10 | Using a DMM, test for a short to ground on the clutch pedal position switch signal circuit at the switch connector. Is the clutch pedal position switch signal circuit grounded? | -- | Go to Step 14 | Go to Step 15 |
11 | Adjust the clutch pedal position switch or repair the connector as necessary. Did you complete the repair? | -- | Go to Step 17 | -- |
12 | Repair the power distribution circuit to the brake fuse. Did you complete the repair? | -- | Go to Step 17 | -- |
13 | Repair the open, high resistance or short to ground in the ignition 1 voltage circuit or a parallel circuit that uses the brake fuse. Did you complete the repair? | -- | Go to Step 17 | -- |
14 | Repair the open, high resistance, short to ground, or short to voltage in the clutch pedal position switch signal circuit. Did you complete the repair? | -- | Go to Step 17 | -- |
15 | Replace the clutch pedal position switch. Refer to Clutch Pedal Position Switch Replacement . Is the action complete? | -- | Go to Step 17 | -- |
16 | Replace the PCM. Refer to Control Module References for replacement, setup, and programming. Is the action complete? | -- | Go to Step 17 | -- |
17 |
Has the test run and passed? | -- | Go to Step 18 | Go to Step 2 |
18 | With the scan tool, observe the stored information, capture info and DTC info. Does the scan tool display any DTCs that you have not diagnosed? | -- | System OK |
