Circuit Description
The clutch switch is a normally closed switch, clutch pedal released. The engine control module (ECM) detects an ignition voltage on the clutch switch circuit when the clutch switch is closed. The ECM detects 0 volts on the clutch switch circuit when the clutch switch is open, clutch pedal depressed.
When the ECM 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 DTCs P0721 or P0722. |
| • | The vehicle speed is greater than 15 km/h (9 mph). |
| • | The brake switch remains released. |
Conditions for Setting the DTC
| • | The ECM must detect 20 or more gear changes with less than 6 clutch pedal transitions. |
| • | Time between gear changes must be 4 seconds or greater. |
Action Taken When the DTC Sets
| • | The ECM illuminates the malfunction indicator lamp (MIL) during the second consecutive trip in which the Conditions for Setting the DTC are met. |
| • | The ECM disables Cruise Control. |
| • | The ECM records the operating conditions when the Conditions for Setting the DTC are met. The ECM stores this information as Freeze Frame and Failure Records. |
| • | The ECM stores DTC P0833 in ECM History during the second consecutive trip in which the Conditions for Setting the DTC are met. |
Conditions for Clearing the MIL/DTC
| • | The ECM turns OFF the MIL during the third consecutive trip in which the diagnostic runs and passes. |
| • | A scan tool can clear the MIL/DTC. |
| • | The ECM clears the DTC from ECM history if the vehicle completes 40 warm-up cycles without an 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. |
Test Description
The number below refers to the step number 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 | Values | Yes | No |
|---|---|---|---|---|
1 | Did you perform the Diagnostic System Check - Vehicle? | -- | Go to Step 2 | Go to Diagnostic System Check - Vehicle in Vehicle DTC Information |
Does the scan tool indicate a change in state when the clutch pedal is either applied or released? | -- | Go to Intermittent Conditions in Engine Controls - 2.8L or Intermittent Conditions in Engine Controls - 3.6L | Go to Step 3 | |
Inspect the adjustment of the clutch pedal position switch and the connector. Does the clutch switch require adjustment or the connector require service? | -- | Go to Step 11 | Go to Step 4 | |
4 | Inspect the HTR VLV/CLTCH fuse for an open. Refer to Circuit Protection - Fuses in Wiring Systems. Is the HTR VLV/CLTCH fuse open? | -- | Go to Step 9 | Go to Step 5 |
5 | Using a DMM, measure voltage at the HTR VLV/CLTCH 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 HTR VLV/CLTCH 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. Refer to Wiring Repairs . 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. Refer to Wiring Repairs . Did you complete the repair? | -- | Go to Step 17 | -- |
15 | Replace the clutch pedal position switch. Refer to Clutch Pedal Position Switch Replacement in Clutch. Is the action complete? | -- | Go to Step 17 | -- |
16 | Replace the ECM. Refer to Control Module References in Computer/Integrating Systems 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? | -- | Go to Diagnostic Trouble Code (DTC) List - Vehicle in Vehicle DTC Information | System OK |
