Test Description

WARNING: This page is about a different car, the 2004 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.

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

  1. 1:  This step ensures that the technician has performed a Diagnostic System Check on the Manual Transmission System.
  2. 2:  This test confirms if the scan tool is receiving a clutch switch position signal.
  3. 3:  This step inspects the clutch pedal connector and adjustment.
  4. 4:  This step tests for a short to ground.
  5. 5:  This step tests for voltage to the fuse.
  6. 6:  This step tests for voltage to the clutch pedal position switch.
  7. 7:  This step tests the clutch pedal position switch.
  8. 8:  This step tests the Clutch Pedal Position switch signal circuit.
  9. 9:  This step tests the Ignition 1 Voltage circuit for a short to ground.
  10. 10:  This step tests the Clutch Pedal Position switch signal circuit for a ground.
  11. 17:  This step ensures that the technician has verified the system is operating normally.
DTC P0833

Step Action Values Yes No
1  Did you perform the Diagnostic System Check - Engine Controls? - Go to Step 2  Go to Diagnostic System Check - Engine Controls in Engine Controls - 5.7L
2 
  1. Install a scan tool.
  2. Turn ON the ignition, with the engine OFF.
  3. Use the scan tool to monitor the clutch pedal position switch parameter.
  4. 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?		 - Go to Intermittent Conditions in Engine Controls - 5.7L Go to Step 3 
3  Inspect the adjustment of the clutch pedal position switch and the connector. Refer to Clutch Pedal Cruise Control Release Switch Replacement in Cruise Control.
Does the clutch switch require adjustment or the connector require service?		 - Go to Step 11  Go to Step 4 
4  Is the Engine Ignition 1 fuse open? - Go to Step 9  Go to Step 5 
5 
  1. Start the vehicle.
  2. Using a DMM, measure voltage at the Engine Ignition 1 fuse in the underhood fuse block.
Does the DMM indicate the specified value?		 B+ Go to Step 6  Go to Step 12 
6 
  1. Turn OFF the ignition.
  2. Disconnect the clutch pedal position switch connector.
  3. Start the vehicle.
  4. Using a DMM, measure the voltage at the Ignition 1 Voltage circuit.
Does the DMM indicate the specified value?		 B+ Go to Step 7  Go to Step 13 
7 
  1. Use the scan tool to monitor the clutch pedal position switch parameter.
  2. Put the transmission in Neutral.
  3. Apply the parking brake.
  4. Start the vehicle.
  5. Use a fused jumper wire to repeatedly connect and disconnect pin A and pin B of the clutch pedal position switch electrical connector.
Does the scan tool parameter display applied and released?		 - Go to Step 15  Go to Step 8 
8 
  1. Turn the ignition switch OFF.
  2. Disconnect C1 at the PCM.
  3. Using the DMM, test for continuity and a short to voltage on the Clutch Pedal Position switch signal circuit.
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 
  1. Turn the ignition switch OFF.
  2. Remove the Engine Ignition 1 fuse.
  3. Disconnect the clutch pedal position switch connector and C1 at the PCM.
  4. Using a DMM, test for a short to ground on the Ignition 1 Voltage circuit at the switch connector.
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. Refer to Clutch Pedal Cruise Control Release Switch Replacement in Cruise Control.
Did you complete the repair?		 - Go to Step 17  -
12
IMPORTANT: Voltage to this fuse is run through the Ignition relay. Refer to Power Distribution Schematics in Wiring Systems.
Repair the Power Distribution circuit to the Engine Ignition 1 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 fuse.
Did you complete the repair?		 - Go to Step 17  -
14 Repair the open, high resistance or short 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 in Clutch.
Is the action complete?		 - Go to Step 17  -
16 Replace the PCM. Refer to Powertrain Control Module (PCM) Replacement in Engine Controls - 5.7L.
Is the action complete?		 - Go to Step 17  -
17  Perform the following procedure in order to verify the repair:
  1. Select DTC.
  2. Select Clear Info.
  3. Operate the vehicle from 0 km/h (0 mph) to above 38 km/h (24 mph) then back to 0 km/h (0 mph) 7 times.
  4. Select Specific DTC.
  5. Enter DTC P0833.

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 in Engine Controls - 5.7L System OK
