The engine symbol on the speedometer lit up on Thursday. I plugged in my code reader and I had 2 entries for code P0833. In my book that code means "Clutch Pedal Switch "B" Circuit". I assume I need to take it in for service. Can anyone tell me what this means or are there multiple possibilities?

Thanks for sharing your knowlege

 

From my service manual:



Circuit Description
Battery voltage is supplied from the Engine Ignition 1 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.

If the engine control module (ECM) detects a specified number of vehicle speed transitions 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 vehicle speed goes from 0 km/h (0 mph) to greater than 39 km/h (24 mph) and back to 0 km/h (0 mph) for 2 seconds without the ECM detecting a clutch transition.
This must occur 7 times before the diagnostic reports a fault.
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.
Cruise control is disabled.
The ECM records the operating conditions at the time 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.
Conditions for Clearing the MIL/DTC
The ECM 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 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 fault no longer exists and the DTC passes.
Diagnostic Aids

Important
Remove any debris from the ECM connector surfaces before servicing the ECM. Inspect the ECM connector gaskets when diagnosing/replacing the module. Ensure that the gaskets are installed correctly. The gaskets prevent contaminate intrusion into the ECM.
For any test that requires probing the ECM or a component harness connector, use the J 35616-C GM terminal test kit. Using this kit prevents damage to the harness/component terminals. Refer to Using Connector Test Adapters in Wiring Systems.

For clutch switch adjustment refer to Clutch Pedal Position Switch Replacement in Clutch.

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.

This step tests for a short to ground.

This step tests for voltage to the fuse.

This step tests the clutch pedal position switch.

This step tests the Clutch Pedal Position switch signal circuit.

This step tests the Ignition 1 Voltage circuit for a short to ground.

This step tests the Clutch Pedal Position switch signal circuit for a ground.

This step ensures that the technician has verified the system is operating normally.

I'm curious as to why people own code readers if they don't know what the codes mean or what to do about them. This is not meant as a poke but simply just curiosity. where would you even get a code reader?

By the way, the underlying falls under the category of "take it in to the dealer"

 

Many folks own code readers so they can diagnose and turn off nuiscance check engine lights (like the gas cap caused one for instance). Coming from the C5 my only dissapointment in the C6 is in the fact that I could not get at the codes via the DIC like I could in the C5. You now require a CAN capable OBDII Scantool. They can be purchased relatively inexpensively

http://www.diydiagnostics.com/index2.html

and in many cases can save you a trip to the dealer or provide peace of mind. Additionally, since it is not limited to working on the Corvette many have them but do not know the specifics for the Corvette yet as they may for another vehicle that they own.

You don't need a code reader to check you gas cap. If the light comes on, the first thing to do is check the cap. If the light goes off, you'll know you were right. If it doesn't, time for a trip to the dealer. No code reader needed.

 

From the service manual:

"If the engine control module (ECM) detects a specified number of vehicle speed transitions without detecting a clutch switch transition, DTC P0833 is set." To wit: Yer clutch pedal switch/circuit possibly ain't working...maybe it's out of adjustment, or maybe it's just broke.

 

Your opinion

p.s. If you knew the answer, why did you ask the question?

 

Where GM will pay the tech .3 labor hours (18 minutes) diagnoses time to perform steps 1-18

 

Thanks Talon90 for taking the time to type in all the information.

 

that's funny becasue it's true

 

Just curious as to your version.
