OBD-II Trouble Code Technical Description

Clutch Pedal Switch A Circuit High
What does that mean?
This generic powertrain diagnostic trouble code (DTC) typically applies to all OBD-II vehicles equipped with a clutch pedal. That may include but is not limited to vehicles from Jaguar, Dodge, Chrysler, Chevy, Saturn, Pontiac, Vauxhall, Ford, Cadillac, GMC, Nissan, etc. Although generic, the specific repair steps may vary depending on make/model.
The P0832 OBD-II trouble code is associated with the Clutch Pedal Switch "A" Circuit. When the Powertrain Control Module (PCM) detects a malfunction within the Clutch Pedal Switch "A" Circuit, also known as the clutch position sensor or clutch start switch circuit a number of different codes can be set.
The purpose of the Clutch Pedal Switch "A" Circuit is for the PCM to monitor the position of the clutch pedal. This process is accomplished by reading the output voltage of the clutch position sensor. The clutch position sensor switch may vary in design from one vehicle to another, it is usually a basic "on/off" switch mounted near the clutch foot pedal on the support bracket. Regardless of the design, constant voltage is typically present on one side of the switch and the contacts are closed by engaging the clutch pedal transferring voltage to the starter or starter solenoid. This basic circuit and switch prevents starting the engine prior to engaging the clutch.
Code P0832 Clutch Pedal Switch A Circuit High is set by the PCM when the Clutch Pedal Switch "A" Circuit is experiencing a high voltage situation.
What is the severity of this DTC?
The severity of this code is normally moderate, but it can be severe if the vehicle starts with the clutch disengaged creating a safety issue.
What are some of the symptoms of the code?
Symptoms of a P0832 engine code may include:
- The engine will not start
- The engine will start without engaging the clutch
- Check Engine Light illuminated
What are some of the possible causes of the code?
Causes for this code may include:
- Faulty clutch position sensor switch
- Blown fuse or fuse-able link (if applicable)
- Corroded or damaged connector
- Faulty or damaged wiring
- Faulty PCM
What are some P0832 troubleshooting steps?
The first step in the troubleshooting process for any malfunction is to research the Technical Service Bulletins (TSB's) for the specific vehicle by year, model and power plant. In some circumstances this can save a lot of time in the long run by pointing you in the right direction.
The second step is to locate the clutch position sensor switch and look for obvious physical damage. Perform a thorough visual inspection to check the associated wiring for obvious defects such as scraping, rubbing, bare wires, or burn spots. Next is to check the connectors and connections for security, corrosion and damaged pins. This process must include all wiring connectors and connections to the clutch position sensor switch, PCM, starter and the starter solenoid. Consult the specific tech data for the vehicle to see if a fuse or fuse-able link is incorporated into the circuit.
The advanced steps become very vehicle specific and require the appropriate advanced equipment to perform accurately. These procedures require a digital multi meter and the specific technical references for the vehicle. Voltage requirements will very based of the specific year and model of the vehicle.
When the clutch is disengaged there should be appropriately 12 volts on one side of the switch. When the clutch is engaged you should have voltage on both sides of the switch. The starter solenoid or starter should also have power based on the configuration.
If this process identifies the absence of a power source or ground, continuity testing may be required to check the integrity of the wiring and the clutch position sensor switch.
When the clutch is engaged you should have continuity through the switch and when the clutch is released the meter should indicate no continuity through the switch. Continuity tests should always be performed with the power removed from the circuit and the normal readings for wiring and connections should be 0 ohms of resistance unless otherwise specified by the technical data. Resistance or no continuity is an indication of faulty wiring that is open or shorted and must be repaired or replaced.
What Are Some Common Repairs?
- Replacing the clutch position sensor
- Replacing blown fuse or fuse-able link (if applicable)
- Cleaning corrosion from connectors
- Repairing or replacing wiring
- Flashing or replacing PCM
Replacing the starter or the solenoid when the clutch position sensor, damaged wiring or a defective connector is the problem.
Hopefully, the information in this article has been helpful to point you in the right direction to correct the problem with your Clutch Pedal Switch "A" Circuit fault code. This article is strictly informational and the specific technical data and service bulletins for your vehicle should always take priority.
