Technical Description of OBD-II Trouble Code
The circuit for Clutch Pedal Switch A is experiencing high voltage.
What does that mean?
This generic powertrain diagnostic trouble code (DTC) typically applies to all OBD-II vehicles equipped with a clutch pedal. This includes vehicles from various manufacturers such as Jaguar, Dodge, Chrysler, Chevy, Saturn, Pontiac, Vauxhall, Ford, Cadillac, GMC, Nissan, etc. Although it is a generic code, the specific repair steps may vary depending on the make and model of the vehicle.
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, which is also known as the clutch position sensor or clutch start switch circuit, it can set a number of different codes.
These codes include P0830, P0831, P0832, P0833, P0834, P0835, and P083F, depending on the specific malfunction that triggers the PCM to set the code and illuminate the Check Engine Light.
The purpose of the Clutch Pedal Switch “A” Circuit is for the PCM to monitor the position of the clutch pedal. This is done by reading the output voltage of the clutch position sensor. The design of the clutch position sensor switch may vary from one vehicle to another, but it is typically a basic “on/off” switch mounted near the clutch foot pedal on the support bracket. Regardless of the design, there is usually constant voltage present on one side of the switch, and the contacts are closed by engaging the clutch pedal, which transfers voltage to the starter or starter solenoid. This basic circuit and switch prevent the engine from starting before the clutch is engaged.
Code P0832 Clutch Pedal Switch A Circuit High is set by the PCM when the Clutch Pedal Switch “A” Circuit experiences a high voltage situation.
What is the severity of this DTC?
The severity of this code is typically 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:

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, 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.
Advanced Steps
The advanced steps become very vehicle specific and require the appropriate advanced equipment to perform accurately. These procedures require a digital multimeter and the specific technical references for the vehicle. Voltage requirements will vary based on the specific year and model of the vehicle.
Voltage Checks
When the clutch is disengaged, there should be approximately 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?
Common Mistakes
Replacing the starter or the solenoid when the problem lies with the clutch position sensor, damaged wiring, or a defective connector.
