P0833 Clutch Pedal Switch B Circuit
OBD-II Trouble Code Technical Description
Clutch Pedal Switch B Circuit
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 P0833 OBD-II trouble code is associated with the Clutch Pedal Switch "B" Circuit. When the Powertrain Control Module (PCM) detects a malfunction within the Clutch Pedal Switch "B" Circuit, also known as the clutch position sensor or clutch start switch circuit a number of different codes can be set.
These codes are P0830, P0831, P0832, P0833, P0834, P0835 and P083F based on the specific malfunction that alerts the PCM to set the code and illuminate the Check Engine Light.
The purpose of the Clutch Pedal Switch "B" 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 P0833 Clutch Pedal Switch B Circuit is set by the PCM when the Clutch Pedal Switch "B" Circuit is open or has a general malfunction. Refer to a vehicle specific repair manual to determine which is the "B" circuit for your particular vehicle.
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 P0833 engine code may include:
The engine will not start The engine will start without engaging the clutch Check Engine Light illuminatedWhat 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 PCMWhat are some P0833 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.
Advanced Steps
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.
