What Does P0835 Mean?
The PCM has detected a high voltage condition on the clutch pedal position switch "B" circuit. This indicates the signal line is stuck high, which may be caused by an open circuit, a switch stuck in the open position, or a short to battery voltage in the wiring. The clutch pedal state cannot be reliably determined.
Common Causes
40%
Faulty clutch pedal position switch "B" stuck open
25%
Open circuit in switch wiring harness
15%
Short to battery voltage in signal wire
15%
Corroded or disconnected connector at switch or PCM
5%
PCM/TCM internal fault
Diagnostic Steps
1
Read freeze frame data to determine the conditions under which the code was set and note the switch B voltage value.
2
Visually inspect the clutch pedal position switch B and its connector for physical damage, disconnection, or corrosion.
3
With the switch connector plugged in, back-probe the signal wire and verify voltage drops when the clutch pedal is depressed; a constant high voltage indicates a stuck or open circuit.
4
Disconnect the switch and check for a short to battery voltage on the signal wire using a multimeter.
5
Test the switch independently for proper continuity changes with pedal actuation; replace if faulty.
6
If wiring checks pass, inspect the PCM connector pins for the switch B input.

The most common cause of P0835 (Clutch Pedal Switch "B" Circuit High) is: Faulty clutch pedal position switch "B" stuck open
Typical repair costs for P0835 range from $50 to $250, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Cruise control may not disengage when the clutch pedal is pressed, and starter interlock may be affected. Avoid using cruise control and have the vehicle inspected soon.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P0835 to identify the root cause.
