Clutch Pedal Switch B Circuit High
What it means
P0835 sets when the clutch pedal switch "B" circuit reads a high (open-circuit) voltage. This manual-transmission switch tells the controller whether the clutch pedal is pressed, and its signal is used for things like cruise-control cancellation, shift indicators, and — on some vehicles — the clutch-start interlock. It's a minor electrical fault: the engine runs and the car drives normally, though cruise control may not engage.
Can I keep driving? Safe to drive; you may notice cruise control won't set, and on some vehicles the engine only cranks with the clutch fully pressed.

How to diagnose & fix
Work through it in order
- Confirm the code and check for companion codes (P0833, P0834).
- Inspect and adjust the clutch pedal switch; verify it changes state through full pedal travel.
- Check the wiring and connector for opens, corrosion, or a pushed-out pin.
- Replace the clutch pedal switch if it doesn't switch cleanly.
- Clear the code and retest by cycling the clutch pedal.
