P0835

Clutch Pedal Switch B Circuit High

Q: Is it safe to drive with P0835?

Yes. The engine and transmission still work normally; the switch mainly affects cruise control and shift indicators, and on some cars the clutch-start interlock.

Q: Can I just clear P0835?

You can, but it returns the next time the clutch switch is read until the switch or its wiring is repaired.

Transmission / clutch switch Generic OBD-II Low

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.

Low

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.
