P0835 — Clutch pedal switch circuit signal is too high

The code indicates an electrical issue with the clutch pedal switch circuit, usually meaning the switch is sending a high voltage signal or is not working properly. This switch tells the car when the clutch pedal is pressed, which is important for starting the engine or shifting gears in some vehicles.

Common causes

The cause is almost always one of a few things. Here they are — P0835 rarely comes from anything outside this list:

• Faulty or misaligned clutch pedal switch
• Damaged or corroded wiring/connectors in switch circuit
• Short circuit or open circuit in clutch switch wiring
• Faulty clutch pedal switch connector
• Malfunctioning vehicle control module (rare)

Where to start

In the order a sensible mechanic would work — the cheap checks first, the expensive replacements only after:

1. Inspect and clean clutch pedal switch connector
2. Check wiring for damage or corrosion and repair
3. Test clutch pedal switch operation and alignment
4. Replace faulty clutch pedal switch if needed
5. Scan and reset vehicle control module codes

That is what holds for P0835 in general. From here it depends on your engine — tell me which car it is and what it does, and I will give you the steps for it: real procedures, torque figures and diagrams instead of general advice.
