OBD-II Code
P0835
Severity
Not yet reviewed
Nobody on our side has assessed this code yet, so we are not going to guess at how serious it is.
Can you drive it
We cannot say
Treat it as unknown until a shop reads it with live data. If the check-engine light is FLASHING, stop driving as soon as it is safe to — that means an active misfire, whatever the code.
Indicative cost (USD)
$35–$250
From this code's diagnostic notes. Varies by vehicle, diagnosis, parts, and local labor. This is not a repair quote.
P0835 sets when the PCM sees the Clutch Pedal Position Switch A signal staying inside an implausible voltage range — not fully open (0V) and not fully closed (battery V), but stuck somewhere in the middle, or transitioning so slowly that the PCM cannot determine pedal state.
How a shop works this
Work from evidence to part, not the other way round. A code names a circuit or a symptom; it does not name the part that failed.
Note every code that is set, not just this one.
Codes that appear together usually narrow the cause faster than any one of them read alone.
Read the freeze frame — the conditions the fault was recorded under.
Cold or warm, idle or load, road speed and engine speed. A fault that only appears cold is a different fault from one that only appears under load, even with the same code on the scanner.
Confirm the fault is current rather than history.
Clear the code and see whether it returns under those same conditions. A code that does not come back may have been logged during a repair, a flat battery, or a bad connection that has since been disturbed.
Then follow the diagnostic notes further down this page, in the order they are written.
They are written in the order a shop works this code, cheapest checks first. Where they name a component, inspect its wiring and connector before replacing it.
If the code comes back after a repair, the underlying fault is still there. That is the point to bring in a scanner with live data and freeze-frame, or a shop that has one.

P0835 sets when the PCM sees the Clutch Pedal Position Switch A signal staying inside an implausible voltage range — not fully open (0V) and not fully closed (battery V), but stuck somewhere in the middle, or transitioning so slowly that the PCM cannot determine pedal state. On a typical Ford or Honda manual the CPS A signal should snap from 0V to ~12-14V in under 100ms when the pedal is pressed; a signal that ramps slowly or hangs at 6-7V is a switch with pitted contacts arcing across the gap.
Cheapest-first ladder
- Backprobe the A-switch signal wire with a DMM in min/max mode and cycle the pedal ten times — record both extremes; anything that reads between 1V and 10V at either steady-state position is a failing switch.
- Use a scope if available; the rising and falling edges should be near-vertical, not a slow ramp. A slow edge means the contacts are arcing and welding microscopically each cycle.
- Inspect the pedal-bracket geometry — a bent bracket holds the switch plunger partially depressed at rest, putting the contacts in the arc zone. Expensive-misdiagnosis caveat: P0835 is the code that catches the half-failed switch that P0830 misses, and a shop that clears the code without verifying the switch waveform will see the customer back inside a week; the right move is replacing the switch the first time, not chasing PCM or wiring intermittents.
