P0834 code meaning
Clutch Pedal Switch B Circuit Low
What P0834 means
Clutch pedal switches A and B are digital inputs of manual gearboxes: they release the starter only with the pedal pressed, switch off cruise control and tell start-stop whether the clutch is open. Which switch is A or B is up to each manufacturer – FCA calls the pedal-up switch A. Ford's 2020–23 summary checks a dual switch over more than 40 pedal applications and reports a stuck switch without MIL (P0830 stuck high, P0833 stuck low, comparison P0704). P0834 means switch B stays at ground – a short to ground or an open supply. No manufacturer document available to us uses it: GM's 2006 tables check switch B only for plausibility (P0833), and Ford reports a switch stuck low under P0833. The effects match P0833.

What each part of P0834 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |

| 34 | The exact fault in that area. |
What to do next
- Note P0834 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
