P0833
Clutch Pedal Switch B Circuit
Transmission
Generic OBD-II
Medium
What it means
P0833 means the module sees a fault in the 'B' clutch-pedal switch circuit on a manual-transmission car. That switch tells the computer whether the clutch is pressed, which controls the clutch-start interlock and features like cruise control. The engine and transmission are mechanically fine — the issue is usually a bad switch, its adjustment, or the wiring.
Medium
Can I keep driving? The car drives normally once running, but a faulty clutch switch can stop the engine from cranking (the clutch-start interlock) or disable cruise control.

How to diagnose & fix
Work through it in order
- Locate the clutch pedal switch and check its connector for damage, corrosion, or a loose fit.
- Test the switch for correct open/closed operation as the pedal is pressed and released.
- Inspect and repair the wiring between the switch and the control module.
- Confirm the switch is properly adjusted to the pedal; replace the switch if it fails testing.
- Clear the code and confirm normal crank and cruise-control behaviour.
FAQ
Quick answers
Is it safe to drive with P0833?+
Yes — this is a switch/circuit fault, not a mechanical one. The main annoyances are a possible no-crank until the pedal is pressed and loss of cruise control.
Can I just clear P0833?+
You can, but it returns until the switch, its adjustment, or the wiring is repaired.
