OBD-II Code
P0833
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)
$110–$360
From this code's diagnostic notes. Varies by vehicle, diagnosis, parts, and local labor. This is not a repair quote.
P0833 is the lower clutch pedal position switch B fault, typically the bottom-of-travel switch used to confirm full disengagement for shift-lock release, hill-start hold, and on dual-clutch and AMT vehicles, the launch authorization logic.
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.

Cheapest diagnostic path
scan-tool the switch state while a helper presses the pedal slowly to the floor and watch for a clean transition near the bottom 15-20 percent of travel; the B switch should go from open to closed within the final inch of pedal stroke. Ohm-check the switch with the connector unplugged: spec is under 2 ohms closed at the floor and over 50 kilohms open at rest. Caveat: on DCT and AMT cars the B switch is a safety interlock, so the TCM may refuse all gear engagement when P0833 is active even if mechanical clutch action is normal.

- 2011-2014Ford Mustang GT 6-speed manual has a known striker-tab break that throws P0833 with no apparent symptom until cruise disengages.
- 2013-2019Chevrolet Cruze and Sonic manuals have an integrated upper/lower switch assembly where the B contact fails first.
- 2015-2020Subaru WRX 6-speed manual sees P0833 from a switch that loosens on its slotted mount after aggressive heel-toe footwork.
