What Does P0833 Mean?
The clutch pedal switch "B" circuit has a general malfunction. Many vehicles use two clutch switches — "A" for the starting interlock and "B" as a redundant input or for cruise control and transmission shift logic. A fault on the "B" switch circuit means the secondary clutch position signal is unreliable, affecting systems that rely on this input.
Common Causes

10%
Broken or missing switch bumper pad for switch B
10%
PCM/BCM input circuit failure for clutch switch B signal
Diagnostic Steps
1
Monitor clutch pedal switch B status in live data while operating the clutch pedal — verify it toggles correctly between pressed and released states.
2
Locate the "B" clutch switch (often a separate switch from the "A" switch at the pedal assembly) and inspect for proper mounting and adjustment.
3
Check for a missing or deteriorated switch actuator bumper pad that controls when the switch activates.
4
Test the switch for proper open/closed operation with a multimeter.
5
Verify wiring integrity from the switch to the PCM/BCM, checking for continuity, voltage supply, and ground.

Typical repair costs for P0833 range from $25 to $200, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Cruise control may not disengage when the clutch is pressed, which is a safety concern on the highway. Some automated manual transmissions may also shift incorrectly. The vehicle is drivable but avoid using cruise control until repaired.
