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). P0833 is the general fault of switch B; on Ford it means the switch is stuck low. GM's 2006 manual cars (Corvette, CTS-V, GTO, SSR, Trailblazer SS) require the switch to change state at least once during a drive from standstill to over 39 km/h and back; if it does not, 9 of 10 samples of 100 ms set the code, type B with the MIL after two trips. Cruise control then cannot be activated.

Likely causes

Switch misadjusted (no longer actuated or released)
Switch faulty
Wire or connector open
Pedal stop or bumper worn
