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.
