Fuel level sensor A (typically the float in the main fuel tank section) reports a value that does not change o…
Same condition as sensor A stuck, applied to the second fuel level sensor B. Saddle tanks (often AWD vehicles)…
The ECM detects that one of the two level sensors is stuck but cannot identify which from the available signal…
Wastegate A is mechanically stuck open. Exhaust gas bypasses the turbine even at low load — turbo cannot reach…
Wastegate A is mechanically stuck closed. The turbo cannot bleed off exhaust at high load — boost overshoots t…
Same as wastegate A stuck open, applied to the second wastegate (twin-turbo, sequential or two-stage). Boost c…
Same as wastegate A stuck closed, applied to the second wastegate. Boost control tracks commanded vs. actual m…

Auxiliary ignition switch On/Start input reads stuck low — short to ground or stuck-closed contact. Wiring fau…
Auxiliary ignition switch On/Start input reads stuck high — short to battery voltage. Wiring faults of this ki…
The DPF/SCR forced-regeneration request switch — used on commercial vehicles to let the operator force a parke…
Regeneration control switch input reads stuck low — short to ground or stuck-closed contact. The ECM may see a…
Regeneration control switch input reads stuck high — short to battery voltage. Wiring faults of this kind typi…
The engine controller commanded a forced shutdown after detecting unmetered fuel reaching the combustion chamb…
The controller cannot drive the alternative-fuel disable line that switches a bi-fuel vehicle (CNG, LPG, hydro…
Voltage on the alternative-fuel disable control line is above the expected window. Often a short to battery up…
Voltage on the alternative-fuel disable control line is below the expected window. Usually a short to ground o…
The feedback signal that confirms the alt-fuel disable command was carried out is missing or out of range. The…
The disable feedback signal sits above its valid window. Typical cause is a short to battery on the feedback w…
The disable feedback signal sits below its valid window. Usually a short to ground or an open pull-up that let…
The temperature sensor monitoring the electric brake booster (iBooster, eBooster) returns no usable signal. Wi…
The booster temperature sensor reading is implausible relative to commanded assist or coolant temperature. The…
The booster temperature signal is below the lower diagnostic threshold. Typical causes are a shorted sensor el…
