6 manufacturer-specific interpretations across 5 manufacturers in the TuningBot DTC database.
ChevroletThe control module detected that the signal in the A/C Request circuit stayed above the expected operating range. This is the manufacturer-specific definition used by Chevrolet.
ChryslerThe control module detected that the signal in the A/C Request circuit stayed above the expected operating range. This is the manufacturer-specific definition used by Chrysler.
FordThe control module determined that the Intake Manifold Runner Control did not change state as commanded and appears stuck. This is the manufacturer-specific definition used by Ford.
MazdaThe control module determined that the Intake manifold air control solenoid, bank 2 - solenoid did not change state as commanded and appears stuck. This is the manufacturer-specific definition used by Mazda.
VAGThe control module detected an interruption (open circuit) in the Fuel shut - off solenoid circuit, so the expected electrical continuity was not present. This is the manufacturer-specific definition used by Audi.
