10 manufacturer-specific interpretations across 10 manufacturers in the TuningBot DTC database.
Alfa RomeoThe control module detected improper operation of the Idle speed control (ISC). This is the manufacturer-specific definition used by Alfa Romeo.
ChevroletThe control module detected a fault associated with the Throttle control unit - signal variation circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Chevrolet.
HyundaiThe control module detected a fault associated with the Engine Coolant Temperature Sensor - Low circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Hyundai.
JaguarThe control module detected that the Closed throttle position (CTP) switch signal stayed below the expected range. This is the manufacturer-specific definition used by Jaguar.
Land RoverThe control module determined that the Intake manifold air control system, bank 1 - valve did not change state as commanded and appears stuck. This is the manufacturer-specific definition used by Land Rover.
MazdaThe control module registered the fault condition described as "Intake manifold air control - stuck close". This is the manufacturer-specific definition used by Mazda.
MINIThe control module detected that the DISA Control signal stayed below the expected range. This is the manufacturer-specific definition used by MINI.
SubaruThe control module detected that the Idle air (IAC) control valve, circuit 2 voltage stayed below the expected range. This is the manufacturer-specific definition used by Subaru.
SuzukiThe control module detected improper operation of the Main Throttle Idle Actuator. This is the manufacturer-specific definition used by Suzuki.
VAGThe control module detected a short circuit to battery voltage in the Intake manifold air control solenoid 1 circuit. This is the manufacturer-specific definition used by Audi.

If the fault logic lives in the ECU calibration, yes: our DTC Removal file service disables the specific fault entry and, where the ECU needs it, corrects the checksum too. Not sure whether your case qualifies? Request a free assessment and our engineers will check your ECU file.
