TuningBot DTC Database · v4.37.14
11 manufacturer-specific interpretations across 10 manufacturers in the TuningBot DTC database.
ChevroletThe control module detected a fault associated with the Injector Circuit Cylinder 6 Intermittent 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.
ChryslerThe control module detected a fault associated with the Injector Circuit Cylinder 6 Intermittent circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Chrysler.
FordThe control module registered the fault condition described as "Fuel Pump Secondary Circuit Fault". This is the manufacturer-specific definition used by Ford.
HyundaiThe control module detected that the Active Air Flap F/B voltage stayed above the expected range. This is the manufacturer-specific definition used by Hyundai.
JaguarThe control module detected improper operation of the VSV 2 circuit. This is the manufacturer-specific definition used by Jaguar.
MazdaThe control module detected improper operation of the Fuel pump (FP) - secondary circuit. This is the manufacturer-specific definition used by Mazda.
MitsubishiThe control module detected improper operation of the Accelerator pedal position (APP). This is the manufacturer-specific definition used by Mitsubishi.
PorscheThe control module detected a fault associated with the Fuel Injector Cylinder 1 circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Porsche.
VAGThe control module detected an interruption (open circuit) in the Injector 1 circuit, so the expected electrical continuity was not present. This is the manufacturer-specific definition used by Audi.
The control module detected an interruption (open circuit) in the Fuel Injector for Cylinder 1 (N30) circuit, so the expected electrical continuity was not present. This is the manufacturer-specific definition used by Volkswagen. Volkswagen Group tools also report it as fault code 17645. Documented across Volkswagen Group applications (Audi, SEAT and Škoda included).
VolvoThe control module detected that closed-loop control of the Turbocharger (TC) boost deviated from its target. This is the manufacturer-specific definition used by Volvo.

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.
