TuningBot DTC Database · v4.37.14
7 manufacturer-specific interpretations across 7 manufacturers in the TuningBot DTC database.
ChevroletThe control module detected a fault associated with the A/C Refrigerant Condition Very 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 Chevrolet.
ChryslerThe control module detected a fault associated with the A/C Refrigerant Condition Very 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 Chrysler.
MINIThe control module detected a fault associated with the Pedal Position Sensor circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by MINI.
MitsubishiThe control module detected that the Radiator outlet engine temperature (ECT) signal stayed above the expected range. This is the manufacturer-specific definition used by Mitsubishi.
PSAThe control module detected that the Gear selection actuator electric motor control fault was not coherent with related operating data. Documented for the Automated manual gearbox electric control ECU on Peugeot applications; the same PSA control units are also fitted to Citroën models.
RenaultThe control module detected a fault associated with the Temp Sensor Upstream particulate filter circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Renault.
VAGThe control module detected that the Throttle motor position sensor 1 signal stayed above the expected range. This is the manufacturer-specific definition used by Audi.

Diagnostic Trouble Code (7 interpretations). The control module detected a fault associated with the A/C Refrigerant Condition Very 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 Chevrolet.

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.
