TuningBot DTC Database · v4.37.15
7 manufacturer-specific interpretations across 6 manufacturers in the TuningBot DTC database.
Alfa RomeoThe control module detected improper operation of the AC compressor clutch relay circuit. This is the manufacturer-specific definition used by Alfa Romeo.
ChryslerThe control module registered the fault condition described as "A/C Low Side Temperature Sensor Fault". This is the manufacturer-specific definition used by Chrysler.
FordThe control module registered the fault condition described as "Invalid Test Accelerator Pedal Movement". This is the manufacturer-specific definition used by Ford.
MINIThe control module detected an interruption (open circuit) in the Camshaft Position Actuator 'B' Control circuit, so the expected electrical continuity was not present. This is the manufacturer-specific definition used by MINI.
PorscheThe control module detected a fault associated with the Camshaft Adjustment Bank 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 Camshaft position (CMP) actuator 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 Camshaft Timing Adjustment 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 17939. Documented across Volkswagen Group applications (Audi, SEAT and Škoda included).
