TuningBot DTC Database · v4.37.15
5 manufacturer-specific interpretations across 4 manufacturers in the TuningBot DTC database.
FordThe control module detected that the signal in the Glow Plug circuit stayed below the expected operating range. This is the manufacturer-specific definition used by Ford.
HondaThe control module judged the G - sensor - performance behaviour implausible for the current operating conditions. This is the manufacturer-specific definition used by Honda.
SuzukiThe control module detected a fault associated with the G Sensor Rough Road Rationality circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Suzuki.
VAGThe control module detected a short circuit to ground in the Camshaft position (CMP) sensor 2/ Bank 2 circuit. This is the manufacturer-specific definition used by Audi.
The control module detected a short circuit to ground in the Camshaft Position Sensor Bank 2 (G163) circuit. This is the manufacturer-specific definition used by Volkswagen.
