7 manufacturer-specific interpretations across 6 manufacturers in the TuningBot DTC database.
ChevroletThe control module detected a fault associated with the Injector Circuit Cylinder 7 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 7 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.
JaguarThe control module detected improper operation of the Sensor power supply. This is the manufacturer-specific definition used by Jaguar.
MitsubishiThe control module registered the fault condition described as "Ignition timing error". This is the manufacturer-specific definition used by Mitsubishi.

PorscheThe control module detected a fault associated with the Fuel Injector Cylinder 4 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 4 circuit, so the expected electrical continuity was not present. This is the manufacturer-specific definition used by Audi.
