12 manufacturer-specific interpretations across 11 manufacturers in the TuningBot DTC database.
Alfa RomeoThe control module detected improper operation of the Fuel pump relay or circuit. This is the manufacturer-specific definition used by Alfa Romeo.
ChevroletThe control module detected a fault associated with the Injector Circuit Cylinder 8 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 8 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.
DodgeThe control module detected an open circuit or short circuit condition in the Open Or Shorted Condition circuit. This is the manufacturer-specific definition used by Dodge.
FordThe control module registered the fault condition described as "Second Fuel Pump Faulty or Ground Fault". This is the manufacturer-specific definition used by Ford.
HondaThe control module detected a fault associated with the Throttle Position Insufficient circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Honda.
JaguarThe control module detected a fault associated with the Analog Ground circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Jaguar.
JeepThe control module detected an open circuit or short circuit condition in the Open Or Shorted Condition circuit. This is the manufacturer-specific definition used by Jeep.
MitsubishiThe control module registered the fault condition described as "Engine control module (ECM) - processor fault". This is the manufacturer-specific definition used by Mitsubishi.
ECM
NissanThe control module detected improper operation of the Supercharger (SC) bypass valve circuit. This is the manufacturer-specific definition used by Nissan.
VAGThe control module detected an interruption (open circuit) in the Injector 7 circuit, so the expected electrical continuity was not present. This is the manufacturer-specific definition used by Audi.
