9 manufacturer-specific interpretations across 8 manufacturers in the TuningBot DTC database.
BMW
1 interpretation
Dodge
1 interpretationThe control module detected an interruption (open circuit) in the Vacuum Reservoir Solenoid circuit, so the expected electrical continuity was not present. This is the manufacturer-specific definition used by Dodge.
Hyundai
1 interpretationThe control module detected improper operation of the Pressure Regulator Solenoid. This is the manufacturer-specific definition used by Hyundai.
Jaguar
1 interpretationThe control module detected a fault associated with the Throttle Valve Spring 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.
Jeep
