SeriousSeverity: Serious - have it checked soon
Exhaust Aftertreatment Fuel Pressure Sensor Circuit Range/Performance
Key terms: Control module: a small computer that runs one part of the car · SAE J2012: the standard generic code list · Powertrain: engine, transmission and emissions
1What it means in plain English
The engine or powertrain control system has stored a fault that does not have specific guidance in this database yet.
2Common causes
- Sensor or actuator fault
- Wiring or connector fault
- Vacuum or intake leak
- Fuel or ignition problem
- Control module fault
3Can I drive?
Do not drive if you smell fuel. Have the fuel system checked before driving further: a fuel leak or loss of pressure can cause a fire or make the engine stall.
This page gives general information. It is not professional advice. For a definite diagnosis and a repair quote, ask a qualified mechanic to inspect the car.
