SeriousSeverity: Serious - have it checked soon
Fuel Pressure Regulator 1 Control Circuit
Key terms: Oxygen sensor: measures oxygen in the exhaust gas · Mass air flow sensor: measures the air going into the engine · SAE J2012: the standard generic code list · Powertrain: engine, transmission and emissions
1What it means in plain English
This code is in the fuel and air metering range, which includes fuel-pressure and camshaft-timing faults.
2Common causes
- Dirty or faulty mass air flow sensor
- Vacuum or intake air leak
- Weak fuel pump or clogged fuel filter
- Faulty fuel injector
- Faulty oxygen sensor
- Wiring or connector 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.
