Fuel Pressure Relief Control Circuit High

27 brands affected · Generic SAE J2012 description.

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

Safety: This code relates to fuel pressure or a fuel leak, which carries a stall or fire risk.

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?

Serious · drive with care

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.
