SeriousSeverity: Serious - have it checked soon
Fuel Rail/System Pressure - Too High
Key terms: Catalytic converter: cleans the exhaust gases · 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 fuel pressure in the fuel rail is higher than the engine computer allows, which can flood the engine and stress the fuel system.
2Common causes
- Faulty fuel pressure regulator
- Blocked or crimped fuel return line
- Faulty fuel pressure sensor
- Failing high-pressure fuel pump
- Control module fault
3Can I drive?
Have it diagnosed before driving further. Excessive fuel pressure can flood the engine, dilute the oil and damage the fuel system and catalytic converter.
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.
