Was bedeutet der Fehlercode?

The engine control module (ECM) compares the fuel pressure on the high-pressure side with the largest permitted deviation above the correct pressure, which depends on engine load and speed. The code is set when the deviation becomes too large. A low fuel level in the tank is one of the causes. The check is only made with the engine running.

Mögliche Ursachen

Low fuel level in the tank
The fuel flow control valve is damaged
The fuel pressure control valve is damaged
Air in the fuel system
Too high back pressure on the return side of the fuel system

Was Sie tun können

1Check the fuel level in the tank and top up if it is low.
2Search the fuel system for leaks, for example wet spots or a smell of fuel under the car.
3If there are fault codes for the fuel pump, deal with them before going further.
4With a diagnostic tool, follow fuel pressure in live data at idle and at light throttle; the measured value should track the requested one.
5Have a workshop check the pressure sensor connector and wiring, the injector valves and the fuel filter, as this needs measurements.
