Co oznacza ten kod błędu?
The ECM watches the fuel pressure control valve and how it works. The fault is set when the signal is invalid, for example when the PWM signal is too high or too low, or when the valve draws too much current.
Możliwe przyczyny
- The fuel pressure control valve is sticking, and there may be contamination such as water or dirt in the fuel system
- Signal wire shorted to ground or voltage
- Damaged fuel pressure control valve
Co możesz zrobić
- 1Read the code, clear it and road test to see whether it returns
- 2Think back to whether you recently fuelled with poor-quality fuel, since water and dirt can make the valve stick
- 3Use a multimeter to check that the signal wire is not shorted to ground or positive
- 4Look at the valve connector for oxidation and loose connections
- 5If the fault remains, have a workshop check the fuel system and the fuel pressure control valve with diagnostic equipment
