Co oznacza ten kod błędu?

The engine control module keeps watch on the fuel pressure control valve. If the pressure the valve produces does not match the value the module has requested, the code is set. The fault can lie in the connector, in the wiring to the valve or in the valve itself.

Możliwe przyczyny

Poor contact or oxidation at the valve connector
Power supply interrupted
Open circuit in the signal cable
Signal cable shorted to ground or supply voltage
Damaged fuel pressure control valve

Co możesz zrobić

1The fuel system works at very high pressure and can cause injury, so leave it alone
2Check the valve connector for play, contact resistance and oxidation
3Check that the fuel can flow freely from the tank, with no blocked lines, filter or pump
4Use a multimeter to check that the wires to the valve are not broken and have no contact with ground or supply voltage
5If the code returns after clearing and a test drive, and nothing is found, a workshop should replace the fuel pressure control valve
