Co oznacza ten kod błędu?

The code is set when the engine control module (ECM) finds an electrical fault in the internal circuit that controls the fuel flow and fuel pressure control valves. Here the fault is a short circuit to ground in that circuit.

Możliwe przyczyny

Open circuit or short circuit to supply voltage
Open circuit or short circuit on the ground wire
Fuel pressure control valve is damaged
Fuel flow control valve is damaged
The code may be caused by a damaged fuse
The engine control module (ECM) itself is faulty

Co możesz zrobić

1Check that the fuses are intact, since a damaged fuse can cause this code
2Clear the code and road test to see whether it returns
3Check the connectors to the fuel pressure control valve and the fuel flow control valve for contact resistance and oxidation
4Look at the wires to the valves for breaks and chafing
5If you find no fault: have a workshop check the valves, the circuit and the engine control module

Objawy, które możesz zauważyć4

Unusual noise while driving, either occasionally or all the time
Uneven idle
The engine stalls at idle, either occasionally or all the time
