Co oznacza ten kod błędu?

The ECM watches the control signal on its way to the PEM, the fuel pump control module. The code is stored when that signal is incorrect. The cause may be an open or short circuit in the wiring, or a fault in the fuel pump in the tank that gives too low pressure. The code is general and does not say what type of fault it is.

Możliwe przyczyny

Open or short circuit in the wiring
Fault in the fuel pump in the tank, giving too low pressure

Co możesz zrobić

1Read and note the fault code, clear it and test drive to see whether it returns
2Check that the fuses are intact
3Check the connector to the fuel pump control module for contact resistance and oxidation
4With the ignition off, use a multimeter to check that the control wire to the pump control module has no open or short circuit
5Have a workshop with diagnostic equipment check the fuel pump in the tank and its control module
