What does this fault code mean?

The ECM keeps an eye on the signal running to the PEM, the fuel pump control module. The code is stored when that signal is too low. It can be caused by an open or short circuit in the wiring, or by 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.

Possible causes

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

What you can do

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 low-pressure pump has no open circuit or short to ground
5Have a workshop with diagnostic equipment check the fuel pump in the tank and its control module

Symptoms you may notice5

The engine does not start but cranks
The engine is hard to start and cranks slowly
The car hesitates or surges during acceleration
The engine stalls, at idle or while driving, at any time or all the time

General guidance for car owners. Diagnosis on the car can point to a different cause.
