Was bedeutet der Fehlercode?

The ECM monitors the control signal that goes to the fuel pump control module (PEM). This code concerns fuel pump B and is set when there is a fault in that control signal, which can come from wiring, the supply feed or the control module itself.

Mögliche Ursachen

A fault that the CEM has logged itself
Signal wire shorted to ground
Open circuit in the signal wire
Break in the voltage feed between the CEM and the fuel pump control module
Damaged fuel pump control module

Was Sie tun können

1Read the codes in the CEM, since a fault registered there can cause this code
2Check that the fuse for the fuel pump and the supply to the control module are intact
3Use a multimeter to check that the control signal wire is not shorted to ground
4Check the wiring and connectors between the CEM and the fuel pump control module for chafing and breaks
5If nothing is found, have a workshop with diagnostic equipment check the fuel pump control module

Symptome, die Sie bemerken können2

Engine cranks but does not start
Engine stalls while driving, at unpredictable times or all the time
