Was bedeutet der Fehlercode?

The engine control module drives the fuel injectors through a high-output stage and checks how quickly they discharge. Although the code is named signal missing, it is set when the discharge time is outside the permitted range. Causes can be a blocked fuel return line, loose or corroded connections, an open or shorted signal wire, or a damaged injector.

Mögliche Ursachen

Blocked return line from the injectors
Loose connection, contact resistance or oxidation in the connectors
Open circuit in the signal wire
Signal wire shorted to ground or supply voltage
Damaged injector

Was Sie tun können

1If other fault codes for the injectors are stored, deal with those first
2Read the fault code, clear it and road test to see whether it returns
3Check all injector connectors: are they fully engaged, and free from oxidation?
4Follow the wiring to the injectors and look for breaks, chafing and shorts to ground
5If you have a diagnostic tool, compare the injector values in live data. An injector that clearly differs from the others points to the fault
6If the fault returns, have a workshop check that the fuel return line is not blocked and decide whether an injector needs replacing
