Was bedeutet der Fehlercode?
Although the code is named signal missing, it applies when the signal to the injector for cylinder 2 is faulty. The engine control module drives the injectors through a high-output stage and monitors the signal wire to each one. The fault concerns cylinder 2 only, but it can be clearly felt while driving.
Mögliche Ursachen
- Poor contact, with loose connections or oxidation at the injector
- Break in the signal wire
- Signal wire shorted to ground or supply voltage
- Damaged injector
Was Sie tun können
- 1Read the fault code, clear it and road test to see whether it returns
- 2Check that the connector to the cylinder 2 injector is fully engaged and free from oxidation
- 3Follow the two wires to the cylinder 2 injector and look for breaks, chafing and shorts to ground
- 4With the connector unplugged, use a multimeter to check that the wires have no connection to ground (the body)
- 5If you have a diagnostic tool, compare the cylinder 2 injector with the others in live data. A clear difference points to it
- 6If the fault remains, have a workshop check the injector output stage and decide whether the injector should be replaced
Symptome, die Sie bemerken können2
- Car drives poorly and lacks power
- Text message and warning symbol in the display
Was der Fehler beeinflussen kann2
- Engine speed may be limited
- The car goes into limp-home mode
