Was bedeutet der Fehlercode?
The engine control module (ECM) monitors the signal to the injectors. The code for cylinder 2 is set when the signal is faulty, because the signal wire is shorted to supply voltage.
Mögliche Ursachen
- Signal wire shorted to supply voltage
- Damaged injector
Was Sie tun können
- 1Note that the code applies to cylinder 2 and check the wire to that injector in particular
- 2With the engine control module connector disconnected, use a multimeter to check that the signal wire to cylinder 2 has no contact with battery positive
- 3Look for chafing on the wire to cylinder 2, especially where it may have been pinched or rubbed against something
- 4Check the injector for damage and the connector for corrosion
- 5If you find no fault: have a workshop check the injector
Symptome, die Sie bemerken können2
- The engine does not start, or only gives a clicking sound when starting is attempted
- Poor performance and lack of power while driving
Was der Fehler beeinflussen kann1
