Was bedeutet der Fehlercode?

The engine control module (ECM) watches combustion in each cylinder and adjusts the fuel amount per cylinder to compensate for small variations. For cylinder 1, the code is stored when the adjustment needs more fuel than the highest permitted adjustment. The fault is detected at idle when the engine is warm. The code is general and does not say what type of fault it is.

Mögliche Ursachen

Fault related to the injectors
Deal first with another fault code, if one is stored
Incorrectly programmed injector class
Incorrectly fitted injector
Leaking injector
Uneven or poor compression

Was Sie tun können

1Read the fault codes; if another fault code is stored, deal with it first and then check whether this code returns
2Check the connector to the cylinder 1 injector, that it is firmly seated and free from oxidation
3Have a workshop check that the correct injector class is programmed and that the cylinder 1 injector is seated correctly and not leaking
4Have a workshop with diagnostic equipment measure the compression in cylinder 1

Symptome, die Sie bemerken können1

The engine runs unevenly at idle
