What does this fault code mean?
The engine control module (ECM) adjusts the fuel amount per cylinder to compensate for variations. For cylinder 2, the learned injection offset has reached its highest permitted level, and the code is stored when the need for adjustment exceeds the limit for how far fuel may be increased. The code is general.
Possible causes
- 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
What you can do
- 1Read the fault codes; if another fault code is stored, deal with it first, then drive and see whether this code returns
- 2Check the connector to the cylinder 2 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 2 injector is seated correctly and not leaking
- 4Have a workshop with diagnostic equipment measure the compression in cylinder 2, since uneven or poor compression may be behind it
Symptoms you may notice1
- A noise from the engine, at any time or all the time
