P2C5CCylinder 6 Fuel Injector B Offset Learning At Min Limit
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Needs a drive cycle to confirm a fix
- How the car detects it
- P2C5C reports that the injector B offset for cylinder 6 has been learned down to its minimum. In practice the most telling check is the learned value itself: a scan tool that shows the offsets of all B injectors makes one outlier obvious. For an overdelivering valve a pressure-hold test of the rail after shut-off helps, since a dripping injector lets pressure fall faster and may leave a fuel smell or a long hot start. On in-line sixes cylinder 6 is the last one on the rail; on V6 engines its bank depends on the maker's numbering. No manufacturer documents P2C5C publicly; Volvo's injector B bulletin stops at cylinder 4. Under section (e)(6.2.2) of CARB's 13 CCR 1968.2 the exhausted correction counts as a fault.
- What you may notice
- Check engine light
- Often nothing else noticeable
- Long hot start or rough first seconds, possibly misfire on cylinder 6
- Possibly fuel smell or higher consumption
- Likely causes
- LikelyInjector B of cylinder 6 leaking at the seat and adding fuel after closing
- PossibleReplacement injector of a different flow rating or not matched to the engine software
- PossibleOld learned values not reset after injector or software work
- RareSupply pressure on this injector set higher than the model assumes (regulator)
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
