P2C5ACylinder 5 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
- P2C5A can only occur on engines with at least five cylinders and indicates that cylinder 5's injector B has had its learned offset pulled down to the lower bound. The control has removed as much opening time as it may, yet the cylinder still gets more fuel than intended from this valve. On V engines with Ford numbering cylinder 5 opens bank 2; GM numbering puts it on bank 1. Candidates are a dripping valve, a part with too high a flow rating after a repair, or fuel pressure that the model underestimates. No manufacturer documents P2C5A publicly, and Volvo's bulletin for this code family covers only cylinders 1 to 4. CARB's rule 1968.2 (e)(6.2.2) calls for detection once an adaptive correction has used up its range.

- Likely causes
- LikelyInjector B of cylinder 5 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.
