Cylinder Injection Pulse Offset Learning

Diagnostic & Technical Explanation
Code P2B10 (Cylinder 1 Injection Pulse Offset Not Learned) sets when the ECM's per-cylinder injection pulse-offset adaptation (which compensates for small manufacturing differences between injectors) has not yet learned a value, or has learned a value that exceeded its allowed correction limit for the named cylinder. An offset that cannot be learned points at an injector or wiring fault preventing the adaptation routine from running; an offset that hits its limit points at an injector whose actual flow has drifted too far for the compensation range to cover.

These 16 diagnostic trouble codes share one detection mechanism and one repair path, which is why MechanicDB groups them into a single authored fault family rather than repeating the same explanation 16 times.
