P2B19Cylinder 5 Injection Pulse Offset Exceeded Learning 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
- P2B19 flags injector 5: its learned zero-fuel offset exceeds the calibrated limit. Ford's diesel OBD summary groups the code with the other odd numbers from P2B11 to P2B1F under the Zero Fuel Calibration monitor, which it files under fuel system feedback control. One distinct trigger is altitude: special service message 53340 covers 2020–2025 F-Super Duty 6.7 L trucks that store these codes when driven above 762 m (2,500 ft). The first step is the service function that clears the minimum fuel mass adaptions of all cylinders with Ford's FDRS tool; Ford told dealers a permanent fix was planned for the second quarter of 2025. CARB counts a fuel feedback loop that has used up its authority as a fault under (f)(4.2.4)(A)(iii).

- PossibleInjector 5 with changed opening behaviour
- PossiblePCM software without the later calibration fix
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
