P2B1DCylinder 7 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
- P2B1D reports that the correction learned for injector 7 during Ford's zero-fuel calibration has gone beyond its limit; cylinder 7 exists only on the 6.7 L V8. Ford's TSB 25-2412 for 2023–2025 F-Super Duty trucks calls the warning lamp in many such cases incorrect: learned values skewed by operation above 762 m, sometimes with a slightly uneven idle. The repair is a calibration update for PCM and TCM, followed by resetting the minimum fuel mass adaptions. Ford's 2023 summary also shows the neighbouring fuel balancing control, which reports P0281 for cylinder 7 once more than 90 % of its permitted correction is used; both learns act on the same injector, so a balance code next to P2B1D points more towards real injector wear than towards a software issue.
- What you may notice
- Check engine light, sometimes without a real fault
- Slightly uneven idle
- Likely causes
- LikelyCalibration learning wrong values at altitude (Ford TSB 25-2412)
- PossibleInjector 7 worn, often with balance code P0281 as well
- RareInterference on the crank or cam speed signal
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
