P262AFuel Injector - Pilot Injection Not Learned
- 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
- Common-rail diesels learn how long each injector must be energised to deliver its tiny pilot shot. Ford's 6.7 L Power Stroke does this with Zero Fuel Calibration: during overrun with rail pressure set to 300 bar, one injector fires small test pulses and the resulting rise in crankshaft speed tells the module the real quantity; the learned offset then corrects every pilot injection of that injector. P262A means the routine kept failing to learn. The 2013 Ford summary sets it after 100 s of valid conditions without a learned value (890-1,610 rpm, gears 4-6, converter locked, coolant at least 50 °C); the 2017 edition counts 30 attempts of 0.8 s or more. P02CC-P02DB cover offsets at their limits. CARB requires faults in pilot-quantity feedback control to be detected.
- What you may notice
- Check engine light
- Louder combustion knock, especially at idle and light load
- Often no noticeable change in driveability
- Likely causes
- LikelyDriving pattern rarely offers long overrun phases in high gear (towing, city use)
- PossibleInjector drift or wear so the test pulse does not give a usable response
- RareDisturbed crankshaft speed or rail pressure signal
- RareNon-original engine calibration interfering with the learning routine
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
- Repair
- Hard · Usually a job for a workshop.Typical cost: €0 – €2,500
