P02F8Cylinder 11 Injector Circuit Range/Performance
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- Needs a drive cycle to confirm a fix
- How the car detects it
- P02F8 reports an electrically implausible response of the cylinder 11 injector – not an open or short circuit (those are P0211, P0291 and P0292), but a current or voltage pattern outside the expected range. Cylinder 11 exists only on engines with twelve or more cylinders; GM and Ford documents stop at cylinder 8, so the description follows CARB and the documented checks for cylinders 1–8 (current fall time, voltage feedback, regulator at its limit). The injector may be shut off, causing misfire.
- What you may notice
- Check engine light on
- Rough running, misfire on cylinder 11
- Loss of power, smoke (diesel)
- Likely causes
- LikelyInjector electrically aged (piezo capacitance, coil resistance)
- PossibleContact resistance in the injector 11 connector or wiring
- PossibleInjector mechanically sticking (valve lift)
- RareInjector driver stage in the engine module
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
- Repair
