P22F0Cylinder 6 Alternative Fuel Injector Control 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
- Unlike the pure wiring faults P22EE/P22EF, this code is meant for a cylinder 6 gas injector circuit that is electrically intact but behaves implausibly, for example a current rise or switching response that does not fit the command. No manufacturer documents this code publicly: neither the Ford 2014 code list nor the Altech-Eco/TransEco CNG table contains it; both stop at Low and High for this cylinder. The basis is therefore the CARB requirement that output components be checked for proper functional response, not only for circuit continuity. If a manufacturer uses it, a sticking or fouled gas valve and resistance drift of the coil would be the likely triggers, with uneven running on gas.
- What you may notice
- Uneven idle or hesitation in gas mode
- Cylinder 6 misfire count rising on gas only
- Check engine light possible
- Likely causes
- PossibleCylinder 6 gas valve sticking from oil or deposits carried in the gas
- PossibleCoil resistance drifted out of the expected window
- RareCorroded plug causing a slow current rise
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
