P22F4Cylinder 7 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
- Plausibility code for the cylinder 7 gas injector circuit: wiring passes the open/short checks, yet the electrical response of the valve does not match what the driver expects. No manufacturer documents this code publicly. For this cylinder, Ford's 2014 overview and the TransEco installer sheet for Ford V8/V10 engines contain just Low (P22F2) and High (P22F3) for this cylinder. The basis is CARB, which requires output components to be checked for correct functional response where feasible. Possible triggers would be a slow or sticking valve, often from compressor oil carried in natural gas, or a coil whose resistance has drifted. Expect intermittent stumbling on gas and possibly a misfire code for cylinder 7.
