P22E0Cylinder 2 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
- P22E0 covers a cylinder 2 gas injector circuit that passes the plain open and short checks yet responds outside its expected window. California's OBD regulation asks for output components to be checked not only for circuit faults but also for a proper functional response; for alternate-fueled vehicles from 2004 to 2018 the gasoline rules applied unchanged, and from 2019 the maker submits its own monitoring plan. The Ford patent US 8,161,946 gives an example of such a functional check for an injector fed by an extra driver. No maker publishes P22E0 itself. Typical triggers are a sluggish or partly stuck injector, a coil past its specification or a driver that cannot deliver the needed current. Cylinder 2 then runs unevenly on gas.
- What you may notice
- Malfunction indicator lamp on
- Uneven idle on gas, cylinder 2 misfire counts
- Fuel trim drifts in gas mode
- Likely causes
- LikelyCylinder 2 gas injector opening or closing too slowly
- PossibleCoil resistance of the injector out of tolerance
- RareDriver stage or supply unable to provide the required current
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
