P22E3Cylinder 3 Alternative Fuel Injector Control Circuit High
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P22E3 tells that the cylinder 3 gas injector circuit is held high. TransEco Energy's AFCM list names a short to power, MIL on for bi-fuel use, and Ford's 2014 code list also ties P22E3 to the MIL. With the line stuck at supply voltage the injector cannot be switched on, so cylinder 3 gets no gas and misfires lean. In GM's bi-fuel Silverado layout the ECM calculates the pulse widths while a separate fuel injector control module passes them to the gas injectors, so the fault can sit in the wiring between that module and the injector, in the injector itself, or in the module output. Gasoline operation remains normal. P22E2 is the low side and P0268 the high-side code of the gasoline injector.
- What you may notice
- Malfunction indicator lamp on
- Lean misfire on cylinder 3 in gas mode, often with P0303
- Noticeable loss of power on gas
- Likely causes
- LikelyCylinder 3 control wire shorted to a 12 V feed
- PossibleShorted turns in the cylinder 3 gas injector
- RareFaulty output of the injector control module
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
