P22EECylinder 6 Alternative Fuel Injector Control Circuit Low
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- On engines that burn natural gas or propane through their own gas injectors, the control module watches the drive line of each gas valve. This code means the line to the cylinder 6 gas injector sits at a lower voltage than the switching state allows. The installer table of the Altech-Eco (formerly TransEco) CNG system for Ford F-150, Super Duty and Transit treats both a short to ground and a broken wire as this fault; it lights the MIL on bi-fuel trucks but not on dedicated CNG ones. Ford lists the code with MIL in its 2014 spark-ignition code list and checks it continuously. With a grounded line the valve may stay energised; an open line leaves it shut. Bi-fuel engines usually keep running on gasoline.
- What you may notice
- Check engine light on (bi-fuel versions)
- Rough running or misfire on cylinder 6 in gas mode
- System switches to gasoline or will not enter gas mode
- Likely causes
- LikelyControl wire of the cylinder 6 gas injector chafed through to ground
- PossibleBroken wire or loose plug at the gas injector (counted as Low by this system)
- PossibleGas injector coil burnt open
- RareFaulty output stage in the PCM or gas control module
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
