P22F2Cylinder 7 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
- Low voltage on the control line of the cylinder 7 gas injector. The code appears in Ford's 2014 code list with MIL and in the installer table of the Altech-Eco/TransEco CNG kits, which on Ford's V8 (F-150 5.0) and V10 (Super Duty 6.8) engines use the PCM to drive gas valves for all cylinders; cylinders 9 and 10 of the V10 get manufacturer codes there. That table lumps a short to ground and an open line into this code, so P22F1 is not used, and shows MIL on for bi-fuel and off for dedicated CNG. A grounded line can hold the valve open and flood cylinder 7 with gas, an open line starves it. In both cases gas operation is disturbed, while a bi-fuel truck can still run on gasoline.
