P22DECylinder 2 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
- P22DE stands for a control line of the cylinder 2 gas injector whose voltage is too low. TransEco Energy's AFCM fault table blames a grounded or interrupted wire and turns on the MIL for bi-fuel vehicles; Ford's 2014 OBD code list includes P22DE as a MIL code too. California's OBD rule counts a bi-fuel car among alternate-fueled vehicles just for the periods it actually burns gas, so this monitor matters mainly in gas mode, and on gasoline the car normally behaves as usual. If the grounded wire keeps the injector energized, cylinder 2 is flooded with gas and the plug may foul; a separated wire starves it instead. P22DF is the high side, P22DD the open-circuit code, and P0264 belongs to the gasoline injector.
- What you may notice
- Malfunction indicator lamp on
- Rich misfire or fouled spark plug on cylinder 2 in gas mode
- Gas operation interrupted, engine runs on gasoline
- Likely causes
- LikelyCylinder 2 injector control wire grounded on engine or body
- PossibleOpen wire or pin, reported as Low by modules like the TransEco AFCM
- RareShorted output transistor in the gas control module
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
