P22EACylinder 5 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
- P22EA stands for a low voltage on the cylinder 5 gas injector control wire, a code limited to engines with at least five cylinders. TransEco Energy's AFCM table points to a grounded wire or an open line, lights the MIL in bi-fuel use and applies the gasoline injector fault response; Ford's 2014 code list, written for V8 engines among others, keeps P22EA as a MIL code. A control wire resting on ground can energize the injector without pause, so cylinder 5 may run far too rich and its spark plug may foul; with an open line it misses gas instead. Inspect the wire along the rail of the affected bank first. P22EB is the high side, P22E9 the plain open circuit, and the gasoline injector reports P0273.
