What P22EA means
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.
P22EA at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyMedium
- Typical labor0.5 to 3 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P22EA
- Malfunction indicator lamp on
- Cylinder 5 runs rich or misfires in gas mode
- Fouled spark plug on cylinder 5
Common causes of P22EA
- Most likelyCylinder 5 control wire shorted to ground along the gas rail
- PossibleInterrupted wire or terminal, flagged as Low by some modules
- Less likelyShorted output stage in the gas control module
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P22EA means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 2 | Area: fuel and air metering (injector circuit). |
| EA | The exact fault in that area. |
What to do next
- Note P22EA and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P22EA
What does P22EA mean?
P22EA means "Cylinder 5 Alternative Fuel Injector Control Circuit Low". P22EA stands for a low voltage on the cylinder 5 gas injector control wire, a code limited to engines with at least five cylinders. It is a generic code, so it means the same on every make.
Is it safe to drive with P22EA?
Drive gently and only to a workshop. With P22EA the car can go into limp mode (reduced power) to protect itself.
Will P22EA fail an emissions test?
Yes, it can. P22EA is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P22EA to fix?
Difficulty: medium. A typical repair takes 0.5 to 3 hours of work. This is a job for a workshop.
Will P22EA clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
