What P22E2 means
P22E2 is logged when the control circuit of the cylinder 3 gas injector reads low. In TransEco Energy's AFCM table the cause column says shorted to ground or open, the MIL comes on in bi-fuel systems and the reaction copies that for a gasoline injector fault. Ford's 2014 code list lists P22E2 as a MIL code. Because a grounded control wire can leave the injector energized, cylinder 3 may be flooded with gas; the catalyst then gets unburnt fuel, and prolonged driving in gas mode is a bad idea. With a broken wire the cylinder is simply starved. Typical spots are chafe points against brackets or the intake manifold. P22E3 is the high side and P22E1 the pure open-circuit code; the gasoline injector uses P0267.
P22E2 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 P22E2
- Malfunction indicator lamp on
- Cylinder 3 runs rich or misfires in gas mode
- Smell of unburnt gas at the exhaust
Common causes of P22E2
- Most likelyCylinder 3 control wire rubbed through against a bracket or the manifold
- PossibleBroken wire or terminal in the cylinder 3 injector circuit
- Less likelyShorted driver output 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 P22E2 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). |
| E2 | The exact fault in that area. |
What to do next
- Note P22E2 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 P22E2
What does P22E2 mean?
P22E2 means "Cylinder 3 Alternative Fuel Injector Control Circuit Low". P22E2 is logged when the control circuit of the cylinder 3 gas injector reads low. It is a generic code, so it means the same on every make.
Is it safe to drive with P22E2?
Drive gently and only to a workshop. With P22E2 the car can go into limp mode (reduced power) to protect itself.
Will P22E2 fail an emissions test?
Yes, it can. P22E2 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 P22E2 to fix?
Difficulty: medium. A typical repair takes 0.5 to 3 hours of work. This is a job for a workshop.
Will P22E2 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
