What P22EB means
P22EB reports that the cylinder 5 gas injector control circuit is too high, which TransEco Energy's AFCM list attributes to a short to power with the MIL on for bi-fuel use; Ford's 2014 code list likewise carries P22EB for the MIL. The injector stays closed, so cylinder 5 burns no gas and misfires lean, usually logged together with P0305. Gas injectors pull more current than gasoline injectors: Ford's 2003 bi-fuel CNG documentation notes that their drivers had to be stronger because of the extra heat, which also means a shorted coil quickly overloads the output. Measure the coil resistance and look for chafing against a live feed. P22EA is the low side; the gasoline injector of cylinder 5 reports P0274.
P22EB 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 P22EB
- Malfunction indicator lamp on
- Lean misfire on cylinder 5 in gas mode, often with P0305
- Normal running on gasoline
Common causes of P22EB
- Most likelyCylinder 5 control wire chafed against a supply wire
- PossibleOverheated cylinder 5 gas injector with shorted turns
- Less likelyOverloaded 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 P22EB 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). |
| EB | The exact fault in that area. |
What to do next
- Note P22EB 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 P22EB
What does P22EB mean?
P22EB means "Cylinder 5 Alternative Fuel Injector Control Circuit High". P22EB reports that the cylinder 5 gas injector control circuit is too high, which TransEco Energy's AFCM list attributes to a short to power with the MIL on for bi-fuel use; Ford's 2014 code list likewise carries P22EB for the MIL. It is a generic code, so it means the same on every make.
Is it safe to drive with P22EB?
Drive gently and only to a workshop. With P22EB the car can go into limp mode (reduced power) to protect itself.
Will P22EB fail an emissions test?
Yes, it can. P22EB 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 P22EB to fix?
Difficulty: medium. A typical repair takes 0.5 to 3 hours of work. This is a job for a workshop.
Will P22EB clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
