P22EBCylinder 5 Alternative Fuel Injector Control Circuit High

  • Generic OBD-II code · Powertrain
  • Turns on the check-engine light
  • Matters for the ITP
  • Can trigger limp mode
How the car detects it
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.
What you may notice
  • Malfunction indicator lamp on
  • Lean misfire on cylinder 5 in gas mode, often with P0305
  • Normal running on gasoline
Likely causes
  • LikelyCylinder 5 control wire chafed against a supply wire
  • PossibleOverheated cylinder 5 gas injector with shorted turns
  • RareOverloaded driver output in the gas control module
Inspection (ITP)
Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
