Q: What does code P22E5 mean?

Cylinder 4 Alternative Fuel Injector Control Circuit/Open. P22E5 is a generic powertrain code indicating that the engine control module has detected an open circuit or excessive resistance in the control circuit for the alternative fuel injector on cylinder 4. The computer monitors the injector driver circuit and sets this code when the expected current flow is absent, which prevents that injector from delivering alternative fuel to the cylinder.
