Q: What does code P22F3 mean?

Cylinder 7 Alternative Fuel Injector Control Circuit High. P22F3 indicates that the powertrain control module (PCM) has detected an abnormally high voltage on the control circuit for the alternative fuel injector serving cylinder 7. This typically means the circuit is shorted to voltage or the injector's internal coil is open, preventing the PCM from properly commanding fuel delivery when the engine runs on the alternative fuel.
