What does code P22F2 mean?

Q: What does code P22F2 mean?

Cylinder 7 Alternative Fuel Injector Control Circuit Low. P22F2 indicates that the powertrain control module (PCM) has detected a low-voltage condition on the control circuit for the alternative fuel injector serving cylinder 7. The PCM commands the injector on and off, but the circuit's feedback voltage stays below the expected threshold, which points to a short to ground, excessive resistance, or a failed injector coil.
