What does code P22E2 mean?

Q: What does code P22E2 mean?

Cylinder 3 Alternative Fuel Injector Control Circuit Low. P22E2 indicates that the powertrain control module (PCM) has detected a low-voltage condition on the control circuit for the alternative fuel injector serving cylinder 3. The PCM commands the injector to open, but the circuit feedback suggests the current flow is lower than expected, which can prevent proper fuel delivery on the alternative fuel system.
