What does code P22E6 mean?

Q: What does code P22E6 mean?

Cylinder 4 Alternative Fuel Injector Control Circuit Low. P22E6 indicates that the powertrain control module (PCM) has detected a low-voltage condition on the control circuit for the alternative fuel injector serving cylinder 4. The PCM commands the injector to open, but the circuit voltage stays below the expected threshold, which can prevent the injector from firing and cause a misfire or rough running on alternative fuel.
