What does code P22E7 mean?

Q: What does code P22E7 mean?

Cylinder 4 Alternative Fuel Injector Control Circuit High. P22E7 indicates that the powertrain control module (PCM) has detected an abnormally high voltage on the control circuit for the alternative fuel injector serving cylinder 4. The PCM commands the injector to open by pulling the circuit to ground, so a high-voltage reading means the circuit is open, shorted to power, or the injector coil is not completing the path to ground as expected.
