Q: What does code P22DA mean?

Cylinder 1 Alternative Fuel Injector Control Circuit Low. P22DA indicates that the powertrain control module (PCM) has detected a low-voltage condition on the control circuit for the alternative fuel injector serving cylinder 1. This means the PCM's command signal to that injector is being pulled below its expected voltage range, which can prevent the injector from opening and delivering fuel.
