What does code P1222 mean?

Q: What does code P1222 mean?

Injector Control Circuit Intermittent. P1222 on Chrysler vehicles means the powertrain control module (PCM) has detected an intermittent fault in the electrical circuit that operates one or more fuel injectors. The PCM monitors injector control circuits for expected voltage changes when the injector is commanded on and off, and it sets this code when the signal momentarily deviates from the expected pattern without failing completely.
