The error code P0660 on a 2006 Dodge Charger indicates a problem with the intake air heater circuit. This code typically points to an issue with the intake air heater relay, wiring, or the heater element itself. It can affect engine performance, particularly during cold starts, as the intake air heater is designed to help improve engine efficiency by warming the air entering the engine. It's advisable to diagnose the specific issue and address it to prevent further complications.
