Code P2618 Dodge Description
The P2618 diagnostic trouble code (DTC) for Dodge vehicles refers to the Crankshaft Position Signal Output Circuit Low. This code indicates that the Engine Control Module (ECM) has detected a low voltage signal from the crankshaft position sensor. The crankshaft position sensor is a vital component in the engine management system, as it provides the ECM with data on the position and speed of the crankshaft. This information is crucial for the ECM to accurately control ignition timing, fuel injection, and other engine functions.
