Tech Notes for P0394 Dodge

In the event of a failure in either the Crankshaft Position (CKP) Sensor or Camshaft Position (CMP) Sensor, the engine can still start. The Powertrain Control Module (PCM) is capable of determining the engine position and initiating startup based on one of these two inputs. However, there may be a small delay in starting as the PCM needs time to establish synchronization. If either the CKP or CMP Sensor signals are absent during engine cranking, a Diagnostic Trouble Code (DTC) is recorded, and the Malfunction Indicator Lamp (MIL) lights up.
