Code P0390 Dodge Description

The P0390 diagnostic trouble code (DTC) for Dodge vehicles specifically refers to the Camshaft Position Sensor Circuit Bank 2 Sensor 2. This code indicates that there is an issue with the electrical circuit of the camshaft position sensor located on bank 2, which is typically the side of the engine that does not contain cylinder 1. The camshaft position sensor is responsible for monitoring the position of the camshaft in relation to the crankshaft, allowing the engine control module (ECM) to determine the precise timing of fuel injection and ignition.

Tech Notes for P0390 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.
