Dodge Trouble Codes and Known Issues

Dodge and Ram (Stellantis) share engines and electronics with Jeep and Chrysler: the 3.6 Pentastar V6, the Hemi V8s and, in smaller models, four-cylinder engines. The EVAP system uses its own leak detection unit, and the automatic transmissions are diagnosed by reading their own module.

Most searched models: Ram 1500, Ram 2500, Durango, Journey, Charger, Challenger, Grand Caravan, Neon and Caliber.

Common problems on Dodge vehicles

• EVAP leak detection unit (NVLD or ESIM).
• Oil filter housing and oil pressure sensor on the Pentastar.
• Crankshaft and camshaft sensors on the Neon and Caliber.
• Cylinder deactivation (MDS) on the Hemi, with misfires and lifter noise.

Tips for diagnosing a Dodge

• Ram and Dodge vehicles store many manufacturer codes (P1xxx, and P3xxx on the Hemi); use a scan tool that shows their description.
• On the Hemi, use oil of the specified viscosity: the MDS system depends on it.
