Dodge check engine codes
Overview
Dodge shares engines with Chrysler, Jeep, and Ram. EVAP codes, thermostat codes, and Hemi misfires are common topics.
Codes notably common on Dodge
- P0456 Evaporative Emission System Very Small Leak Detected · Dodge notes
- P0455 Evaporative Emission System Large Leak Detected
- P0300 Random or Multiple Cylinder Misfire Detected · Dodge notes
- P0128 Coolant Thermostat (Coolant Temperature Below Regulating Temperature)
- P0420 Catalyst System Efficiency Below Threshold (Bank 1)
Dodge specific notes
- 5.7 liter Hemi engines are frequently reported by owners and repair shops to suffer lifter and camshaft wear that causes ticking and misfires. We have not found a manufacturer bulletin confirming a defect, so treat this as a commonly reported pattern rather than a documented fault.
- Chrysler guidance for EVAP codes calls for a smoke test and software check before replacing the ESIM or canister.
- The 3.6 Pentastar V6 has a documented FCA service guidance for oil filter housing leaks.
