The P0302 code on your 2022 Dodge Charger signals that the engine control module has detected misfires in cylinder 2 exceeding acceptable parameters. Understanding your specific engine helps ensure accurate diagnosis.
2022 Charger Powertrain Range
The 2022 Dodge Charger continued offering the 3.6L Pentastar V6, 5.7L HEMI V8, 6.4L HEMI V8, and supercharged 6.2L Hellcat engines. Each has different characteristics affecting P0302 diagnosis and repair approaches.
MDS System on HEMI Engines
The 5.7L and 6.4L HEMI V8 engines feature Multi-Displacement System (MDS) cylinder deactivation. This system can shut down cylinder 2 and others during light-load driving. Problems with MDS components can cause cylinder-specific misfires.
High-Performance Engine Considerations
Hellcat engines produce extreme power and generate significant heat. Spark plugs work harder in this application and may require more frequent replacement. Ensure the correct heat range plugs are installed for your driving style.
V6 Pentastar Focus
The 3.6L V6 is the base engine but remains capable. Known issues include occasional ignition coil failures and carbon buildup on intake valves. The direct injection design can contribute to valve deposits over time.
Diagnostic Priorities
Start with ignition system testing—spark plugs and coils cover many misfire causes. Progress to fuel system analysis if ignition components test satisfactory. HEMI owners should consider MDS system evaluation.
