A P0302 code on your 2022 Dodge Durango indicates that the powertrain control module has detected cylinder 2 misfiring beyond acceptable limits. Proper diagnosis maintains this capable SUV's performance and reliability.
2022 Durango Powertrain Configuration
The 2022 Dodge Durango offers the 3.6L Pentastar V6 standard, with available 5.7L HEMI V8 and 6.4L HEMI V8 (SRT/Hellcat) options. Each engine presents different diagnostic considerations for P0302.
MDS on HEMI Engines
The 5.7L HEMI features Multi-Displacement System cylinder deactivation for improved fuel economy. Cylinder 2 is one of the cylinders controlled by MDS. Lifter failures within the MDS system can cause persistent misfires in specific cylinders.
SRT and Hellcat Performance
The high-performance 6.4L HEMI and supercharged Hellcat engines in the Durango don't use MDS. Their misfires typically relate to ignition components stressed by high power output or fuel system issues. Quality components are essential.
V6 Direct Injection Effects
The 3.6L Pentastar's direct injection design can lead to carbon deposits on intake valves over time. These deposits restrict airflow and can cause misfires. Regular maintenance helps minimize buildup.
Family Vehicle Considerations
The Durango serves as a family hauler for many owners. Prompt misfire repair prevents stranded situations and ensures reliable transportation. Don't delay diagnosis when the code appears.
