A P0302 code on your 2023 Dodge Challenger signals that cylinder 2 is misfiring beyond acceptable parameters. As one of the final production years for the gas-powered Challenger, maintaining this future collectible in top condition is important.
2023 Challenger: End of an Era
The 2023 Challenger represents the culmination of Dodge's legendary muscle car lineage. Engine options include the 3.6L Pentastar V6, 5.7L and 6.4L HEMI V8s, and various supercharged Hellcat configurations including the mighty Demon 170.
MDS and Misfire Correlation
The 5.7L and 6.4L HEMI engines use Multi-Displacement System cylinder deactivation. When MDS activates, cylinder 2 may deactivate. Faulty MDS lifters or solenoids can cause misfires specifically tied to deactivation cycles.
Supercharged Engine Considerations
Hellcat and Demon engines produce extraordinary power through supercharging. The increased cylinder pressures demand robust ignition. Spark plugs and coils must deliver consistently under extreme conditions. Any weakness causes misfires under boost.
Collector Vehicle Maintenance
Given the 2023 Challenger's potential as a collectible, proper documentation of all repairs is valuable. Use quality OEM or equivalent parts to maintain the vehicle's integrity and value.
Diagnostic Protocol
Identify your specific engine variant before beginning diagnosis. Each engine has different specifications and potential failure points. MDS-equipped HEMI engines warrant additional focus on the cylinder deactivation system.
