The 2022 Dodge Challenger continues the muscle car legacy with the 3.6-liter Pentastar V6 and various Hemi V8 options from 5.7L through supercharged variants. A P0305 diagnostic trouble code indicates that cylinder 5 of any engine configuration is experiencing misfire events detected by the crankshaft position sensor.
P0305 Code Analysis
P0305 translates to "Cylinder 5 Misfire Detected" in OBD-II terminology. All Challenger engines include cylinder 5 as a legitimate driver's side cylinder position. Proper identification of your specific engine determines the diagnostic approach.
Misfire Diagnosis by Engine
The V6 SXT focuses on ignition, fuel, and carbon buildup concerns. The 5.7L R/T adds MDS complexity. The 6.4L Scat Pack eliminates MDS. Supercharged models add boost-related considerations including charge air cooling and spark plug heat range.
Performance Modifications
Many Challenger owners modify their vehicles for additional power. Tunes, intakes, and exhaust modifications can affect fuel trims and ignition requirements. Ensure modifications are properly calibrated to prevent misfires.
Diagnostic Equipment
Stellantis wiTECH or equivalent diagnostic tools provide the most comprehensive data for Challenger engines. Generic scanners can read codes but may miss specific parameters relevant to MDS or supercharged operation.
