The 2020 Dodge Charger offers the 3.6-liter Pentastar V6 and various Hemi V8 engines including the 5.7L, 6.4L, and supercharged 6.2L Hellcat. All configurations include cylinder 5 as a legitimate position. A P0305 diagnostic trouble code indicates the engine management system has detected a misfire at this cylinder.
Understanding P0305 on Charger Engines
The P0305 code signifies "Cylinder 5 Misfire Detected." On the Pentastar V6, cylinder 5 is on the driver's side rear. On Hemi V8 engines, cylinder 5 is also driver's side, positioned using Stellantis cylinder numbering convention. Both engine families legitimately contain cylinder 5.
Pentastar V6 Considerations
The 3.6L Pentastar V6 producing 292 horsepower is the base engine. Common cylinder 5 misfire causes include worn spark plugs, failing ignition coil, fuel injector issues, or intake manifold vacuum leaks. Direct injection versions may develop intake valve carbon buildup.
Hemi V8 with MDS
The 5.7L Hemi features Multi-Displacement System (MDS) that deactivates cylinders 1, 4, 6, and 7 during light-load operation. Cylinder 5 doesn't deactivate but MDS lifter issues can affect adjacent cylinders and overall engine balance.
High-Performance Variants
The 6.4L 392 Hemi (no MDS) and supercharged Hellcat are designed for performance. Higher stress levels can accelerate ignition component wear, particularly on vehicles driven aggressively.
