The 2022 Dodge Durango continues with the 3.6-liter Pentastar V6 and available 5.7-liter and 6.4-liter Hemi V8 engines for this versatile three-row SUV. 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 Durango engine options include cylinder 5 as a legitimate position on the driver's side bank. Proper engine identification guides the diagnostic approach.
V6 vs V8 Considerations
The Pentastar V6 offers excellent efficiency without cylinder deactivation complexity. The 5.7L and 6.4L Hemi V8s feature MDS that can complicate diagnosis. Cylinder 5 doesn't deactivate, but MDS lifter issues can affect overall engine performance.
Common Misfire Causes
Typical cylinder 5 misfire causes include worn spark plugs, failing ignition coil, fuel injector malfunction, intake manifold vacuum leaks, or on direct injection engines, carbon buildup affecting intake valve airflow.
SUV Duty Cycle
The Durango serves family transport, towing, and daily driving. Mixed-use duty cycles can stress different components. Towing accelerates ignition wear while city driving can promote carbon buildup on DI engines.
