P0305 Code: 2022 Ram 1500 – What It Means & Cost to Fix

2022 Ram 1500 P0305: Cylinder 5 Misfire Troubleshooting Guide

The 2022 Ram 1500 offers the 3.6-liter Pentastar V6 with eTorque and the 5.7-liter Hemi V8 with eTorque or standard configuration. A P0305 diagnostic trouble code indicates that cylinder 5 of either engine configuration is experiencing misfire events detected by the crankshaft position sensor.

P0305 Code Analysis for Ram 1500 Engines

P0305 translates to "Cylinder 5 Misfire Detected" in OBD-II terminology. Both the V6 and V8 engines in the 2022 Ram 1500 include cylinder 5 as a legitimate cylinder position. Proper identification of your engine type is essential for correct cylinder location during diagnosis.

Root Causes of Cylinder 5 Misfire

Common causes for cylinder 5 misfires on your 2022 Ram 1500 include degraded spark plugs, failing ignition coil, fuel injector malfunction, vacuum leaks at intake manifold or gaskets, carbon buildup on direct injection engines, or on Hemi engines, potential MDS lifter issues affecting adjacent cylinders.

Multi-Displacement System Considerations

The 5.7L Hemi's MDS deactivates cylinders 1, 4, 6, and 7 during light-load cruising. While cylinder 5 remains active, issues with MDS solenoids or lifters can affect engine balance and potentially cause misfires. Listen for ticking noises indicating lifter problems.

Diagnostic Process

Effective diagnosis requires analyzing misfire counter data, performing cylinder-specific component tests, and evaluating mechanical integrity. Stellantis wiTECH diagnostic equipment provides comprehensive access to engine management parameters.
