When your 2022 Nissan Pathfinder displays the P0305 code, the engine control module has detected repeated misfires in cylinder 5. The redesigned 2022 Pathfinder continues with a 3.5L V6 engine, which has six cylinders numbered 1-6, making P0305 a legitimate diagnostic code.
2022 Pathfinder Powertrain
The fifth-generation 2022 Pathfinder (complete redesign) uses the 3.5L VQ35DD direct-injection V6 producing 284 horsepower. A significant change for this generation is the switch from CVT to a traditional 9-speed automatic transmission. The V6 engine configuration remains similar to previous generations.
Cylinder 5 Location
On the VQ35 V6, cylinder 5 is positioned on the rear bank (toward the firewall) in the center position. This location can make access challenging due to the transverse engine mounting and surrounding components.
Common Causes
Even on newer vehicles, spark plug issues can occur from manufacturing defects or poor fuel quality. Ignition coil failure is possible. Direct injection carbon buildup on intake valves accumulates over time, though less significant on newer vehicles. Loose electrical connections from assembly or transport can cause intermittent misfires. First-year redesign software may have calibration updates available.
Diagnostic Process
Read all codes and freeze frame data. As a first-year redesign, check for TSBs addressing known issues. Inspect cylinder 5's spark plug and ignition coil. Verify all electrical connections are secure. Test fuel injector operation at cylinder 5.
