When your 2024 Nissan Pathfinder displays the P0305 code, the engine control module has detected repeated misfires in cylinder 5. The 2024 Pathfinder uses the 3.5L V6 engine producing 284 horsepower, which has six cylinders numbered 1-6, making P0305 a legitimate diagnostic code.
2024 Pathfinder Powertrain
The fifth-generation Pathfinder continues with the proven 3.5L VQ35DD direct-injection V6 paired with a 9-speed automatic transmission. This engine configuration has been refined over the generations and provides smooth power delivery for this three-row SUV.
Cylinder 5 Location
On Nissan's VQ35 V6, cylinder 5 is located on the rear bank (toward the firewall) in the center position. The transverse engine mounting makes this cylinder somewhat challenging to access, potentially requiring removal of intake components.
Common Causes
Spark plug wear is a primary cause, though less likely on a 2024 model unless it has high mileage. Ignition coil failure can occur at cylinder 5. Direct injection engines can accumulate carbon on intake valves over time. Fuel injector issues may cause lean misfires. Loose electrical connections from assembly or service work can cause intermittent misfires.
Diagnostic Process
Read all diagnostic codes and freeze frame data. Check for TSBs addressing 2024 Pathfinder issues. Inspect cylinder 5's spark plug and ignition coil. Verify all electrical connections are secure. Test fuel injector operation at cylinder 5.
