When your 2023 Nissan Murano displays the P0305 code, the engine control module has detected repeated misfires in cylinder 5. The 2023 Murano continues with the 3.5L VQ35DE V6 producing 260 horsepower. With six cylinders, P0305 is a legitimate diagnostic code.
2023 Murano Powertrain
The 2023 Murano maintains the proven 3.5L VQ35DE V6 engine paired with a CVT transmission. This naturally aspirated engine provides smooth power delivery suitable for the Murano's luxury-oriented positioning. All Muranos have this V6 configuration.
Cylinder 5 Location
On the VQ35 V6, cylinder 5 is positioned on the rear bank (toward the firewall) in the center position. Access requires working from above through tight spaces or removing intake components.
Common Causes
On a newer 2023 model, spark plug wear is less likely unless mileage is high. Ignition coil failure can still occur. Manufacturing defects or loose connections are possible causes on newer vehicles. Check for TSBs addressing known issues. Fuel injector problems may cause lean misfires.
Diagnostic Process
Read all codes and freeze frame data. Check for Nissan TSBs for the 2023 Murano. Verify all ignition system connections are secure. Inspect cylinder 5's spark plug and ignition coil. Test fuel injector operation. Check warranty coverage for component failures.
