When your 2024 Nissan Frontier displays the P0305 code, the engine control module has detected repeated misfires in cylinder 5. The 2024 Frontier continues with the 3.8L V6 engine producing 310 horsepower. With six cylinders, P0305 is a legitimate diagnostic code.
2024 Frontier Powertrain
The 2024 Frontier uses the proven 3.8L VQ38DD direct-injection V6 paired with a 9-speed automatic transmission. This engine has been refined since its 2020 introduction and provides strong performance for this mid-size truck. No four-cylinder option exists.
Cylinder 5 Location
On the 3.8L V6, cylinder 5 is positioned on the rear bank toward the firewall. The longitudinal engine mounting places this cylinder in a location that may require component removal for access.
Common Causes
On a newer 2024 model, common causes include manufacturing defects in ignition components, loose electrical connections from assembly, or software calibration issues. Spark plug wear is unlikely unless the vehicle has very high mileage. Ignition coil failure is possible. Check for applicable TSBs.
Diagnostic Process
Read all codes and freeze frame data. Check for Nissan TSBs. Verify all ignition system connections. Inspect cylinder 5's spark plug and ignition coil. Test fuel injector operation. A 2024 model should be under warranty coverage for component failures.
