When your 2024 Nissan Titan displays the P0304 code, the engine control module has detected recurring misfires in cylinder 4. The Titan's powerful 5.6L Endurance V8 requires understanding of V8 architecture and full-size truck demands for effective diagnosis and repair of this combustion problem.
Understanding P0304 in the 2024 Titan
The 2024 Titan features the 5.6L Endurance V8 producing 400 horsepower through variable valve timing and direct fuel injection. This V8 positions cylinder 4 on the right (passenger) bank toward the rear of the engine. Nissan's sophisticated engine management identifies the specific misfiring cylinder through crankshaft velocity pattern analysis with high precision.
Full-Size Truck V8 Misfire Causes
The high-output V8 demands quality ignition components capable of reliable performance under varying loads. Spark plug electrode wear occurs through normal operation but accelerates under towing and hauling conditions. Ignition coils must generate robust sparks for consistent combustion. Direct injection technology contributes to intake valve carbon accumulation over time.
Diagnostic Process
Retrieve all codes and analyze freeze frame data—high engine load values suggest towing-related stress. Access cylinder 4 on the right bank of the V8. The full-size truck's engine bay provides reasonable working space. Test ignition coil output and spark plug condition. Verify fuel injector operation. Consider truck duty cycle in your diagnostic approach.
Repair Solutions
Install Nissan-specified spark plugs for the 5.6L V8 at correct torque values. Replace ignition coils showing degraded output. Address fuel system concerns as identified. Trucks used for heavy towing may benefit from proactive maintenance scheduling ahead of standard intervals.
