When your 2022 Nissan Titan displays the P0305 code, the engine control module has detected repeated misfires in cylinder 5. The 2022 Titan uses the 5.6L Endurance V8 producing 400 horsepower. With eight cylinders, P0305 is a legitimate diagnostic code.
2022 Titan Powertrain
The second-generation Titan uses Nissan's VK56VD 5.6L V8, a direct-injection engine featuring Variable Valve Event and Lift (VVEL) technology. Paired with a 9-speed automatic transmission, this setup provides strong performance for this full-size truck.
Cylinder 5 Location
On Nissan's V8 configuration, cylinder 5 is typically on the driver side bank. The longitudinal engine mounting in the Titan provides reasonable access to both banks, though upper intake components may need removal.
Common Causes
Spark plug wear is common, especially with towing or heavy use. The VK56 can develop carbon buildup on direct-injection intake valves over time. Ignition coil failure at cylinder 5 is possible. Fuel injector issues may cause lean misfires. Check for vacuum leaks around the intake.
Diagnostic Process
Read all codes and freeze frame data. Inspect cylinder 5's spark plug for wear, fouling, or damage. Test the ignition coil. Check for vacuum leaks. On higher-mileage examples, intake valve carbon inspection may be beneficial. Verify fuel injector operation.
