The 2022 Nissan NV's check engine light with vibration typically indicates engine misfires. Code P0302 specifically points to cylinder 2 misfiring, requiring targeted diagnosis.
Nissan NV Engine Options
The NV cargo van offers 4.0L V6 and 5.6L V8 options. Both are proven Nissan engines but can develop misfire issues from common causes.
Causes of Engine Misfires
Ignition System Issues
Spark plugs, ignition coils, and wiring degrade over time. The NV's commercial use with frequent start-stop cycles accelerates ignition component wear.
Fuel Delivery Problems
Clogged fuel injectors, low fuel pressure, or contaminated fuel causes inconsistent fuel delivery to affected cylinders.
Vacuum Leaks
Intake manifold gaskets and vacuum hoses can develop leaks, causing lean misfires often on cylinders nearest the leak.
Compression Issues
Low compression from worn valves or rings causes weak combustion. This is less common but more serious.
Vibration Correlation
Engine vibration from misfires is felt throughout the vehicle, especially at idle. The severity correlates with misfire frequency.
