Video Summary

When your check engine light comes on, start by noticing whether it’s steady or flashing. A steady light may mean your Nissan needs an inspection, even if it runs fine. A flashing light can mean a misfire, so follow your Owner’s Manual right away and get it checked promptly. Stop as soon as it’s safe if the light is flashing with severe shaking or major power loss, or if you notice smoke, a strong fuel or burning smell, or an overheating warning. If the light is steady and you just filled up, park safely, turn off the engine and check that the fuel cap is secure, but don’t assume that’s the whole answer. A diagnostic inspection starts by reading the stored trouble codes, which are a starting point, not the full repair answer; more testing may be needed. Bring your VIN and recent service records, a photo of the warning light if you can, and notes on when it came on and anything you noticed while driving.
