It requires a engine scanner to do this. But it came on for a reason and it will do no good to turn it off if you did't fix the problem to start with. It will just come back on.
check with your local Nissan dealer,,on the 1999 they were recalled,,I had a 1999 frontier,and they repalced it for nothing,,,
I think it means you need to check your engine.
No, but it could cause the check engine light to illuminate.
Yes, may read service engine soon, check engine, .....
Engine thermostat malfunction
You should check the battery,transmission, and maybe the engine
Check your engine. Check your fluid levels and add if needed.
you need to check your lights to make sure that the light is not going out!!! A flashing CEL typicly means that there is a misfire.
check the battery with voltmeter without the engine running then check with it running if voltage is higher it is working
