Service engine soon light on?
My service engine soon light is on. AGAIN. I had taken it to the Nissan dealership and they didn’t find anything wrong. They reset it and it left but it came back on a few days after getting my tires changed.
Get the car's OBDII port scanned for any codes.
The codes, if any may help to tell what the problem is.
Stores like AutoZone in the USA will do this for free.
