Service engine soon , nissan sentra 2002


Asked by May 20, 2014 at 09:20 PM about the 2002 Nissan Sentra GXE

Question type: Maintenance & Repair

1 Answer


If it is blinking on and off it's a misfire detected , if it goes from blinking to steady then that also is bad. either of these should take you to the mechanic. If it just came on steady then it's detecting something in the emission system that could be as silly as a looses gas cap.
