Fix the fault code items and then use a code reader to reset the CPU to put the light out.

SOURCE: service engine soon light

The light comes on when the car's computer detects that something has an incorrect reading that is sending that incorrect reading from the sensing unit to the computer.

Here's how i would attempt to solve it. To reset an service engine soon light take the positive terminal off of the battery and let it drain all the voltage and currents in your vehicle. Like try turning on your radio and turning your car over while the positive terminal is taken off of the battery terminal.

I would say let it sit for atleast 15 minutes then put it back on and start the car back up. If the light still comes back one then you have a small problem that could be many different little things

Check to see that your gas cap isn't worn out and still keeping a seal so when you take it off you should hear air escaping from it

Could be a filter in your fuel tank.

Could be o2 sensors

The list could go on, but to make sure before you start spending a huge amounts of money go to a shop and get them to plug in a scanner into your car to see what exactly the code is.

Good luck bud!

SOURCE: I have 2004 nissan titan

actually could be many reasons, dont want to scare you but there are several sensors that control this grey area, Oxygen,temp,crank,mas,knock sensors. dirty air cleaner, dirty oil (oil sensor) the light will only stay lit if the computer has stored a code, so i suggest getting a scan done to narrow the possibility of causes. What sucks about this is it cost $80-100.00 for a complete engine diagnostic, (fuel pres,timing,air fuel,cat,misfires,etc..) But first,if you take the car to a auto-zone or O'reillys,maybe a napa they will perform a basic code test and hopefully give you a basic or solution to the problem. does the car still run okay? if so have them clear the code,maybe you got some bad gas or something that triggered this. Unless the car is running unusual, or you can hear, feel a problem don't be to alarmed of that light starring at you. Check all fluids,clear code which will shut light off and try again. Hows the fuel mpg holding up.
