Just wanted to know if guys think it's a sensor problem or is my computer bad. Oh and when I am driving slow about 25mph or less for a minute the service engine light comes and and my fan starts working until the light goes away. I would appreciate some feed back.

 

The airbag light isn't controlled by the computer. I would check your fuses first.

 

If you have a laptop and an ALDL cable, you may want to try Freescan to get the trouble codes. Also a lot of parts stores (Autozones and OReilly's) can do a diagnostic pin out to find out what is going on.

 

The fans normally come on with the SES, so that is why the fans come on. Find out what is causing the code. Since it comes and goes and at that speed, I would just about bet EGR related.

As far as your ABS and air bag lamps, that can be caused by low system voltage. Check your volt gauge and see what it is telling you.
