the check engine light is emission related,has nothing to do with oil the oil gauge problem is a bad ground or sending unitService engein light and oil tempeture?
marfanman00 is right on. Anytime you get a check engine light it is related to your emissions. This is basically the smog. Some of the questions that will rise are is it burning clean, maybe a sensor is off, check to see if you pass smog or not etc. Getting that check engine light (CEL) code will help out a lot. So if Autozone can read it for you or if you have to take it in to the shop. Either way it will help you a lot. You'll be surprised some small shops if you dive by and negotiate a small affordable deal of your satisfaction and an agreement from them maybe, just maybe they'll read that code for you for half the price. Good Luck!
check the oil sending unit...it could be shorting out and cause the gauges to read wrong
Make and model might help. Are you sure its oil temp and not pressure? This site may be able to help you find out codes the old way.http://www.auto-diagnostic-codes.com/Pet鈥?/a> Just enter your info.
Take it to a real shop and pay for the check out. Autozone's a ripoff anyway. JUST BECAUSE you know the ';code'; doesn't mean you know the ';problem';
