How to i get the "check engine" light to disappear?
There is no dealer in my area and I don't have a dealy to read into the computer system in the car. I have a 98 c70 volvo which has the ever reoccuring problem of having the gas cap trigger the light to come on.

Any ideas??? Please please please help.

Worst case scenario can I simply remove the bulb from the"check engine" light??????

Go to your local auto parts store (i.e. Pep Boys, Autozone) and they'll read and reset your codes for free.

Just had a mechanic do it. He told me to unhook both terminals, and then touch them together for 15 seconds, or so, and then rehook them to the battery.

I read at this site in another thread that this is potentially dangerous to the vehicle electrical system. Anyone else care to weigh in on this?

If it is always the gas cap wouldn't it seem logical to replace the cap rather then shoot the messenger (light)

Many parts houses will read the codes stored in your computer but in many states it is against the law for a parts house to reset the codes. If you do get it reset without fixing the problem the codes will come back.

If the parts house will not read the codes go to a emissions check station and they will usually read them for $10. Or go to a Tune Up Clinic and pay $25 to have them read - they will also repair for additional $$ if you are not comfortable working on your car. For whatever the reason of the code you do need to get it fixed.

It was here back in May or June.
Help keep MVS on the web -> click sponsors' links here on MVS when you buy from them.

Also -> Amazon link
