I had a Mazda some years ago with the check engine light on for years. Finally, I decided to handle the issue with a well- placed piece of duct tape on the dashboard. Voila, problem solved!

we put a piece of electrical tape over the check engine light in the truck.

mike, typically if you unhook the battery cable, it will reset the check light for a few days, but then it comes back on.
and i have to wonder if the 'mechanics' working on my car know that. oh, hey, the light's off, we fixed it. but in fact, they just reset it when disconnecting the battery. and i know they're disconnecting it, because clock has to be reset each time we get it back.
