Check your gas cap. My light would come on whenever the cap wasn't tightly on. Turn it until it clicks three times. You may also need a new cap if the seal around the cap is bad.
What causes a warning light to come on saying check gas cap on a 03 Mazda tribute?
the check gas cap is a separate, specific dummy light from the check engine light, although the two may be related. I've found that the gas cap on the 03 tribute is different than any other on cars I've owned. It is pressurized, and you only turn it 1/8 of a turn to open it (counter clockwise) and 1/8 of a turn to close it (clockwise, pushing down on it a little, and turning it until it clicks). I did not install in properly the first couple of times I put gas in it, and I got the gas cap dummy light the first time, and a check engine light the next (not having the gas cap installed correctly messes with the emissions system - which is what the check engine light indicates). Both cleared once I figured out how to use the gas cap properly.

Your engine light on your dash came on and stays on .we just had the oil changed?
There are many causes for the "Check Engine" light to come on. Most are related to the pollution control components of the vehicle. The primary cause, however, is the gas cap. Be sure that when you put it back on, you tighten it right up to the point it clicks then turn it another half turn (it won't hurt the cap). If the gas cap is on tight then take it to a mechanic and have them hook up to the computer to read the fault codes.
What would make Mazda mpv check engine light is on?
one of the most common causes is the gas cap not being screwed on tight enough, or somehow becoming loose (such as a worn out cap). It will not reset right away (turn the light off) give it a day or two of cold starts and it should turn itself off.
