The computer has detected a problem with the emissions controls or something that effects emissions. Fix ASAP. It also can detect when you have not put your gas cap on tightly. The absence of a vacuum in the gas tank will cause the check engine light to come on as well. -Voice of experience. Possibility: When my Bravada had a "check engine soon" light come on it was because the O2 sensors were bad. The next time it came on was because when I had the fuel tank replaced the mechanic forgot to plug a sensor above the tank back in.
