    Tires Plus reset the warning light after a diagnostic test showing that it was the gas cap. 1 1/2 months later I am stranded when the fuel pump goes out. Coincidence???

    I am the original and only owner of my 2003 Tracker LT and noticed that my check engine light goes on when gas cap is not on properly. Even though I replaced the cap 2 times and checked the tightness of the cap. It is annoying but really happy that's all it is.

    Solution: If light goes on, check gas cap and/or replace cap yearly. Very inexpensive.

    Please note, when check engine light comes on, first check gas cap then other issues. :)

    Computer sensor "check engine" light came on. Local auto part store computer check stated " to check gas cap". Sensor light went off.
