Answers :

There are about 50 things that can cause this light to come on. You need to have your engine scaned with a code reader to find the problem.
#1 problem is a loose gas cap or driving with the gas cap off. If this is the case then tighten gas cap and the light will go off in a few days. If this is not the problem then you will need to have someone read you trouble codes. some auto parts stores will do this for free.
