You need to have the computer codes read at the dealer or a parts store ( lots of them will do it for free ) the issue that your truck is having may have nothing to do with the gas cap. If you did have the codes read and a gas cap was the answer then disconnect the battery or better yet remove the ecc fuse for about a minute to reset the computer and see if the problem returns.

What are the reasons of service engine light in 2000 mirage?

Could be about 100 different things but first thing to check would be your gas cap If it is loose or not sealing it will turn on the light. Note If that is the problem after it's tightened light will still stay on for 2-3 days have you changed the air filter. I have a 99, the light came on because the air filter needed to be replaced.
