Check engine light on , help

Hi guy's just joined the forum so this is my first post. I have a 96 jetta 140000 km in good shape with one problem. Two yrs ago got a DUI meaning the car sat in the drive way for 2 yrs. I may have started it up three times , each time having to throw the battery on the charger the night before. She always fired right up with no problem , however just the other day i went out to start her no problem but the check engine light came on. First time this has happened. Mechanically the only problem i know of is a leaking exhaust with a whole in the resonator. I had the exhaust issue right up to the day a parked her never seeing the light come on. Any info what to do or perhaps what the problem might be , Thanks

Any Local Auto Parts Store will pull the Diagnostic Trouble code for free, than come back to your Thread on AF.

get the code read....I would be willing to guess that it has something to do with an oxegen sensor, but check the code first.

Thanks for the reply , the most popular answer seems to be the oxygen censor. As far as getting the code's read for free , Canadians might be nice but were tight asses and likely make me pay. My next question is can i test the censor myself before i bring it in ?. I'm more then capable mechanically and have the means to do so just need to be pointed in the right direction. Thanks , hit me up with the how to.

Oxygen sensor is likely, given what you've said. And you really might be surprised at shops. I know I'm not in Canada, but where I live, I can think of 4 shops that would run a scan for free - and 2 of them are just autoparts stores.

You can buy an OBD reader, but I think 1996 was the last year for OBD I (and most modern cars are OBD II) so you may have to look a little harder to have the code read.
