Engine light advice

Well, my engine light came on. I reset it by disconnecting the battery, but after several starts, it comes on again. How do I diagnose the problem? The car does not exhibit any type of problem,.....so continue to drive I do.
Please advise. 1994e420
Thanks in advance for your advice.

take it to a shop and hook it up with a computer and they will tell you the codes and then you'll know whats causing your check engine light to go on... could be some sensor or something who knows

You could also make your own code reader by and figure it out yourself. 1 hour @ $130 at the dealership or $20 and 3 hours at home. Your choice but if you want to make you own reader just search the forum for "code reader" and you will find all the info you need to do it.
