Toyota Repair: toyota avalon 97, toyota avalon, diagnostic fee

Question
can u tell me what the problem the check angine light mean i just notice it came on

Answer
There are many reasons for the check engine light to turn on, when this happens the onboard comnputer(ECM) haas detected a malfunction in the engine or transmission control system, the first step is to have a diagnostic scantool connected to retreive the trouble codes, the toyota dealer can get those codes for you for a diagnostic fee and make a recommendation on what needs to be done, most autoparts stores such as autozone will get the codes for you at no charge, when you know what the codes are and you still need my help then please post a follow up with that information.
