I bought a car from a use car dealer. At first the engine light was not on. By the time I brought it home it turned on. The dealer said its not a big deal however Toyota said I need to get it check out or bigger issues will come up. Does anyone know how to reset the engine light or tell me whats wrong so I can tell the dealer that he sold me a bad car and he needs to fix it?
 
It could be several different things. Could be a simple as a needed oil change. Could be serious. Needs to be checked.
 
The only way to really tell is to have a mechanic run a diagnostics on the car.

Basically he will hook it up to a computer and scan the chip in your car, and an error message will pop up telling him what is wrong, and why the engine light is on.

Most times is the oxygen sensor, if the car starts, and runs good, most likely what it is.

However, the dealer should be taking a look at the car for free, and fixing whatever problem you are having as you JUST bought the car, DO NOT LET THEM PUSH YOU AROUND, they will try to get away with whatevery they can.

Running a diagnostics through another mechanic will cost money, and honestly, why should you have to pay a DIME when you just bought the car!?

I used to work for a car dealership, and trust me they are ALL shady, and will try to get away with whatever they can, talk to a manager.
 
Engine lights can be a sign of any number of problems. The computer will have a code in it that a special computer is able to read and tell the user what the exact problem is. As Mike said, you can take it into Autozone or Pep boys or even the toyota dealer and get them to check the code, they will then be able to tell you what is causing the problem and if it is a concern. They will also be able to reset the light if it's not a big deal.
 
Sound like your emissions system is on its way out - not cheap to get fixed - new cat converters will be needed.
