Go to autozone...they do them for free The code checking that is

Did you try to reset you're ecu???

How do you reset the ecu. are there any precation???

Just take it to Autozone they will tell you why its on for FREE

Disconnect the battery and let it sit for a little bit. Also clean out the MAF sensor and see if that helps anything. The celica ecu is incredibly sensitive so the littlest thing will throw a CEL

I had the same problem before, and my cylinder heads were bend... I would get that check as soon as possible

do a combination of what everyone said.

disconnect your battery cable for a bit and see if the light goes off, if it goes off then there isn't anything really wrong with the system, mine went on because "bank 1 too lean" basically because i have a CAI. but if it comes back on in a short amount of time take it to autozone, then when you know why it's on, take it to a mechanic.

my advice is to always do what you can to correct the problem before you have to start paying other people to work on it... personally...
