My check engine light came on. I disconnected the battery and the light went off. It even passed the state emissions test. As soon as I re-start the car, the light comes back on and stays on till I disconnect the battery again. Any ideas as to what I need to look for to resolve??
If the CEL is yellow (not red), the most likely problem is a faulty seal on your gascap. Get another gas cap and see if that solves the problem.

had no idea it shows up in red for different problems. What does Red mean? I refuse to pay Toyota $40 to hook it up to the computer for that silly light anymore. AutoZone will check it for FREE.
A red CEL indicates some type of severe engine damage, like a sudden loss of oil pressure. Usually when it's red, your engine is already totaled.
A yellow CEL is 99.9% emissions related. You may not pass an emissions check, but it's rarely, if ever, serious enough to pull over and stop driving the car.
You can always take the car to Autozone (or other local parts stores) that offer free OBD reader service. I don't know if they only do OBD- II these days or not, but you can call and check.
Post the codes here and we can better help.
I had to replace the cap about 3 mos ago and bought it "over-the-counter". So the cap is fairly new. No luck.
