Should have an OBDII connection under the dash on the drivers side. Looks like an elongated computer port, probably has a cover on it that says OBDII. You can buy a code reader from an auto store like pepboys for around $100 i think. Just a side note, usually if the car is still driving ok and not acting weird, it is an emissions sensor.

I have a 2003 Toyota Avalon. My toyota problem is the check engine light that came on.

Hello. Welcome to FixYa. Please allow me to assist you. The Check Engine light comes on for many, many different reasons. The most common reason is the gas cap being loose. I would check the cap for being loose. If it is loose, drive the car for 10-15 miles to see if the light goes out. If the cap is not loose, you should go and take the car to someplace that can scan the car's computer to get the codes, the reason for the light being on. Autozone stores do this for free. Get us the codes, and then we can isolate your problem better.

The check engine light keeps coming on for a 1998 Toyota Avalon.

Had the same problem!

Your Computer won't reset. Now don't freak out their is a fix.....

Your computer is out, and needs to be replaced. their are three ways to resolve this. Buy a new computer (about $1200 plus aprox. $200 labor), find someone who can somehow get the computer to reset (??? this could cost about $600). Not a good choice.Their is another way, but it can't be posted. It is a total fix, but not even related to the problem. I know a mechanic for the company and.......

Don't take a chance on what the dealer says, when the engine light comes on take it and have the code read and it will tell you what is going on. The light must be on at the time the code is read though or it won't tell you anything. Most auto parts stores will do it for free.
