How to turn off Check Engine light on 2004 Lexus ES330? Had Autozone hook up computer and it said the the gas cap was the problem. I tightened cap as much as possible but light still on.

I found this on another site after looking for the same solution

1. With your car OFF, place your key in the ignition and turn to "On". Do not start the car.
2. Find the odometer button and press until it reads the total odometer setting, (not the Trip A or Trip B setting).
3. Turn the key to OFF.
4. Place your finger back on the odometer button, press and hold. At the same time, turn the key back to "On".
5. Hold the odometer button in until the MAINT REQD light goes out...should take about 8-10 seconds. I found this on another site after looking for the same solution 1.
