Air pressure indicator light
Yesterday my air pressure indicator light went on in my 2007 es350.The manual indicates that if it goes on and stays on for more than a minute there is a problem with the light itself, not with the air pressure in the tires. I checked all of the tires and even put some additional air in each to see if the light would go out, but it didnt. i live 80 miles from my Lexus dealership and dont want to go all the way over there for something so minor, and was wondering if anyone knows what could be causing the problem and how i might be able to fix it myself. Is there some fuse that could be involved etc.?Thanks for any help you can provide.
Your owner's manual contains detailed instructions on how to reset the TPMS system. There is a button on the very bottom of the dash just to the right of the steering column. If you can't find these instructions, post again, and I will detail them for you.

The spare tire does come with the car with a tire pressure sensor even though my AZ selling dealer service rep did orginally tell me that it did not in 2007. I doubted his advice and went home and took a little air out of the spare to test it. All five have sensors and if all of the original poster's tires are good his spare is probably low.

My wife's 2008 ES does not have sensor on the spare
Also, if the tires were first set with the pressure too high, the TPMS system needs to be reset when the tires are correctly inflated. My wife's car came from the dealer with over 40lbs in each wheel. When I put in the proper pressure, the system went off. I reset it, and all is fine.

My 2007 model built in 2006 has a sensor in the original spare tire. All five have to be in the proper range or the light will illuminate.
If the air pressure in your tires is correct then you probably have a bad sensor. I had one of my sensors go bad and once it was replaced my light problem was resolved.

Do you folks have a full size spare with an alloy wheel, or a donut? My wife's car, with a donut, does not have a sensor on her spare.

Thanks for all the helpful and informative replies. I will check my spare .Have had my es since july,2007.. I dont recall how much air pressure my tires had when i bought the car,but having driven it for over 2 years, i figured the sensor is bad. I just hope the reset works so i dont have to drive 80 miles each way to get the warranty work.
thanks again.
thanks again.

i followed the instructions in the manual on how to reset the TPMS but the light didnt go out. i guess the indicator is faulty.
sircharles...are you saying that if i overinflate the tires the light will go out and stay out?I put addl air in each tire and it didnt change the TPMS light..it stayed on.
Thanks.

This is what I did:
Got in the car and sat behind the steering wheel. I pushed on the Engine Switch 3 times. Then I reached down and held the Tire Pressure reset switch for a few seconds as I watched the light blink. Then I released the button.
At that point, the Air Pressure Indicator Light went out. Waited a few seconds, started the car to see if the indicator light was on. It was not.
I restarted the car to check again. Success !!
