I presume you have checked that the pressures are all where you want them. My car doesn't have TPMS but my wife's does (car not here at the moment, sorry) but I have never had a problem doing the reset according to the instructions in the manual. The other question would be: Did you just get snow tires put on? If so, did they reinstall the ORIGINAL sensors when they put the new tires on the rims? If they put in NEW sensors, they will NOT work until you take it to Toyota and have the sensors registered to the car's computer. I don't think just any old tire place can do it.
I followed the suggestion of the service manager at a Toyota dealership in Ann Arbor ........ simply pump the tire up to about 50 to 55 lbs and wait for a minute or so and then slowly release the tire pressure back to what you want . I run between 38 to 40 . This over inflation method works for me .
was the car on when you pressed the TPS reset button? how long did you hold the button down (4,5 seconds?) is the car inside a garage, or outside? are you burried in snow, with the tires covered with snow and ice? or warm and dry inside a garage? what pressure are the tires set to?
Also it is possible that the spare tire may have a sensor too. Check that if you're still having the problem
I once had a Toyota with TPMS light on that would not reset with the button and such. I used Techstream software and cable to turn it off. The old TPMS system was better; it involved going around the vehicle using a pressure gauge once in a while.
Possible.....sure. But I don't think that Toyota EVER did that with any of it's models. And I hope in the 13 years since this thread was started, that they figured out what to do.
I think the 2009 has a small donut spare with no TPMS, but yeah sometimes the spare can trigger a warning.
Since somebody else opened this old thread.............. If it really IS just a low pressure alarm, driving a few miles after adding air might be required. It also might have been triggered by a failing sensor/transmitter.
