The pressure sensor on the rims is a little electronic box INSIDE of the rim (or sometimes on the valve) that senses the tire pressure. If you had your tires worked on, they could have knocked it, and it might be malfunctioning.
On Toyota applications, the reset procedure is fairly straightforward. Turn the key on (engine off), then press and hold the RESET button until the flashing TPMS warning light goes off. Or, if it is not flashing, hold the RESET button until the light flashes three times. Turn the key off. But the relearn procedure is not complete until the vehicle is driven at 19 mph or faster for at least an hour. During this time, the TPMS system may not be able to detect a low tire, so make sure all the tires have been inflated to the correct pressure before the vehicle leaves.
The sensor looks like this:

Thanks everyone. I'll try the reset procedure first and then check out the batteries.
we bought a used 2007 Toyota Rav4 in October 2014.. in May the low tire light came on we put air in the tire but not sure if it was enough air. The tire light went off. The tire light came back on several days later. I took the car to Bedards and had them inspect the tire. I was told that the rear TPMS sensor was leaking. I was told that ETHOS does not cover TPMS sensors. I have the Summit Platinum under the High Tech System under what is covered it lists driver information gauges/indicators relating to the operation of the vehicle. Wouldn't a leak in the tire sensor be a safety issue especially if on a long trip when driving after maintenance hours. I had Bedards call the Ethos line twice because the tech thought it would be covered with a 50.00 deductable then told me it wasn't covered. Has anyone else had this problem. $160.00 for one sensor seemed expensive but necessary. When I brought the car in for service the low tire light was not on at the time.

same problem, my car supposedly only had 14 miles (2014) Murano ( Nissan), told sensors not covered?
'10 ram, 2500. Tpms still comes on after I reset the code. Tire pressure is fine literally. In fact, the other tires are lower in pressure. Normal pressure is @70 psi. The tpms is flashing @66 psi. But the other tires read 64psi and yet the 66psi is the one flashing.
I have a 2007 Lexus ES 350 and I've had a low air tire pressure problem just recently I filled the tires with air and the light went off then it came back on i bought a tire gauge and I had too much air in all the tires so I reduced the air and the light came back on so I took it to a friends mechanic and he told me I need a new tire sensor so I priced it for $100 dollars so I took it to Mavis and they tested the tires with the computerized tire tester and they confirmed that I need two front tire sensors and I need to have the sensors programmed to the tires and I have to take it to a Toyota or a Lexus dealer and that's gonna be very expensive.Now each tire is supposed to be 30psi.
