My 07' just turned 113,000 miles on the odometer. The TPMS indicator lamp has blinked a few times in the past 6 months for short periods of time. Now the indicator lamp blinked continuously.
Purchased the vehicle in 2011 with 50,000 on the odometer and don't have any vehicle history. The brake pads and OEM sized Michelin tires appeared to be new from my initial visual inspection after purchase. Pleasantly surprised to obtain this much mileage/lifespan on the same set of tires, pads and TPMS sensors.
Did quite a bit of research on disabling the TPMS. Looks like there are few ways to bypass the indicator lamp and folks have had success. Per review of a Toyota TPMS electrical schematic, I was a bit leery to take this route due to the nature of solid state electronics and their complexities with system voltages & impedances. Plus, the indicator lamp is there for a reason. I, like many others check tire pressure often but there are times where time passes a bit too quickly and it is overlooked....especially during the frigid winter months. But, I'm always concerned about the wife when she drives the vehicle. She may not be able to sense a tire that's low on air pressure or slowly going flat while cruising down the freeway. Couldn't live with myself if she were in an accident due to my negligence.
Opted to simply replace all (5) TPMS sensors today at Costco. Grand total including tax was $312 ($45 per sensor + $14 to install for each wheel). I've purchased at least six sets of tires from Costco throughout the years and have had superior service. They seem to take their time to do the job right. Plus I like the fact they don't get overzealous with the impact gun. I watched them wire brush the mounting surface of each wheel and rotor in addition to wire brushing the wheel studs. They also use conventional torque wrenches and two separate individuals check the torque of each wheel. Nice checks and balance system.
