- Some sites say they last 10 years? On tire rack installer price list it says $5. Is it that cheap to program to ecu? Or just to install the sensor? The sensor is like 50$ discount tires said like 60 $ each with install.
well if yours died, I wouldn't be surprised. From what I remember, they are lithium batteries. And those can and do die at about the 5-6 year mark. Just because someone got 10 years doesn't mean everyone will. Like that one guy I heard got 7 years on a stock battery! I got 4 and was lucky.
So discount is saying they'd charge $5 extra when installing tires? Sounds like they're just making money, since it screws in just like a normal air valve, just has a small body resting in a dedicated space on the wheel. but hey it's just their labor/time I guess.
It's not tough to program a new one. Most tire shops have the programmer to have your ecu/computer recognize the new ones. I've never heard of anyone replacing the battery on these.. Big question is WHY ISNT THE BATTERY REPLACEABLE!! That's like throwing our cars out because the main battery in the engine bay went bad! dumb!
here's the part number and yes I would buy the Toyota one!
Reading that website, makes me think who cares if your sensor goes bad on the tpms system. It's just an idiot light, seriously. It's just trying to tell you that you were too lazy to take out an tire air gauge and check the air pressures in your tires. If you don't have the money right now, just let it be dead and leave the dumb light on, on the dash. It will NOT affect your abs, since abs is measured by a separate abs sensor on the hub area. Just giving you some peace about this, that it can wait. Some don't even put the tpms inside winter/snow tires and nothing bad happened to them. It's just a government over reach for overreaction to the ford/firestone under inflation issue back in the late 90s/early 2000s. And in that case Ford went against Firestones recommendations and told their customers to put LOWER air than what was safe because Ford was too lazy to re-engineer the suspension, so they lowered the air pressures to compensate for it.
So if you don't have the money to replace them right now, don't worry about it, just be aware you'll have a light on, on your dash. And just get a nice digital tire gauge and check the air pressures yourself! We're scion owners, not camry owners! lol we check things!
