So I had the tires replaced on my wife's 4Runner the other day at discount tire. In the process they broke three of the four sensors. They replaced them all for free but the system is still having problems. The TPMS light stays on even though all five of the tires are at 32 psi. I took the 4Runner back in to have them reprogram the new sensor id's into the computer. The light will turn off momentarily but it comes back on after about 30 seconds after they disconnect. They do have the correct computer to manage Toyota TPMS systems. I have a broken wheel stud also. Is there anything I can do to reset the system? I might disconnect the battery and see if that helps. I don't know if they over inflated the tires to activate the sensors or not (seems like I read somewhere this was part of the process) and then brought them back down to the normal range. Thanks for any help or input. Oh yeah the new tires are a litter larger than stock so I don't know if that makes a difference.
