The check TPMS system/function error light came on in my 2010 Touring. I took it to discount tire and one of the sensors is bad. He quoted me $60 per sensor, installed. He reccomended that all 4 be replaced together. I'll start with just the bad one for now, but before I do, is $60 reasonable? is it an easy job to do myself with not much experience if it saves a significant amount of money. $60 alone doesn't seem bad but multiplied by 4 is a big difference . Also, in the meantime is there a way to disable the light from my dash? He confirmed the tires are fine, it's just the sensor that's out.
