I'm looking to replacing my TPMS which I have 2 of them dead. I've been searching the web($75-190 a piece), local shop($115-365 a piece). But they all seems to be way over price and some of the sensor look cheap too. I came across this site ITM AUTOPARTS | ITM Autoparts Inc. is a wholesale distributor and importer of internal engine components for passenger vehicles and light trucks. We have over forty years experience in the automotive aftermarket.
And found these sensor. They don't look cheap and are well priced.
It sounds like a good deal to me, a set of 4 for $172 on ebay.
Has anyone try these TPMS?

 

I work at a tire shop the TPMS is a tire pressure monitoring sensor. All they do is tell you if your tires are low on pressure. Have you checked your pressure? Have you seen if the are just not linked with you computer? You might try those first before blowing a bunch of money on the TPMS sensors you don't really need them. You might ask if they can reset your computer so you don't have to have them. Then you just have to check your tires every once in awhile
