".....I guess I will have to read the sensor part number on the vehicle we purchase in order to know which one to get?"

Make sure the sensors that come with the car are working 100% first. Then use that part number.

Yeah that's going to be the best way, and we luckily have a good Autel scan tool to read it.

Hi all, just throwing in my 2 cents, I had the "dashes" issue on all 4 wheels. Occasionally I would get readings, then nothing, sometimes the exclamation point light then not. I finally found the tmps reset button way under dash, did it quite a few times but always ended up with dashes. Was getting worried because have read around $400 each at dealer. I took it in last week and he came back pretty fast and said we "rebooted" and they work fine. Thought was strange but was relieved. I told him I was tempted to unplug one of the battery terminals for a kind of reset and he said no don't do that lol. Anywho, I also asked him can't I reboot it myself and he said just bring it here. All's well!

Is that different than just using the recalibration through vehicle settings? I had a similar scenario with my wife's RX just this week. I topped off all four tires - then driving home I had the four dashes - never saw that before. I though perhaps a huge coincidence that a sensor battery just died as I was filling the tires. Couple days later she has the dreaded flashing then solid TPMS lamp - usually indicates problem with system - bad sensor etc. (I checked the tires just to be sure and they were all at 35psi so no issue there). I did the recalibration and now getting the proper readings, no light and so far so good. Her RX is seven years old - I suppose sensors can go bad at that age.

I've read that they last generally 7-10 years.

No they did not! I wondered if would... Think that was normal to have no charge or I got lucky that day?
Will check the calibration process once home and can access my manual, ty!

LOL! Dealers usually don't do anything for free, unless warranty of course. That was nice of them.
