Great price, where did you purchase these from?Yes, it will come on. That said, you will have to go to a shop with a TPMS scanner to locate which TPMS is bad. Your smarts OBD reader probably won't give you that info.
If you can wait until you need new tires do it all at once while the tires are already off the rims.
I bought 2 NEW MB TPMS for $16 each including shipping for my new rear sized front rims and tires. I like having the same brand and model tires all the way around. Because the car the rear rims came off was a 2009 I'm not going to chance having to replace them later.
"Pay a little more now or a lot more later."
I can rotate my tires.
