Looks like at least one of my TPMS sensors have gone bad. Tire pressure is good in all tires, but I'm getting a blinking alert every time on startup. Any ideas on how to figure out which one(s) have gone bad?

 

A tire shop might be able to, or the dealer. If your car displays the 4 tire pressures and one of them is ***, you could adjust the pressure in the tires to determine which one is not working. If it doesn't display tire pressure, then I don't think there is any way to figure it out without going to a shop.

 

You can get it reset by a tire shop. Discount tires does it for free and it only takes a minute.

It seems like I get one that does that every few months. Not sure if it's just because they're getting older or what...but after they reset it then it's good.

I know they have a finite life span, but every time they say the battery level is ok.

 

Agreeing with NCSUPilot, but if you want a DIY solution,go to the WT section of the FSM, it outlines the process for both determining which sensor is bad and even the reset procedure. http://www.nicoclub.com/FSM/Maxima/2010/ The hardest part of the process was finding the white wire!

 

Thanks for the advice. I had new tires put on about two months ago and I expected they would reset the TPM but they didn't. My fault for not specifically mentioning it to them.
