    I got 4 New Michelin Defenders put on my 2006 prius with 77,777 miles on the car. I had the tires installed at Discount tire.

    I got the whole package except I kept my old tires to save $10. I wanted also wanted to save the $24 on the TPMS replacement. They told me I needed to have the sensors replaced so the old plastic "doesn't break apart" and puncture the tire. I paid the $24.

    I have maybe less than 30 or 40 miles on the tires and the TPMS light was on solid after helping someone in a parking lot.

    I tried resetting the light with the button under the steering wheel. It starts blinking for a minute but still remain solid.

    They had the tire pressure at 33 and 35 or something but I inflated them to 44 in the front and 42 in the rear. Ran that way for the 30 or 40 miles now the light was on.

    I checked my tire pressure with my digital air pump and the front had 46 and the rear had 44(heat & friction from driving).


    I had my Dad try and ask them about the TPMS and they said all they did was "rebuild" the sensors for $24. They told me that was a "Replacement".

    I have a feeling they damaged a sensor and won't do anything about replacing them.

    I still have my original tpms in my '06, no problems. The tpms each have a serial number that has to be entered via techstream to your car. Your car currently does not see the original tpms and does not recognize your new ones.

    The discount tire never replaced the TPMS sensor, they said all they did was "rebuild" them. 30 miles down the road the TPMS light is on and won't reset. Are you saying after they rebuild the sensor that the car is not recognizing them?

    I believe the "rebuild" equates to replacing one or two O-rings. And yeah, seems like they cocked something up in the process.

    It might be the batteries would have failed soon, and they're not replaceable: your options are completely new TPMS, or replace with regular, non-TPMS valves, if you can get away with it.

    I'm beginning to really hate those things.

    If they didn't replace them then your tpms should still be recognized. They might have messed up reinstalling one or more or one of the sensors might have just died on it's own. The battery in each are not replaceable. You need a mini vci techstream code reader or take it to a trusty Toyota dealer for diagnostics.

    Thanks for the replies! I have a feeling I will need to get new TPMS sensors. It was odd that they were working fine before. Will see what they say.

    Same thing happened to me - got new tires, and now the TPMS light is on. Took it back to Goodyear and they said the battery on the left rear sensor died, and to replace it they have to order a complete kit, will cost ~$140. Is that what you ended up doing? Is that a reasonable price?

    Never let them replace the seals (rebuild) on your TPMS sensors. It's just a way to bump the ticket.

    Dont forget to try to the TPS reset under the steering wheel.

    Each TPS sensor has special button batteries looks to me they last about 9.5 yr @150k miles. It depends a little on miles driven as the TPS goes off to save batts when the car is not in motion.

    Basically for 2006/2007 cars we should probably advise folks to get new TPS units when tires are changed. Otherwise you have expensive job to separately replace TPS.

    My light is on now waiting for me to decide what to do. You can put tape over the light.

    If complete kit is 4 new TPS installed that's a very good price. You can get these TPS (non OEM) for $25-35 each on Amazon but then you gotta find a shop to install and program. So $140 would be nice price.

    I gotta call my tire shop to see what they say. My local car shop wants a lot of money to replace 4.

    You may have to take your car to Toyota to get your problem straightened out. If you do, after you see how much it is going to cost you, probably you will just do without a working TPMS system. I wouldn't let Discount Tire do anything to my car but that is just my opinion.

    Sorry I haven't posted in a long time. I ended up buying 4 used one on ebay. I had discount install them for it only cost $60.

    They tested the ones I bought and found 2 of the sensor had low batteries. They said they will eventually fail later down the road. The seller claimed they were new and never used.

    Next time, I will buy the ones for $114 brand new aftermarket.

    So far they are working but when they do quit, I will go new aftermarket.

    When the sensors cost more than aftermarket rims there's a problem. I would just let them fail, get regular valves, if you can get a shop that will do that.
