New Rims/ TPMS sensors?

[Yota_Rep]

Just got new rims for my 07 Camry. I only plan on using them in the summer. My question--->I still need lugs and valve stems for the wheels, are the tire pressure sensors part of a valve stem assembly or is it a separate component? Will I have to buy valve stems with the sensors incorporated or can the factory sensors be added to my new wheels? Thanks in advance for any info.

That's a good question, maybe someone will answer it in the other thread asking for the answers.

What do the parts/service folks at your dealership/place of work say?

I thought you worked at Toyota Dealership You need to buy new TPMs if you want to have summer and winter tires and they are in the valve stems.

Actually since I just got the wheels and didn't plan on mounting them till summer I haven't asked anyone at the dealership about it yet. Probably just as much knowledge on this forum as there is in our service dept anyways. LOL

tou will end up having two sets of sensors, and every time you switch wheels you will need to go to dealership and change the sensors ID in the Toyota ECM.

What I did I kept my sensors for the stock wheels, but nothing on the summer wheels.

I'm with him. Just be sure that when you take the wheels with the sensors in them off be sure to mark on it somehow what side and position the wheel was in. The TPMS sensors have ID's on them to indicate which position they are in and mixing them with throw codes.

I might also mention that I see class action lawsuits in the future in regards to the TPMS sensors. They've basically designed them so that only the dealer will able to reasonably do tire rotations since the computer will be reprogrammed and I imagine that the cost of a tire rotation it gonna go through the roof because of this.

What? You telling me that the TPMS sensors has to be in the same side and same positon that the wheel was in prior to the wheel change? That is soo gay!!

Yup, that's what I'm saying. Each sensor basically has a serial number on it and is encoded to that position on the car. Every tire rotation will cost you computer time too....

I don't think so. My wife's Sienna has the TPMS system and we've had 2 rotations done at Merchant Tire without an issue (that I can recall).

Not true, you just have to pay for tire rotation.

If you read the owner's manual, there is a procedure to reset the system after tire service. I've have done it myself with no problems.....although I will add that my light always comes on now when the outside temp drops below 32 degrees F. I had my tires rotated at Town Fair Tire in NH, they said they can reset the TPMS for $20 and said the dealer would do it for a lot more, but then told me that the owner's man tells you how to do it. So naturally, I did it myself.

Now I have a cold weather issue and the dealer says the light will come on because of the pressure drop with the cold weather, but if its always around freezing temp, wouldn't that make the TPMS system useless and defective? Even after driving 30 miles the light still stayed on. I think the TPMS is BS anyway, what good is it gonna do when you have a blowout at 70 mph!?!? I always do a walk around my car every so often, can't help it I detailed cars for many years and am paranoid about anything being wrong!

The Automotive/Tire industries had better work out any issues with the TPMS or there might be some opposition, but from what I've researched, the US Gov is the driving force behind this system and DON'T you dare oppose the MAN!!

Interesting, my light hasn't been coming on with the weather changes. Sounds like you might be getting a bunch of smoke blown up your booty.


I read in either the owners manual or the service manual that if you rotate the tires the computer needs to be hooked up and the ID tags written down as they pertain to the tire location and once rotated they needed to be adjusted accordingly.

Strange, I will reread my Owner's manual, maybe I misunderstood it. Anyway, I will use this cold weather situation to have the dealer reset them properly them.

When you reset it, as th emanual says. all you are doing is reseting the threshold pressure. The sensors will detect the difference in pressure, not the actual pressure at a given time, for example if you reset your set and your pressure was a 32 the light will come on once the pressure drops to 6lb (??) under the set value of 32psi. .If you reset it at 25 psi then the light will come up once the pressure drop 6lb under 25!. Read the manual. The sensor doesn't know the actual pressure on tire, it will only "see" the difference in pressure.

If you change your sensors you need to input the sensors ID in the Toyota ECM, to do that you need to have a Toyota programmer for the ECM (cost a lot of cheeseburgers). There are other vehicles that you just reset it and thats it, NOT with the Camry you need the ID in the ECM to have communication.
