Hi, New to the Forum but not to Scion. I loved my 2005 XB and just bought a 2008 Silver XB. I have added the rear spoiler and TRD springs. I want to add new wheels and tires but I am having trouble getting the part # for the TPMS sensors. I have spoken to two dealers and neither has the part numbers. I do not want to remove the sensor from the factor steel wheels. I plan on keeping the factory wheels for winter use. Can anyone help me with the part numbers for the sensors? I have the wheels and tires picked out but need the sensors. Any info would be appreciated.

I will ask a friend that works for scion this week


also, do you know the bolt pattern and offset for new wheels for the 08 box

Insureit1

Thanks for your help. The bolt pattern and offset I have seen from other post on the forum are 5x114.3 with an offset of 40. There seem to be plety of wheel options that will work.

thanks

what i found out is the tpms sensor are the same as the ones in the camry.

tirerack sells them too. there are generic that are work great

a friend of mine has a gm product and went to discount tire. they sell them too.

Insureit1

great thanks for the info. I checked with tire rack and have no info at all on the new xb. They will not guarantee any fitment on the new xb.

I used the camry se with tpms for my fitment and i am ording wheels with them tomorro

I bought the TRD 19s and wanted to put the monitoring units in my new wheels...$500.00+!! Needless to say, they are putting the ones from the stock wheels in the new 19s.

u can get em at tirerack.com but i think it cost a grip

I heard rumors that TPMS sensors from steelies might not fit in the alloys, at least there are 2 different models of the actual sensors. Any input?

SquallLHeart

they should fit..

however after all that work... every single time you switch them out.. you ened to have a toyota scantool to reprogram the car to accept the new sensors.. which you will also need to ensure you have every single serial number from those sensors written down and stored properly.

that process alone is tedious... and regardless.. you're going to have to open up your stock wheels anyway to get the right numbers for when you put them back on.

zoltiz

You should be able to read the numbers without opening the wheels up. I replaced wheels on the Z (put '06 5-spoke18s instead of ugly-ish '05 17s) and the tech just walked around with the scantool reading the IDs of the sensors and then typed them in the scantool and uploaded to the ECU. took 10 minutes, I got billed for an hour - $125

Anyone know how to bypass the sensors all together. Seems like the cost is way out of line for the benefit.

There must be a way to disable the whole system...either via OBD II or unpluging the reciever somehow.

I am not sure if there is/is not a way to do it. I know it is illegal to do it however.

Also, any confirmation on using camry sensors ? I know there is no "generic" listing for the xB sensors. But I don't want to try camry ones unless they are known to work.

Here's an idea I got from my bro, drill 3 more holes in your spare rim and install your sensors there.

Genius. I'll try it. It may also be possible to put all the sensors in a small pressure tank and add some air.

Does anyone know if the sensors work off of pressure difference, or is it based off of actual PSI? The reason I ask is because my Xterra TPMS system only goes off when there is a large difference in pressure between the tires (one at 10psi and the rest at 30 for example). You can put all the tires at 2psi and it won't set it off. If the xB system is based on "difference" then in theory you should be able to keep them in the glove box and call it done.

BloodHoundFan

I don't know if this is fact. But I was reading some information published on Toyota's TPMS and it mentioned the difference in how a low pressure tire turns/rides compared to the others. It made it seem like it wasn't actually going off based on just PSI but also on the unstable rolling of a lower PSI tire.

zoltiz

Previous gen TPMS ('05-'06 tC) was ABS-based - so it was measuring rotation speed of the wheels and looking for the differences. Modern ones ('07 tC, '08 xB/xD) have actual sensors in the tires that look at PSI.

You can always just drive around with the little light on like I do. I don't even notice it.
