Just as a reference and for those who are curious, I took some pictures of the tire pressure sensors when I was swapping mine out to mount my new wheels.

FYI:
- All 4 sensors are coded into the ECU from the factory, so that even if one is missing, the tire pressure warning light will come on
- Along those lines, even if you swap out your stock '07 wheels with another set of '07 wheels, you either need to re-program the new sensors into the ECU (via $$$ @ the dealer) or swap them out when you're mounting/balancing them, which is a PITA

Here they are:

could you post the pictures up again?

I am changing wheels very soon and need to know if they will fit the new wheels!

thanks!

 

Jigga, i asked the dealer and they said the sensors will fit 16.17. and 18s fine... 19s are a pita but can be done. and they hadnt seen an 07 on 20syet to know if they would fit. if you cant get it to work, bring it to the dealer.. my dealer said if i brought rims and tires he would swap the sensors mount balance the tires and just charge me for a rotation and mount/balancing... under $50...

 

thanks for the info orange

i wonder if my dealer is that nice.

I'm curious on how they actually plan to mount the sensor on the wheel.

ready to mount my rims!

 

At my work when someone brings in something low profile that needs sensors, if we cant get it into the stock valve hole, we have these band and bracket kits. You basically end up strapping the sensor to the barrel of the wheel via a metal band/bracket. Not our preferred method, but it works on wheels where that is the only option...
