Where can I get new set of tpms besides dealerships?
04 sc

 

You can try E-bay. I just checked and Rockauto does not list the Denso TPMS's for the 04 SC? I do not believe the TPMS's sensors listed on Rockauto will work.

Also keep in mind that you need 4 different sensors. A Red, Blue, White and Gold/Yellow. They all have different part numbers. You want to get the latest one's which end in 1's. Like 11, 21, 31,41. The older issues end in 0's like 10, 20, 30, 40. It does not matter which wheel you install them in but you will need access to Techstream in order to program them. Here is a link where I bought a set for my sons 05 SC.

Can anyone tell me what the result will be if I install new snow tires without the TPMS valves. I have a 2007 model. Is there a light or alarm? Can it be turned off or is there a work around?

Yes the yellow light will come on and stay on because the system cannot find all 4 sensors. Your 07 does not use the same sensors that the 06's and older SC use they are not color coded. So you could get 2 new sensors and mount them in your snow tires but you would still need to program them to the system I believe.

There’s no way to turn off that annoying yellow light unless you install the sensor and program them to your SC.

Thanks I thought that is what the steps were.

There's a button behind the glove box door (at least that is where it is on a 2002) for a second set of tires so that you can switch back and forth between the 2 sets of tires (like winter and non-winter tires). So if you were to add TPS to your winter tires and register them with your TPS module, you would just flip the switch to use the 2nd set and then turn that off when you install the non-winter tires back on.
