This past weekend I swapped out my 18s for a set of the 20" sport wheels with factory tires and sensors. For the first couple days everything worked as it should. Then yesterday the tire pressure light came on saying sensor error, now three of them are out today with one still working. Any ideas what is going on?

 

The sensor frequencies are different for 2015. The wheels you have either don't have sensors in them, or they are from a previous year.

 

these are off a 2015 and they worked when I first put them on.

 

Did you program them to your vehicle?

 

No I did not, what does that entail?

 

-MisInformation-

The TPMS sensor frequencies for the gen'12 (2009-2014) and gen'13 (2015+) wheels are the same (315MHz).

*The gen'11 (2008) are the band style (rather than valve stem) and operate at 433MHz.

The only difference between the gen'12 and gen'13 sensors (along with the shape) is the internal electronics. And that is why they are incompatible.

Detailed, how-to instructions are in the owner's manual.

(owner's manual) Don't have one -OR- would like a digital, searchable desktop document?

 

I tried it and it did not work almost let all the air out of the tires twice.

 

I'm not sure if something is causing an interference or what

 

Are you sure there actually are sensors in them??
