I just got new rims on my black Touring and the shop that installed them says that the tire pressure sensor on my Z will not work with these rims.... So now the "psi" is flashing on my screen constantly! Is there a way to fix it or at least stop the flashing??

 

Try resetting your ECU. My TPS have been sitting in my garage with my stock wheels since January, and I've never had my low pressure light come on.

 

mine did the same thing. It didnt come on for a week and then it was either when I had the tps on the passenger seat or when my gas light came on that the psi light started flashing as well. Its still going.

 

It comes on only after a long drive for me (~90+min).
Some folks seem to get it more severe though.

You have to strap the sensors to your wheels to make them work.
