for a couple days my TPS sensor was lit, I had to add 3-4 psi to each tire. At first I thought it was my check engine light before looking up what the symbol meant in the manual. After inflating each tire to 35psi, the light went out after about 5 minuntes of driving.

If you do use air when you have your next service at the dealer ask them to drain and refil all your tires with Nitrogen, my dealer stated there was no charge for this service.
