Re: 2007 DTS TPMS Dash message "Serice TPMS System" 1 tire no reading??
yeah, that^^^ Don't cheap out and buy used or even 2007 OEM. Buy new ones. You have to break down four tires to install, re-inflate and then do the protocol to sync with the car. 2007 was the first year model that TPMS was required by the Feds. So you have to fix it or live with the message.Sounds to me it’s the battery and it’s time to change all four tire sensors.
