Duh. I looked in the manual and there it was. I didn't realize they showed that in there. They DO have them strapped to the wheels like the first aftermarket kits that we had at Goodyear when I worked there seven years ago. GM and Nissan have the sensors incorporated with the valvestem. I assumed they were all like that now. Thanks for enlightening me. That's cool. When I saw the rubber valve stems, I just assume we had the TPMS that worked off of wheel speed. The actual sensors inside the wheel TPMS are more accurate.
