I ended up replacing a wheel (long story) and decided to replace the TPMS too. I ordered one new OEM TPMS along with the wheel from mobile service (no SC in my area) and had the TPMS installed and tire mounted/balanced at my independent and threw the new wheel on the car. I reset the TPMS under service but the new TPMS isn't registering. Over the last 3 days I've made at least 4 drives over 10 miles and I get the "Tire pressure monitoring system fault" and none of the 4 corners register. Then after 10 miles the 3 existing TPMS register but the new one doesn't. Every drive starts the same way with none of the 4 registering and then the 3 old ones registering after 10 miles.
I've tried taking about 10psi out of the tire and putting it back in. The car has slept between drives. I've reset the MCU. Do I need to give it more time, or does it sound like I've got a faulty TPMS? Is there anything that the installer would have needed to do to "turn on" the new TPMS? Appreciate any feedback that anyone has.
