Re: Tire sensors
I bought a set of sensors to go with my steel wheels/winter tires at Costco.
I had to buy a tool to sync them up, I think it was around $100. (Kent-Moore EL-50448 TPMS Tire Pressure Monitor.)
You just set the car to "learn" mode and go point the tool at each tire, going clockwise from driver's front all the way around the car. Takes 1min. It's a bit disappointing because there used to be a trick where you could let out 3psi of air to sync the sensors up, but that's no longer true with current BCM programming.
