My 2012 Honda Civic had 2/4 of the stock TPMS valves leaking air. The dealer says this is a common thing, so I've seen others report that they "buy an Autel product". So did I! I have an Autel TPMS Relearn Tool TS408 along with four packs of these MX sensors and boom, TPMS in the car is happy! No more leakage either! High level process: 1) Install and update the MaxiPC software on your PC or Mac2) Run the MaxiPC package on your PC or Mac3) Connect and update the software on TM4084) Copy the hex code from old OEM TPMS sensors5) Transfer the hex code to new sensors Autel TPMS6) The TPMS lights in the car are off!
