Hello! This is my first post so I apologize if I suck at this.

I bought a 2007 Grand Prix GT that was missing two of the TPMS wheel sensors. I got new tires when it was time to switch and recently got a tire rotation. The car threw a TPMS light at me and a Service Tire Monitor System on the DIC. I checked my tires and the pressure was pretty normal all around the board, but I topped off two that were a little lower. I started the car up to see if anything changed and this time the TPMS light was flashing which I believe indicates a TPMS malfunction. I'm sure that its the two wheels without the sensors that are being dickheads, but I have no idea if I can just reset the TPMS and tell it to **** off (I didn't even get to reset it because everything online that I tried didn't work, and the manual only lists a matching process) or if it will just come back. Thanks in advance boys.
