First post, I apologize if I am bad at this.
Bought a 2007 Grand Prix GT awhile back. Got new tires with it, and recently got a tire rotation. Got a TPMS light on and Service Tire Monitor System on the DIC like a week after the tire rotation and checked all my tires but they were fine. I topped off the rear two which were a little lower, about 29 psi and I put em at 32. I started the car only to be met with a flashing TPMS light which I believe indicates a TPMS malfunction. The problem here is that I bought this car missing TPMS sensors on two of the wheels, the two front right now. I am sure that is whats causing the TPMS light but I am unsure how to reset it and if that will even work. I looked through the manual and only found a matching process, nothing about a reset for malfunction. Thanks in advance.
