How to Reset the Tire Sensors on GM Cars
by Alibaster SmithGM's tire pressure monitor employs a sensor inside each tire's valve stem. Reset each tire sensor light when you change tires or your tire pressure gets too low, causing the "TPMS" light to come on. While some GM vehicles have an automatic-reset feature, a manual reset can be done on all makes and models of GM vehicles that use a tire pressure monitor sensor.
Step 1
Press the "Lock" and "Unlock" buttons on your car's key fob at the same time. The car's horn will chirp twice.
Step 2
Unscrew the front-left valve stem cap.
Step 3
Press on the valve stem for a few seconds to let air out of the tire until the horn chirps. Replace the valve stem cap.
Step 4
Repeat Step 3 for the right-front, right-rear and left-rear tires--in this order. The system will be reset, and the TPMS light will shut off.
