@troyphoto That is an expert answer.Typically tire pressure sensors only last 5-7 years. The easy way to check them is to pull them up on your dash. If any of them read with a blank or -- then the little battery inside has died. The batteries are not serviceable so the sensor has to go. I generally replace them every time I replace the tires. Find out what the OEM part number is, then Google search it. I get OEM sensors from Rock Auto for less than what I can buy them for from the dealer. I try to stay away from the Amazon el-cheapo sensors.
I've replaced all my valve stems with standard (no sensor) metal valve stems. I had an OE valve stem leak. I am compulsive about using my Craftsman digital tire gauge. It is easy with my Milton Double Seal Valve Caps. I'm old and stuck in my ways. I simply ignore the tire warning on the dash and stay off my lawn!
@kbkchooch Amazon does sell genuine GM parts, sometimes as low as 50% off list. You can find them by searching for the GM part number. And they do sell cheap Chinese crap too. I only buy genuine GM parts.
Brilliant!Did you check your spare in the trunk?
I forgot to suggest that a week or so ago when I hit something in the road. I pulled over within 200 yards of hitting whatever it was, and the tire was almost flat. I checked the pressure in the spare, 15psi, not good! Fortunately, I carry a battery powered compressor.
I don't know if spares have pressure monitors, but it is always good to periodically check the pressure in your spare.
I trust my tire gauge more than any sensor.
