Tire Monitoring System?

**jksandyZ71** · 08-23-2009, 12:15 PM

Can anyone tell me what this means when it pops on the info display? The manual and my Haynes book have nothing to tell me what it could be. My guess is there is a system or censors that check the air pressure in the tires through the trucks (2005 tahoe Z71) computer. But when I checked the tire pressures they are all within 1-2 psi of each other. Anyone got anything?

Each sensor has a battery and probably what's happened is one of the batteries is getting low. Also your owner's manual is a much better source of information than the Haynes manual.

Many people don't this but there are certain procedures covered in the owners manual that are not even in the factory manual let alone the Haynes and other non OE manuals.

I had the same warning come on. I had recently purchased aftermarket tires. I took it to the Chevy dealer who scanned it and told me one of the sensors was not transmitting. I took it back to where I got my rims from and they replaced it for free.
