Tire Pressure Warning Light on 2007 Chevy Suburban

[PSU1999]

Does anyone know how I can turn this off? It usually comes on about every 3,000 miles and when I take the truck to the dealer for service they reset or turn off but this time it came back on much sooner. The only instructions I can find are for re-learning the sensors but I didn't rotate the tires so I think they are in the same position. The vehicle is saying the pressure is low but when checked with a manual pressure gauge its ok.

I've run 80 psi in all mine on my Ram and lite stays on.

The TPM in my Ram is triggered by the difference in the pressure of the tires. I think it is 4#, In other words if 3 are at 40# and one is at 45 the monitor will trigger.

First I would check the pressure in all the tires, not just the one the sensor is reporting. If they are all OK, then the sensor in the tire needs to be replaced. If you do find a low tire and it's not the one being reported, then you will have to go through the relearn procedure.
