What is required to reset a TPS light on the dash

What is your question?

after replacing all Tire Pressure Sensors the Tahoe drove fine for a while. Then the dash TPS fault light illuminated and has not gone off. All the tire pressure sensors are providing a pressure readout that corresponds to a manual pressure reading. I think I only have to clear the fault. I don't want to pay the dealer several hundred to get that done. Any suggestions or methods?
