The air suspension pressure sensor sends a voltage signal to the air suspension module that corresponds to a pressure within the range of 30-180 psi. The air suspension module also uses this signal to verify that the proper amount of pressure is achieved in the air dryer within 23 seconds prior to opening of the inlet valves for inflation of the air springs.
