An apparatus and method for a vehicle central tire inflation system (CTIS) produces a series of valve open signals in response to a demand tire pressure signal in which each valve open signal has a time period and a time space occurs between each open signal. The series of open signals terminates when the current tire pressure is at least equal to the demand tire pressure and upon termination, a count is made of the number of valve open signals. In each successive series of valve open signals, the time period is increased or decreased depending upon whether the previous count is greater or less than a predetermined count range.
