Abstract:
A method for validating a pressure sensor between a source of a gas and a pressure regulator that regulates a gas flow. The method includes providing a valve command signal and selecting a bias signal from a bias table. The method also includes comparing the selected bias signal to the valve command signal and determining there is a pressure sensor error if the difference between the selected bias signal and the valve command signal is above a predetermined threshold.
