Abstract
A method for fault identification of gas sensors exposed to a gas mixture is disclosed for gas sensors having an output that depends on concentrations of two gas species in the gas mixture. The method includes receiving output signals from two such sensors, processing the output signals in a controller that implements a model of the sensors so as to identify a fault in the first gas sensor or the second gas sensor; and providing an indication of any identified faults.
