FIELD: machine engineering.
SUBSTANCE: method for controlling the exhaust gas sensor connected at the engine outlet is proposed. In one of the embodiments the method contains an indication of the performance degradation of exhaust gas sensor based on time delay and linear section of each measurement of the set of exhaust gas sensor responses collected during entry into or exit from Deceleration Fuel Shut Off (DFSO).
EFFECT: control using reliable parameters in a nonaggressive manner.
