FIELD: engines and pumps.
SUBSTANCE: provides a method for controlling exhaust gases sensor, installed in the exhaust system of the engine. The method consists in that, the operation of the engine is controlled in response to the deterioration of exhaust gases sensor characteristics, the deterioration is identified during the deceleration fuel shut off (DFSO), and compensated on the basis of whether fuel vapor blowing occurs during the deceleration fuel shut off.
EFFECT: increase of combustion process efficiency.
