The control system of an internal combustion engine controls an internal combustion engine comprising an exhaust sensor. The control system comprises a motoring device driving rotation of a crankshaft of the internal combustion engine, a motoring control part configured to control the motoring device, a heater control part configured to control supply of electric power to the heater, and a temperature estimating part configured to estimate a temperature of the sensor element. The motoring control part is configured to drive the motoring device for a predetermined time when the temperature of the sensor element estimated by the temperature estimating part is outside a predetermined cracked element temperature region while the heater control part is supplying electric power to the heater, and stop driving the motoring device when the temperature of the sensor element is within the cracked element temperature region.
