Abstract: An apparatus which detects particulate matter is provided. This apparatus estimates a volume of water inside an exhaust passage using estimation sections. When an estimated volume of water is larger than a water drainage threshold, an element portion is heated using a heater by the first temperature range controller, in a temperature range which resists water-induced cracking independent of a volume of water droplets. If the estimated volume of water is less than a water drainage threshold, the water drainage determination section determines that the water drainage of the exhaust passage is completed. Additionally, if it is estimated that the water drainage is completed, the element portion is heated by a second temperature controller at temperature lower than a starting temperature of combustion of particulate matter and in order to repel water adhered onto the element portion in a water-repellent temperature range for a predetermined period.

The sensor cell works to measure an oxygen ion current flowing between a sensor electrode and a reference electrode. The gas sensor device is designed to subtract the oxygen ion current value I2, as measured by the sensor cell a given period of time after spraying of fuel into the internal combustion engine is interrupted, from the oxygen ion current value I1, as measured by the sensor cell when the fuel is being sprayed into the internal combustion engine, to derive the concentration of a given gas component based on the corrected oxygen ion current value I.
