摘要： A particulate matter detecting apparatus that measures an amount of particulate matter in a gas by applying a predetermined voltage between a pair of first electrodes of a sensor element portion includes a detecting portion that detects whether more particulate matter than a reference amount has accumulated on the first electrodes, a temperature controlling portion that controls a temperature of the sensor element portion to become equal to or higher than a reference temperature when it is detected that more particulate matter than the reference amount has accumulated, and a voltage controlling portion that applies a reference voltage between the first electrodes and a second electrode arranged such that a solid electrolyte is sandwiched between the second electrode and the first electrodes, when it is detected that more particulate matter than the reference amount has accumulated.

摘要： An oxygen concentration sensor (28) is disposed in an engine exhaust passageway. The alcohol concentration in the fuel used in the internal combustion engine is detected. A target impedance is set on the basis of the detected alcohol concentration. The actual impedance of a sensor element of the oxygen concentration sensor (28) is detected. The heater output of the exhaust gas sensor is controlled so that the actual impedance becomes equal to the target impedance, whereby the temperature of the sensor element represented by the impedance becomes equal to a target temperature represented by the target impedance.
