Abstract
In a control device for a particulate matter detection sensor, a voltage value acquiring unit acquires a sensor voltage value which is a value of a voltage being applied across a pair of electrodes in the particulate matter detection sensor. A current value acquiring unit acquires a sensor current value which is a value of a current flowing between the electrodes. An output unit outputs a PM current value corresponding to the amount of deposit of particulate matter on an element part of the particulate matter detection sensor. States which the particulate matter detection sensor is determined to be in by a state determining unit include a sensor failure state and a PM-deposited state. The state determining unit determines whether the particulate matter detection sensor is in the sensor failure state or the PM-deposited state based on the sensor voltage value and the sensor current value.
