Abstract: After an engine is started, an ECU performs first regeneration processing of a PM sensor through heating by a heater and, after the first regeneration processing, applies a voltage continuously to detection electrodes for a predetermined voltage application period. The ECU causes PM to adhere to an insulating substrate due to the voltage application and, at a time point after the predetermined time period has elapsed, determines the amount of PM that is adhering to the insulating substrate. When a predetermined condition is satisfied outside the voltage application period, the ECU determines whether the amount of adhering PM on the insulating substrate is equal to or greater than an excess determination threshold value. If the amount of adhering PM is determined to be equal to or greater than the excess determination threshold value, the ECU performs second regeneration processing of the PM sensor, through heating by the heater.
