    摘要： A detection apparatus is used to detect a failure of a particulate filter. The detection apparatus includes a PM (particulate matter) sensor, a timing estimating unit, and a failure determining unit. The PM sensor is disposed at a downstream side of the particulate filter in an exhaust passage. The PM sensor includes a pair of electrodes and detects an amount of the PM based on current passing through the PM deposited between the electrodes. The estimating unit estimates a failure-state energization timing at which the PM sensor starts to be energized due to the PM deposited between the electrodes assuming that the particulate filter has failed. The determining unit determines that the particulate filter is in a failure state when an actual energization timing of the PM sensor based on an output of the PM sensor is earlier than the failure-state energization timing estimated.
