Abstract

An oxidation catalyst (OC)/hydrocarbon injector (HCI) testing system includes a controller having a first oxygen sensor input configured and disposed to receive a first oxygen sensor value upstream of an oxidation catalyst (OC) device and a second oxygen sensor input configured to receive a second oxygen sensor value downstream of the OC device. The controller is configured and disposed to perform a first test to detect one of a faulty OC device and a faulty HCI based on a difference between the first and second oxygen sensor values.
