exhaust gas concentration in order to burn off the trapped particles (oxidizing the
particles to form CO2 and water). The computer monitors the efficiency of the
filter in trapping particulate matter, as well as the ability of the filter to regenerate
(self-clean).
The PM Filter Monitor is supported by "compression ignition" vehicles only. The
PM Filter Monitor is a "Two-Trip" Monitor. If a fault is found on the first trip, the
computer temporarily saves the fault in its memory as a Pending Code. The
computer does not command the MIL on at this time. If the fault is sensed again
on the second trip, the computer commands the MIL "On," and saves the code in
its long-term memory.
