Genuine OEM DPS Sensor. Often referred to as "Particle Matter Sensor"
The diesel particulate sensor consists of a measuring probe and evaluation electronics.
Deposited soot particulates form electrical paths between electrodes on which a current flows. This signal is evaluated by the evaluation electronics. From this, the evaluation electronics determines the functional capability of the diesel particulate filter to store particulates.
The evaluation electronics forwards these signals to the Digital Diesel Electronics (DDE).
If the diesel particulate sensor fails, the following behaviour can be expected:
