The information Mr Loney has provided is correct. Here is the technical description of the particulate matter sensor. Part# FC3Z-5L239-A
The PM11 sensor detects the presence of particulates in the filtered exhaust gas. The sensor element consists of comb electrodes of infinite resistance through which exhaust gases pass. Diesel particulates (soot) are primarily carbon and are a good conductor of electricity. When the particulates pass through the electrodes, they allow voltage to pass from one electrode to another, completing a circuit. This change in resistance is detected by the PM11 module and interpreted as soot leakage.
The PM11 sensor also contains a heater element to regenerate the sensor electrodes. The PM11 module activates the heater element, which heats the sensor to greater than 600°C (1112°F) to burn off soot deposits.
The PM11 sensor is located downstream of the diesel particulate filter. The sensor and module do in fact look like a NOx sensor and module so it is easy to see the reason for confusion.

Back years ago....work at the Electronic Warfare Range in Fallon Nevada.......
I was shop supervisor for multi radar systems and surface to air missle site.....Some of the gear used 400 Hz 120vac power instead of 60 Hz 120vac power. On the work bench we had a 400 Hz outlet. I day I was in real early and started the coffee......Yep, plugged it into the 400 Hz outlet. Damn that coffee brewed Fast and Hot.........
