Standard Ignition DPS122 diesel particulate filter (DPF) pressure sensor for the 2019-2023 Ram 2500 6-cylinder 6.7L and other vehicles senses exhaust pressure at the filter for the engine computer. The computer uses that reading to track how clogged the filter is.
A particulate filter warning light or reduced engine power can mean the sensor has failed. These signs alone do not prove the sensor is the problem, since a clogged filter is another common cause.
The 2019-2023 Ram 2500 6-cylinder 6.7L, the 2019-2023 Ram 3500 6-cylinder 6.7L and the 2019-2023 Ram 5500 6-cylinder 6.7L all take this direct-fit OE replacement sensor, which is made for ease of installation, and so do other vehicles. Each one takes a single sensor. If your vehicle is not one of these, look up its year and engine in the "Vehicles it fits" section.
