This article was co-authored by wikiHow staff writer. One sensor that keeps an Eagle Eye on the condition of the DPF is the Differential Pressure Sensor.How can we test this sensor and how can we be sure that the ECU is processing what it sees? If you want to check the sensor while its still attached to your vehicle, use a multimeter and vacuum pump to test the pressure and voltage readings. You can buy vacuum pumps online or from auto part stores. % The ground and 5-volt reference should be identified first with their respective colored codes while backprobing any other signals that might need servicing. This enables the diesel particulate filter to remove more contaminants from the system and keep your diesel emission system working properly. A diesel particulate filter (DPF) differential pressure sensor measures exhaust backpressure and signals when the power-train control module (PCM) should begin a regeneration process to clear the filter of diesel particulate matter (DPM), or soot. Since the DPS and other parameters give a soot number it could be that you are seeing 44 way sooner than you really should be. Thanks, Mike , but I'm trying to figure a way of rodding and chemicaly cleaning it . This keeps this site running and allows me to keep creating content. Also check for pin-to-pin short circuits.

Never attempted a regen works by resetting the time plug it in and wait about 10 seconds and crank. These diagnostic trouble code refer to the condition of the exhaust gas Otherwise, connect your diagnostic tool and read the fault codes. Sometimes the DPF is misdiagnosed as the problem and replaced only to quickly fail again because the sensor is the actual issue. If I understand it correctly, this value is a discrepancy in the readings between the two sides of the sensor that the ECU learns and compensates for. Always work outdoors or in a well-ventilated space when running your vehicle to prevent harmful fumes from building up. If the soot load is high, a higher pressure difference is observed, because the accumulated soot will provide a restriction to flow on the DPF inlet side (Inlet pressure > Outlet pressure). Without this sensor, the DPF would fill up with diesel particulate matter or soot and the truck would eventually be put into derate and would be restricted to limp mode which can be as little as 5 MPH. stream Exhaust Gas Recirculation (EGR): 1228, 1896, 2272, 2349, 2353, 2357, 2961, 2962, 3136, 3137, 3138, 3342, 3382, 3383, 3389 Simply the best offers on diagnostic tools for the US market.
