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. When this sensor is not working properly it compromises the regeneration process and will eventually lead to diesel emissions system failure. The ground and 5-volt reference should be identified first with their respective colored codes while backprobing any other signals that might need servicing. Noticed exhaust temp upstream of dpf was 650-750, then dropped to 350 after. It's important to rev the engine and check for voltage changes before testing anything else.

Assuming that you validated your repair after each step that youpreviously followed (run engine, test drive etc): If fault code 1922 is still active OR inactive with more than one counts in the last 25 operating hours, the DPF is fully clogged. Soot load is estimated by the ECM, by monitoring the inlet and outlet pressure of the filter. The whole system must work in close-knit harmony to deliver a reliable drive, time and again. Active and stationary regeneration of the DPF will be disabled. If we can find it, we should be able to cut post inject to next to nothing where as when the regen is initiated there is actually nothing happening externally but you are telling the ECM that is is happening and it's happy. Important to note: The vehicle or machine manufacturer is responsible to construct the wiring harness and allow the sensor to eventually connect to the ECM. i replaced the dpf with a cummins reman. .
