It measures the pressure difference across the DPF to help the engine control module monitor soot buildup and decide when to start regeneration. When the sensor fails, it can trigger false DPF warning lights, inhibit regeneration, and reduce engine performance. Replacing a faulty sensor restores proper exhaust aftertreatment operation.
