This is the pressure sensor for the Diesel Particulate Filter (DPF) system on a Nissan Navara D23 NP300. It is located in the engine bay and connects via hoses to the DPF assembly. This sensor's job is to measure the backpressure in the exhaust, telling the vehicle's computer how full of soot the DPF is. A failed or faulty sensor will send incorrect information, which can cause serious problems. If your vehicle isn't performing DPF burn-offs correctly, or if you have a persistent DPF warning light, a faulty pressure sensor is a likely cause.
Ignoring a faulty DPF pressure sensor can lead to the DPF becoming completely blocked. This can force the vehicle into limp mode, reduce engine power, and ultimately result in a very expensive replacement of the entire DPF assembly.
