It measures soot concentration after the diesel particulate filter to monitor filter efficiency and support regeneration control.\u003c\/p\u003e\n\u003cp\u003eFunction: Installed downstream of the DPF in the exhaust aftertreatment system, the sensor continuously measures particulate emissions and sends data to the ECU. This helps optimize regeneration cycles, detect DPF inefficiency, and ensure emissions compliance.\u003c\/p\u003e","brand":"ASHENG","offers":[{"title":"Default Title","offer_id":51636240187524,"sku":"LK21-5L216-AA","price":210.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0966\/8313\/1012\/files\/12_bc313902-d4ef-4476-86bc-d51a8c802e82.jpg?v=1773731910","url":"https:\/\/www.jslook.com\/products\/pm-sensor-lk21-5l216-aa-0281008055-diesel-dpf-sensor","provider":"ASHENG","version":"1.0","type":"link"}
