Manufactured by Skyline to strict Original Equipment (OE) standards, this upstream Nitrogen Oxide sensor continuously monitors the raw exhaust gases leaving your engine before they enter the SCR system. A fouled inlet NOx sensor will trigger the check engine light, cause poor fuel economy, and eventually force your truck into a severe Limp Mode derate. We stock these heavily right here in our Hanover Park, Illinois warehouse to ensure lightning-fast shipping for fleets, diesel shops, and owner-operators nationwide.\u003c\/p\u003e\n\n\u003ch2\u003eClear DEF Codes: The Detroit Diesel Inlet NOx Sensor Advantage\u003c\/h2\u003e\n\n\u003cp\u003eThis \u003cstrong\u003eDetroit Diesel Inlet NOx Sensor\u003c\/strong\u003e is engineered to deliver highly accurate, real-time emissions baseline data directly to your engine control unit (ECU). Mounted upstream (at the inlet) of the SCR catalyst, it allows the ECU to calculate the precise amount of Diesel Exhaust Fluid (DEF) required to neutralize harmful nitrogen oxide gases. Built to withstand brutal pre-treatment exhaust temperatures, extreme vibration, and heavy soot buildup, this Skyline sensor guarantees OE-level response times and unmatched durability.\u003c\/p\u003e\n\n\u003cp\u003eAs we continue to build the largest inventory of commercial truck parts in Illinois, we prioritize aftertreatment electronics that eliminate diagnostic headaches and rework. Serving as a direct exact-fit replacement for heavily searched Detroit Diesel OEM numbers like A0121536328 and A0111536128, this sensor plugs directly into your factory wiring harness without complex splicing. Upgrade your emissions system today with a reliable, guaranteed-to-fit sensor that keeps your truck out of the shop and out on the road.\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eVehicle Fitment \u0026amp; Compatibility\u003c\/h3\u003e\n\u003cp\u003eThis OE-quality Skyline nitrogen oxide sensor is precision-engineered for the following heavy-duty exhaust applications:\u003c\/p\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eEngine Make:\u003c\/strong\u003e Detroit Diesel\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eExhaust Position:\u003c\/strong\u003e Inlet \/ Upstream (Pre-SCR Catalyst)\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eComponent Function:\u003c\/strong\u003e Baseline Nitrogen Oxide (NOx) Emissions Monitoring\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eDirect Replacement \u0026amp; Cross-Reference Numbers:\u003c\/h3\u003e\n\u003cp\u003e\u003cem\u003eThis upstream NOx sensor serves as a direct exact-fit replacement for the following part numbers:\u003c\/em\u003e\u003c\/p\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSkyline:\u003c\/strong\u003e SNX114\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDetroit Diesel OEM:\u003c\/strong\u003e A0121536328, EA0121536328, RA0121536328, A0111536128, EA0111536128, RA0111536128\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAftermarket Interchange:\u003c\/strong\u003e 3FL022\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSensor Type:\u003c\/strong\u003e Nitrogen Oxide (NOx) Sensor\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMounting Location:\u003c\/strong\u003e Inlet (Upstream)\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eProduct Level:\u003c\/strong\u003e OE Manufactured\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Skyline (Distributed by FleetPro Parts \u0026amp; Tires)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Skyline","offers":[{"title":"Default Title","offer_id":42620482879559,"sku":"FSNX114","price":371.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0587\/8035\/2583\/files\/fsnx114-detroit-diesel-inlet-nox-sensor-skyline-snx114-oe-a0121536328-skyline-5277727.jpg?v=1779136522","url":"https:\/\/fleetpropt.com\/products\/detroit-diesel-inlet-nox-sensor-skyline-snx114-oe-a0121536328","provider":"FLEETPRO PARTS \u0026 TIRES ","version":"1.0","type":"link"}
