Built as an OE replacement, it is shaped for proper fit, form, and function and uses a plug-and-play design with no additional programming required.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eDirect-fit NOx sensor for downstream placement\u003c\/li\u003e\n\u003cli\u003eOE-style replacement for clean installation and correct sensor location\u003c\/li\u003e\n\u003cli\u003ePlug-and-play design with no extra programming required\u003c\/li\u003e\n\u003cli\u003eFemale connector with oval shape\u003c\/li\u003e\n\u003cli\u003e6 male blade terminals for vehicle-specific connection\u003c\/li\u003e\n\u003cli\u003eExtensively tested and validated for performance and reliability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eDetailed Description\u003c\/h2\u003e\u003cp\u003eStandard Ignition NOX005 is engineered for diesel emission control systems that rely on accurate nitrogen oxide measurement after the aftertreatment system. It is a practical replacement for a failed downstream NOx sensor on 2017-2018 Chevrolet Silverado 2500 HD and Silverado 3500 HD, as well as 2017-2018 GMC Sierra 2500 HD and Sierra 3500 HD. The connector design, terminal layout, and OE-style construction support a straightforward repair when the original sensor has triggered emissions faults or drivability concerns.\u003c\/p\u003e\u003cp\u003eThis part cross-references ACDelco-style applications such as 12673517 and 12676706 for the same vehicle coverage. Standard Ignition NOX005 is also a useful search match for drivers looking for a downstream NOx sensor for 2017-2018 Silverado 2500 HD, Silverado 3500 HD, Sierra 2500 HD, or Sierra 3500 HD diesel models.\u003c\/p\u003e\u003ch2\u003eCommon Issues This Part Can Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCheck engine light related to NOx sensor performance\u003c\/li\u003e\n\u003cli\u003eEmissions system fault codes tied to downstream nitrogen oxide readings\u003c\/li\u003e\n\u003cli\u003eIncorrect exhaust aftertreatment monitoring data\u003c\/li\u003e\n\u003cli\u003eFailed sensor response in diesel emissions control diagnostics\u003c\/li\u003e\n\u003cli\u003eReplacement needs after connector or sensor wear\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eVerify the downstream sensor location before installation and match the connector style, terminal count, and position to the original part. Standard Ignition NOX005 is a plug-and-play replacement, so no additional programming is required after installation. For best results, inspect the harness and connector for heat damage, corrosion, or bent terminals before connecting the new sensor.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eStandard Ignition states that this sensor undergoes extensive testing and validation to support proper performance and reliable operation. As a global manufacturer, the company maintains quality control throughout the production process to help ensure consistent OE-style replacement quality.\u003c\/p\u003e","brand":"Standard Ignition","offers":[{"title":"Default Title","offer_id":52820731494581,"sku":"FBHK-NOX005","price":231.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/1442\/1173\/files\/SI_NOX005_Fro.jpg?v=1784524981","url":"https:\/\/www.partcatalog.com\/products\/standard-ignition-nox005-nitrogen-oxide-nox-sensor-downstream","provider":"PartCatalog","version":"1.0","type":"link"}
