Standard Ignition NOX002 Nitrogen Oxide (NOx) Sensor - Upstream

Standard Ignition NOX002 NOx Sensor

Standard Ignition NOX002 is a direct-fit nitrogen oxide sensor for upstream emission monitoring on select Chevrolet and GMC trucks and vans. It is built for OE-style fit, form, and function, with plug-and-play installation and no additional programming required.

Key Features

• Direct-fit OE replacement for straightforward installation
• Upstream nitrogen oxide (NOx) sensor for emission control systems
• Female connector with square housing
• 6-pin male terminals for the specified application
• Extensively tested and validated for performance and reliability
• Manufactured with complete quality control throughout production

Product Details

This Standard Ignition NOX002 sensor is engineered for vehicles that rely on accurate upstream NOx monitoring to support emission system operation. It is a fit for 2010-2014 Chevrolet Express 2500, upstream; 2010-2014 Chevrolet Express 3500, upstream; 2011-2014 Chevrolet Silverado 2500 HD, upstream; 2011-2014 Chevrolet Silverado 3500 HD, upstream; 2010-2014 GMC Savana 2500, upstream; 2010-2014 GMC Savana 3500, upstream; 2011-2014 GMC Sierra 2500 HD, upstream; and 2011-2014 GMC Sierra 3500 HD, upstream. This part cross-references Dorman - OE Solutions 904-422 for the same application.

What It Helps Address

• Fault codes related to NOx sensor performance
• Emission system warning lights
• Incorrect upstream nitrogen oxide readings
• Driveability issues tied to emission control faults
• Failed inspection results caused by sensor-related emission errors

Installation Notes

Use this sensor only in the upstream position listed for the confirmed applications. The connector is female with a square shape, and the terminal layout is 6-pin male, so verify the harness connection before installation. Because this is a plug-and-play OE replacement, no additional programming is required after installation.

Quality Assurance

Standard Ignition backs this NOx sensor with extensive testing and validation during development and production. As a global manufacturer, the brand maintains quality control throughout the manufacturing process to support consistent fit and function.
