OE-Style NOx Sensor for Downstream Emissions Control
The Standard Ignition NOX003 is a direct-fit nitrogen oxide sensor built for downstream emissions monitoring on select 2015 Chevrolet and GMC heavy-duty applications. Its plug-and-play design helps simplify replacement while maintaining the proper fit, form, and function expected from an OE-style sensor.
- Direct-fit OE replacement for straightforward installation
- Plug-and-play design with no additional programming required
- Downstream NOx sensor for emissions system monitoring
- Female connector with square housing
- 6-pin male terminals for the specified application
- Extensively tested for performance and reliability
Fitment Details
Compatible with 2015 Chevrolet Express 2500, downstream; 2015 Chevrolet Express 3500, downstream; 2015 Chevrolet Silverado 2500 HD, downstream; 2015 Chevrolet Silverado 3500 HD, downstream; 2015 GMC Savana 2500, downstream; 2015 GMC Savana 3500, downstream; 2015 GMC Sierra 2500 HD, downstream; and 2015 GMC Sierra 3500 HD, downstream.
Standard Ignition NOX003 is engineered as an OE replacement nitrogen oxide sensor for downstream placement, making it a practical choice for restoring emissions-system feedback on Chevrolet Silverado 2500 HD, Silverado 3500 HD, Express vans, and GMC Sierra and Savana heavy-duty models. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
What It Helps Address
- Fault codes related to downstream NOx sensor performance
- Incorrect nitrogen oxide readings in the emissions system
- Emissions monitoring issues on diesel-equipped heavy-duty vehicles
- Driveability concerns caused by sensor signal problems
- Replacement needs for a worn or failed OE-style NOx sensor
Installation Notes
Verify connector shape, terminal count, and downstream placement before installation. The NOX003 uses a female connector, square housing, and 6-pin male terminals, so matching the original sensor configuration is important for proper fitment on the intended Chevrolet and GMC applications. Because it is a plug-and-play replacement, no additional programming is required after installation.
Quality Assurance
Standard 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.
