Standard Ignition NOX005 Nitrogen Oxide (NOx) Sensor - Downstream

OE Replacement NOx Sensor for GM Diesel Applications

Standard Ignition NOX005 is a direct-fit nitrogen oxide sensor for downstream emissions monitoring on select Chevrolet Silverado 2500 HD and Silverado 3500 HD, plus GMC Sierra 2500 HD and Sierra 3500 HD models. 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.

Key Features

• Direct-fit NOx sensor for downstream placement
• OE-style replacement for clean installation and correct sensor location
• Plug-and-play design with no extra programming required
• Female connector with oval shape
• 6 male blade terminals for vehicle-specific connection
• Extensively tested and validated for performance and reliability

Detailed Description

Standard 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.

This 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.

Common Issues This Part Can Address

• Check engine light related to NOx sensor performance
• Emissions system fault codes tied to downstream nitrogen oxide readings
• Incorrect exhaust aftertreatment monitoring data
• Failed sensor response in diesel emissions control diagnostics
• Replacement needs after connector or sensor wear

Installation Notes and Tips

Verify 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.

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 to help ensure consistent OE-style replacement quality.
