Standard Ignition NOX047 Nitrogen Oxide (NOx) Sensor - Downstream

Standard Ignition NOX047 NOx Sensor Overview

The Standard Ignition NOX047 is a nitrogen oxide sensor for downstream emission monitoring on select Chevrolet and GMC applications. It uses a female rectangular connector with 6 male pin terminals for a direct-fit electrical interface on supported vehicles.

Key Features

• Nitrogen oxide (NOx) sensor for downstream exhaust monitoring
• Female connector with 1 rectangular connector housing
• 6-pin male terminal design
• Direct replacement part for emission control service
• Cross-references Standard Ignition NOX047 applications with OE-style interchange numbers

Detailed Description

Standard Ignition NOX047 is built for downstream NOx sensor service on 2020-2022 Chevrolet Colorado, Chevrolet Express 2500, Chevrolet Express 3500, GMC Canyon, GMC Savana 2500, and GMC Savana 3500 applications. This part number, NOX047, is also referenced by interchange numbers 24001918 and DNX047 for the same application family. The connector layout and 6-pin terminal configuration support proper electrical connection in emission control systems that monitor exhaust aftertreatment performance.

What It Helps Address

• Check engine lights related to NOx sensor faults
• Emission system diagnostic trouble codes
• Incorrect downstream nitrogen oxide readings
• Aftertreatment monitoring issues on supported Chevrolet and GMC models
• Failed emissions inspection results tied to sensor malfunction

Installation Notes and Tips

Verify the connector shape, terminal count, and downstream position before installation. Confirm the vehicle year, make, and model against the fitment list for NOX047, especially on Chevrolet Colorado and GMC Canyon applications. Inspect the harness and exhaust-side connector for heat damage or corrosion before replacing the sensor.

Quality Assurance

Standard Ignition supplies emission control components for service replacement use. This NOx sensor is identified by part number NOX047 and supported by listed interchange references for application matching.
