Standard Ignition NOX046 NOx Sensor

Standard Ignition NOX046 is a nitrogen oxide (NOx) sensor for diesel emission control systems that monitor exhaust aftertreatment performance. It uses a female rectangular connector with 6 male pin terminals for a direct-fit electrical connection on the specified applications.

Key Features

  • Nitrogen oxide (NOx) sensor for emission control system monitoring
  • Female connector with rectangular housing
  • 6-pin male terminal interface
  • Direct replacement for the listed upstream applications
  • Cross-references Standard Ignition NOX046, 24001917, DNX046, DNX1046, and NOX1046 for the same application

Application Details

Compatible with 2020-2022 Chevrolet Express 2500, upstream; 2020-2022 Chevrolet Express 3500, upstream; 2020-2022 GMC Savana 2500, upstream; and 2020-2022 GMC Savana 3500, upstream. This NOx sensor is specified for the upstream position on these Chevrolet Express and GMC Savana diesel applications, where accurate exhaust gas monitoring supports emission system operation.

What It Helps Address

  • Check engine light related to NOx sensor performance
  • Fault codes tied to exhaust aftertreatment monitoring
  • Incorrect nitrogen oxide readings in the emission control system
  • Upstream sensor signal issues on supported Chevrolet Express and GMC Savana models
  • Emission system diagnostics that point to a failed nitrogen oxide sensor

Installation Notes

Verify the upstream sensor location, connector style, and terminal layout before installation. Match the vehicle application to the listed Chevrolet Express 2500, Chevrolet Express 3500, GMC Savana 2500, or GMC Savana 3500 fitment, and confirm the part number NOX046 against the original sensor before replacement.

Quality Assurance

Standard Ignition supplies emission control components for service replacement applications. NOX046 is built to match the listed connector and terminal configuration for the specified vehicle fitment.
