NOx Sensor Module for Transit Diesel Applications

Standard Ignition NOX037 is a nitrogen oxide sensor module for diesel emission control systems. It is built with a female 2-connector layout, male blade terminals, and 8; 5 terminal positions for direct replacement service on supported Ford Transit vans.

Key Features

  • Nitrogen Oxide (NOx) sensor module for emission control diagnostics
  • Female connector gender with 2 connectors
  • Male blade terminals with 8; 5 terminal quantity
  • Direct-fit replacement for Ford Transit-150, Transit-250, Transit-350, and Transit-350 HD
  • Cross-reference part number: DC3Z5K202B
  • Standard Ignition part number NOX037 for service identification

Detailed Description

Standard Ignition NOX037 is a replacement NOx sensor module used in diesel emission control systems to monitor nitrogen oxide levels and support engine management and aftertreatment operation. This part is listed for 2015-2019 Ford Transit-150, 2015-2019 Ford Transit-250, 2015-2019 Ford Transit-350, and 2015-2019 Ford Transit-350 HD. It cross-references DC3Z5K202B for the same application. The connector and terminal configuration should be matched carefully during service to ensure proper electrical connection and sensor communication.

What It Is Used For

  • Replacing a failed NOx sensor module on Ford Transit diesel applications
  • Addressing emission system fault codes related to nitrogen oxide monitoring
  • Restoring accurate exhaust aftertreatment sensor input
  • Correcting drivability issues triggered by emission control sensor faults
  • Supporting inspection and emissions-related repair needs

Installation Notes and Tips

Verify connector gender, connector count, and terminal layout before installation. Confirm the vehicle application against the listed fitment for 2015-2019 Ford Transit-150, Transit-250, Transit-350, and Transit-350 HD. Inspect the harness and connector terminals for corrosion, bent blades, or heat damage before connecting the new module. Clear diagnostic trouble codes and confirm system operation after installation.
