Standard Ignition NOX073 Nitrogen Oxide (NOx) Sensor - Tail Pipe, Turbocharger Outlet Pipe or Upstream

Standard Ignition NOX073 NOx Sensor Overview

Standard Ignition NOX073 is a nitrogen oxide sensor for emission control systems that monitor exhaust NOx levels. It uses a screw-in mounting style with a 4-terminal blade connector and male terminals for a direct electrical interface in the correct application.

Compatible With select emission control applications, this NOx sensor supports accurate exhaust gas monitoring for vehicles such as Ford F-150 and Ford Super Duty diesel models where NOx feedback is part of the aftertreatment system. The NOX073 part number is also referenced as a service replacement under related interchange numbers.

Key Features

• Nitrogen oxide (NOx) sensor for emission control system monitoring
• Screw-in mounting type for threaded exhaust installation points
• 4-terminal blade connector with male terminals
• Standard Ignition NOX073 for service and repair use
• Cross-reference part number: 3687930

Detailed Description

Standard Ignition NOX073 is built for vehicles that rely on NOx sensing to manage exhaust aftertreatment performance and emissions feedback. The screw-in design installs at the sensor port in the exhaust stream, while the 4-blade terminal layout supports the electrical connection required by the vehicle system. When replacing a failed NOx sensor, matching the connector style and mounting type is critical for proper communication with the control module. This part number, NOX073, is commonly searched for Ford F-150 and Ford Super Duty diesel emission repair applications.

Common Issues This Part Addresses

• Check engine light related to NOx sensor circuit faults
• Incorrect exhaust emissions readings from a failing sensor
• Aftertreatment system faults tied to NOx monitoring
• Communication errors caused by damaged sensor terminals or connector mismatch
• Emission control performance issues in diesel exhaust systems

Installation Notes and Tips

Verify the connector style, terminal count, and screw-in mounting location before installation. Inspect the exhaust port threads and wiring harness condition, and confirm the replacement sensor matches the original application by part number and vehicle configuration. For best results, clear diagnostic trouble codes after installation and verify system operation with a scan tool.

Quality Assurance

Standard Ignition is a recognized aftermarket brand for electrical and emission control components. NOX073 is built to match the specified mounting and terminal configuration for the intended application.
