Standard Ignition NOX052 Nitrogen Oxide (NOx) Sensor - Downstream

Standard Ignition NOX052 Nitrogen Oxide Sensor

Standard Ignition NOX052 is a nitrogen oxide sensor for emission control systems that monitor exhaust NOx levels. It uses a rectangular female connector with 6 male pin terminals, making it a direct-fit style electrical component for vehicles that require this connector layout.

Key Features

• Nitrogen oxide (NOx) sensor for emission control diagnostics
• Rectangular 1-connector design with female connector gender
• 6-pin male terminal configuration
• Standard Ignition NOX052 part number for catalog matching
• Cross-reference part numbers include 12708008 and DNX052 for the same application

Detailed Description

Standard Ignition NOX052 is built for exhaust aftertreatment and emissions monitoring systems that rely on accurate NOx feedback. In vehicles such as Mercedes-Benz and BMW applications that use this sensor style, the NOx sensor helps the engine control system track exhaust composition and maintain proper emissions strategy. The NOX052 part number is useful when replacing a failed sensor or matching an existing OE-style connector configuration.

This sensor’s rectangular connector housing, female connector interface, and 6-pin male terminal layout are important details for confirming electrical compatibility before ordering. When searching for a nitrogen oxide sensor for Mercedes-Benz or BMW diesel emission control service, NOX052 is a relevant reference point for the correct connector and terminal style.

What It Is Used For

• Replacing a failed NOx sensor that triggers emissions-related fault codes
• Restoring exhaust gas monitoring in diesel emission control systems
• Addressing inaccurate nitrogen oxide readings from a worn sensor
• Correcting connector mismatch issues during sensor replacement
• Supporting proper engine management and emissions diagnostics

Installation Notes and Tips

Verify the connector shape, terminal count, and connector gender against the original sensor before installation. Confirm the vehicle’s OE part number and harness style, especially on Mercedes-Benz and BMW diesel applications, to ensure the NOX052 matches the existing electrical connection. Inspect the harness and exhaust-side mounting area for heat damage, corrosion, or soot buildup before installing the replacement sensor.

Quality Assurance

Standard Ignition is a recognized aftermarket brand for electrical and emissions-related components. This part cross-references 12708008 and DNX052 for the same application.
