Global Parts 1815158 Nitrogen Oxide (NOx) Sensor - Turbocharger Outlet Pipe

NOx Sensor for Emission Control

Global Parts 1815158 is a nitrogen oxide (NOx) sensor for emission control systems that monitor exhaust aftertreatment performance. It uses a rectangular female connector with 4 blade terminals and male terminal ends for a direct electrical interface in the vehicle harness.

Built for diesel emission monitoring, this NOx sensor supports accurate exhaust gas measurement in applications that require precise sensor feedback. If you are replacing a failing NOx sensor on a Freightliner, International, or Cummins-powered vehicle, part number 1815158 is a direct-reference option to verify against your original unit.

Key Features

• Nitrogen oxide (NOx) sensor for emission control service
• Rectangular connector shape for OE-style fitment
• Female connector gender with male terminal gender
• 4 blade terminals for electrical connection
• Global Parts part number 1815158

Detailed Description

Global Parts 1815158 is a gpd NOx Sensor designed around the connector and terminal configuration commonly used in diesel exhaust aftertreatment systems. The rectangular 4-terminal layout helps ensure the replacement matches the original sensor connection style, which is important when servicing NOx monitoring circuits on heavy-duty vehicles. This part cross-references 2872948 and 5295473 for the same application.

When sourcing a replacement NOx sensor for Freightliner, International, or Cummins applications, confirm the connector shape, terminal count, and terminal gender against the original part before installation. Part number 1815158 is intended for emission control repairs where accurate NOx signal input is required by the vehicle’s control system.

What It Helps Address

• NOx sensor fault codes
• Diesel exhaust aftertreatment warning lights
• Incorrect exhaust emissions readings
• Reduced emission system performance
• Failed sensor communication in the harness connection

Installation Notes and Tips

Before installation, compare the original sensor connector, terminal count, and terminal gender to the replacement unit. Inspect the harness connector for corrosion, heat damage, or bent terminals, and clear any stored diagnostic trouble codes after the repair is complete. For best results, verify application details by VIN or original part number when servicing Freightliner, International, or Cummins diesel emission systems.

Quality Assurance

Global Parts supplies emission control components built to match the specified connector and terminal configuration for replacement use. Always confirm fitment details against the original sensor and vehicle service information before installation.
