This Global Parts NOx sensor is a specific-fit emission control sensor for the SCR catalyst outlet on select Ram heavy-duty trucks. Built with a 4-terminal blade connection and an oblong female connector, it supports direct replacement needs for 2014-2017 Ram 2500 and 2015-2017 Ram 3500 applications.

Key Features

• Specific-fit Nitrogen Oxide (NOx) sensor for emission control service
• Blade terminal type with 4 terminals
• Oblong connector shape with female connector gender and male terminal gender
• Fits the SCR catalyst outlet position
• Cross-reference part number: Standard Ignition NOX012
• Part number 1815159 for catalog and search identification

Detailed Description

Global Parts 1815159 is a gpd NOx Sensor made for emission control systems that monitor nitrogen oxide levels in the exhaust stream. This sensor is a specific-fit replacement for Ram 2500 and Ram 3500 diesel applications at the SCR catalyst outlet, where accurate exhaust aftertreatment feedback is needed for proper system operation. The 4-blade terminal layout and oblong connector help match the original-style electrical interface for service replacement.

Fits 2014-2017 Ram 2500, SCR Catalyst Outlet. Fits 2015-2017 Ram 3500, SCR Catalyst Outlet. This part cross-references Standard Ignition NOX012 for the same application. Search terms such as Ram 2500 NOx sensor replacement, Ram 3500 SCR catalyst outlet sensor, and Global Parts 1815159 are commonly used for this fitment.

What It Helps Address

• NOx sensor fault codes related to exhaust aftertreatment monitoring
• SCR system communication issues at the catalyst outlet
• Emission control warning lights tied to sensor signal problems
• Incorrect nitrogen oxide readings affecting diesel exhaust treatment performance
• Replacement needs for damaged connector or terminal interfaces

Installation Notes and Tips

Verify the connector shape, terminal count, and SCR catalyst outlet location before installation. Confirm the vehicle year, make, and model against the listed fitment for 2014-2017 Ram 2500 and 2015-2017 Ram 3500. Inspect the harness connector and surrounding exhaust components for heat damage or corrosion before connecting the new sensor. Use the vehicle service procedure for proper sensor removal and installation.

Quality Assurance

Global Parts supplies this NOx sensor as a specific-fit emission control replacement for the listed Ram applications. Part number 1815159 is cataloged for direct identification and fitment matching.
