Detailed Description

This Global Parts gpd NOx Sensor is built for emission control systems that measure nitrogen oxide levels in the exhaust stream and send data to the vehicle’s control modules. The specific-fit design, 12-volt rating, and 4-terminal blade connection help match the original sensor interface used in targeted Dodge Ram and Ram diesel applications. If you are replacing a failed NOx sensor on a Ram 2500 or Ram 3500, or servicing a Dodge Ram emissions fault, part number 1815139 provides the correct sensor format for the listed application.

What It Helps Address

  • Check engine light related to NOx sensor performance
  • Emission system fault codes tied to exhaust gas monitoring
  • Incorrect nitrogen oxide readings reported to the ECU
  • Aftertreatment system issues caused by sensor signal loss
  • Driveability concerns linked to emissions system faults on Dodge Ram and Ram diesel models

Installation Notes and Tips

Verify connector shape, terminal count, and voltage before installation to confirm the replacement matches the original sensor. Inspect the harness and connector for heat damage, corrosion, or bent terminals before connecting the new sensor. Clear stored diagnostic trouble codes after installation and confirm the emissions system completes its relearn or readiness checks as required by the vehicle.

Quality Assurance

Global Parts supplies this NOx sensor as a specific-fit emission control replacement built to match the listed electrical and connector specifications for the application.
