FITMENT
Compatible with GM diesel trucks equipped with SCR (Selective Catalytic Reduction) AdBlue emission systems requiring NOx monitoring.
Common applications include:

  • GMC Sierra 2500HD / 3500HD (2017–2019 diesel variants)
  • Chevrolet Silverado 2500HD / 3500HD (2017–2019 diesel variants)
    Using reference: 12680215 (Duramax SCR emission systems).

FAQ
Q1: What is the function of this NOx sensor?
A1: It measures nitrogen oxide (NOx) levels in the exhaust system and sends data to the ECU to control AdBlue/DEF injection and ensure emissions compliance.

Q2: Where is it installed?
A2: It is mounted on the exhaust system, typically before or after the SCR catalytic converter depending on configuration.

Q3: What are symptoms of failure?
A3: Check engine light, SCR/AdBlue system warnings, NOx sensor fault codes, reduced engine performance, or limp mode activation.

Q4: Is it compatible with all Sierra / Silverado models?
A4: No, compatibility depends on engine type (Duramax diesel variants), model year, and SCR system setup.
