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

Q2: Where is it installed?
A2: It is installed in the exhaust system, typically before or after the SCR catalyst depending on engine setup.

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

Q4: Is it compatible with all Cummins engines?
A4: No, compatibility depends on engine model, emissions standard, and SCR system configuration.
