FAQ
Q1: What is the function of this NOx sensor?
A1: It measures nitrogen oxide (NOx) concentration in exhaust gases and sends 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 upstream or downstream of the SCR catalyst depending on engine setup.

Q3: What are symptoms of failure?
A3: Engine warning light, SCR system fault codes, increased emissions, poor fuel efficiency, and possible engine derating.

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