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 dosing and maintain emissions compliance.

Q2: Where is it installed?
A2: It is installed in the exhaust system, typically upstream or downstream of the SCR catalytic converter depending on vehicle 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 universal?
A4: It is widely used across many OEMs, but exact compatibility depends on engine model and SCR system setup.
