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 reduce emissions.

Q2: Where is it installed?
A2: It is installed in the SCR exhaust aftertreatment system, typically before or after the 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 this compatible with Freightliner trucks?
A4: Yes, it is commonly used in Freightliner vehicles equipped with Mercedes-Benz diesel engines and SCR emission systems.
