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 regulate AdBlue/DEF injection and reduce emissions.

Q2: Where is it installed?
A2: It is installed in the exhaust system, usually before or after 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: Are both sensors (498/499) the same?
A4: They are typically used as upstream/downstream NOx sensors in the SCR system, but placement depends on vehicle setup.
