Q3: Is this inlet or outlet sensor?
A3: It can be configured as either upstream or downstream NOx sensor depending on exhaust layout and SCR system design.

Q4: What does this sensor do?
A4: It measures nitrogen oxide (NOx) levels in exhaust gases and sends data to the ECU, which controls AdBlue injection to reduce emissions and maintain SCR efficiency.
