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 mounted in the SCR exhaust aftertreatment system, usually before or after the catalytic converter depending on configuration.

Q3: What are symptoms of failure?
A3: Check engine light, SCR/AdBlue warnings, NOx sensor fault codes, reduced engine performance, or limp mode activation.

Q4: Is 5WK97332A interchangeable across Mercedes trucks?
A4: It may be used across multiple Mercedes SCR systems, but exact compatibility depends on engine model, emissions standard, and ECU calibration.
