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 exhaust system, usually before or after the SCR catalytic converter depending on engine 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 SNS0961 the same as 55589456?
A4: Yes, SNS0961 is a sensor model reference, while 55589456 is the OEM number and 5WK97418 is the Continental part reference used for the same system.
