What is this NOx sensor used for

It measures nitrogen oxide levels in diesel exhaust gas and sends data to ECU for SCR AdBlue emission control system

Is this inlet or outlet sensor

It is used in SCR aftertreatment system and typically functions as upstream or downstream NOx monitoring depending on configuration

Are all 68460218AB sensors interchangeable

No FCA NOx sensors are ECU coded and must match exact OE number and calibration version

What system does it work with

SCR Selective Catalytic Reduction system using AdBlue injection for Euro 6 diesel emission compliance

What are common failure symptoms
