Outlet / Downstream NOx Sensor Position
22303384 is the post-catalyst outlet NOx sensor for the applicable Volvo and Mack SCR aftertreatment system. The sensor monitors nitrogen oxide levels after the exhaust passes through the SCR catalyst, allowing the engine and aftertreatment control system to evaluate SCR performance and emissions levels.
Do not confuse this sensor with Volvo/Mack 22303390, which is used as the pre-catalyst or inlet NOx sensor on applicable systems. Always verify the original sensor number and sensor position before ordering.
