Description
Product Overview
Part Name: Downstream Nitrogen Oxide Sensor (NOx)
Part Number: 22827993
Vehicle Compatibility: Volvo FH13, FH16, FM9, FM11, FM13 & FMX Trucks (2013–2024) equipped with Euro-emission SCR aftertreatment systems that require downstream NOx sensor reference 22827993. Positioned after the SCR catalyst to monitor post-treatment NOx levels for full emissions compliance.
Configuration: OE-style downstream NOx sensor featuring a ceramic sensing element, stainless-steel probe and high-temperature wiring harness with sealed connector. Designed for long-term durability in high-heat exhaust environments.
Function: Measures NOx concentration after the SCR catalyst to verify DEF dosing effectiveness, maintain emissions performance, prevent derate conditions and support accurate ECU diagnostics.
Technical Specifications
Type: Downstream (post-SCR) NOx Sensor
