Description
Product Overview
Part Name: Upstream Nitrogen Oxide Sensor (NOx)
Part Number: 22827991
Vehicle Compatibility: Volvo FH13, FH16, FM9, FM11, FM13 & FMX Trucks (2013–2024) equipped with Euro-emission SCR systems that require upstream NOx sensor reference 22827991. Installed before the SCR catalyst to monitor engine-out NOx levels across long-haul, regional and construction-duty Volvo platforms.
Configuration: OE-spec upstream NOx sensor featuring a heat-resistant ceramic sensing element, stainless-steel probe, and a durable wiring harness with sealed connector designed for high-temperature exhaust environments.
Function: Measures engine-out NOx concentration to help the ECU regulate combustion parameters, fuel injection, EGR activity and initial DEF dosing strategy. Supports emissions compliance, efficient aftertreatment performance and prevents derate or fault-code conditions.
Technical Specifications
Type: Upstream (pre-SCR) NOx Sensor
Material: Stainless-steel probe, ceramic sensing core and thermally protected wiring assembly
Application: Direct-fit upstream NOx sensor for Volvo FH13, FH16, FM9, FM11, FM13 & FMX Trucks (2013–2024) using part number 22827991
Cross-Reference: 22827991
Installation: Installs in the exhaust stream upstream of the SCR catalyst; professional installation recommended to ensure proper torqueing, routing and ECU adaptation/clearing of stored codes
Service Interval: Replace when NOx-related warnings appear, DEF dosing irregularities occur, emissions performance drops or diagnostic readings become erratic
