Made by WTR, this 24V O2 sensor accurately measures oxygen and nitrogen oxide in the exhaust, helping keep your truck efficient, on-road and Euro compliant.
It will help limit harmful exhaust emissions, fine-tune engine combustion and prolong the life of exhaust aftertreatment parts like SCR. This sensor is a direct-fit OEM replacement and is designed to offer the same performance and durability as the factory part.
Specifications
OEM Replacement: Replaces OE part numbers 5WK97368, 22827991, 21567737, 21531797, etc. 100% compatible with VOLVO, DAF, IVECO and MAN Euro trucks.
High Accuracy NOx Measurement: Detects the nitrogen oxide (NOx) concentration in exhaust gases accurately, so the ECU can precisely control the fuel-air ratio and SCR function.
Plug-and-Play Installation: Comes pre-fitted with connectors and wiring harness. Installation is easy and fast with no need for modification or calibration.
Durable Construction: Made with a stainless-steel probe and high temperature resistant cable. Built for long life in harsh diesel truck conditions.
