Description
Product Overview
Part Name: Nitrogen Oxide Sensor (NOx)
Part Number: 89755-66301
Vehicle Compatibility: Isuzu NPR, NQR & NRR Trucks (2013–2024) equipped with SCR aftertreatment systems requiring a NOx/oxygen sensor in the exhaust for emissions monitoring and DEF dosing feedback.
Configuration: Precision NOx/oxygen sensor module with ceramic sensing element, stainless-steel housing and heat-resistant wiring harness designed for direct integration with the truck’s ECU and exhaust system.
Function: Measures nitrogen oxide (NOx) and oxygen levels in the diesel exhaust stream to enable the ECU to optimize DEF dosing, maintain emissions compliance and help prevent SCR system fault codes or performance derate conditions.
Technical Specifications
Type: NOx/Oxygen Sensor for Heavy-Duty Diesel SCR Systems
Material: Stainless-steel sensor body with ceramic detection core and thermally protected connector assembly
Application: Direct-fit replacement for Isuzu NPR, NQR & NRR Trucks (2013–2024) using NOx/oxygen sensor reference 89755-66301
Cross-Reference: 89755-66301
Installation: Installs into the designated exhaust NOx/oxygen sensing port; professional installation recommended to ensure correct connector engagement, routing and ECU adaptation/clearing of fault codes
Service Interval: Replace when SCR efficiency warnings, engine fault codes, abnormal DEF usage or drivability derate symptoms occur
