Overview

NO x sensor is used to measure the nitrogen oxide discharge of engine control and post-process system.
support vehicles to meet stringent global emission standards. The nitrogen oxide sensor is a unitary device
which consists of two parts. It is a small module which is connected to the metal body of exhaust system
sensor with a piece of wire Parts shall not be separated NO x sensor not possible to repair. If the failure is
confirmed, replace the part.
