At present, the nitrogen oxide compound sensor can only be used to measure the value of outlet NOX. It communicates with the ECM through the body bus. At the same time, there is a self-diagnosis system inside the Nox sensor assembly. The sensor detects its own working conditions and reports to the ECM whether there is a fault through the body CAN bus.
According to the power supply voltage, it is divided into 24V and 12V, and according to the plug, it is divided into five-pin and four-pin.
Nox sensor is composed of a sensor probe, a control module, a connecting plug and a connecting cable.
