Nox Sensor 12V For BENZ car

       Nox Sensor 12V For BENZ car, auto parts 12V Nox sensor, suitable for exhaust treatment of Mercedes Benz. 

       Nox sensor is one of the key components of SCR post-treatment system. It is used to measure the concentration of nitrogen and oxygen in engine exhaust to meet the needs of closed-loop control of engine aftertreatment system and on-board OBD diagnostic system. It can be applied to gas engine or diesel engine. Its structure includes ceramic probe, cable and processing chip controller, which is connected with ECU through can communication. 

The effects of Nox sensor damage are as follows: 

       1. If the Nox sensor is damaged, the diesel control system is in an open-loop state, that is, the emission data cannot be accurately fed back, and the engine control unit cannot accurately adjust the emission. At this time, the vehicle's emission must exceed the standard. If it always exceeds the standard, the service life of tail gas emission treatment equipment will be shortened. 

       2. Because it is a key component for measuring the excessive exhaust of diesel vehicles. If it is damaged or works poorly, it will directly cause multiple fault lights of the engine to turn on. At the same time, there will be relevant fault storage records in the control unit. 

       3. The damage of Nox sensor will lead to the disorder of diesel combustion control, resulting in weak acceleration, idle jitter and failure to start. Once there is a problem, the Nox sensor needs to be replaced in time. It is usually installed at the rear end of the catalyst in the exhaust pipe.
