The NOx sensor A0009053403 is a nitrogen oxide (NOx) sensor used in diesel vehicles. The sensor is mounted in the vehicle's exhaust system and detects the amount of NOx present in the exhaust gases.
NOx is a type of air pollutant that can cause respiratory and other health problems. Vehicle regulations require vehicle manufacturers to install NOx sensors on diesel vehicles to reduce NOx emissions.
The NOx sensor A0009053403 is a semiconductor sensor. The sensor has two electrodes, one exposed to the exhaust gases and the other to the ambient air. When the exhaust gases pass through the sensor, the electrodes react with the NOx present in the exhaust gases. This reaction produces a voltage change between the electrodes.
The voltage signal from the NOx sensor A0009053403 is sent to the engine control unit. The control unit uses the sensor signal to regulate the amount of fuel injected into the engine. This helps reduce NOx emissions from the vehicle.
The NOx sensor A0009053403 fits a variety of Mercedes-Benz diesel vehicles, including:
- C-Class (W205)
- E-Class (W213)
- S-Class (W222)
- GLC (X253)
- GLE (W166)
- GLS (X166)
Symptoms of a faulty NOx sensor A0009053403 may include:
Engine light on
Loss of power
Increased fuel consumption
High NOx emissions
If you experience any of these symptoms, you should have the sensor diagnosed by a qualified mechanic.
Specifically, the NOx sensor A0009053403 is used on Mercedes-Benz vehicles with BlueTec engines. BlueTec engines are diesel engines equipped with an exhaust gas aftertreatment system that includes an SCR catalytic converter. The SCR catalytic converter uses a reducing agent, usually urea, to convert NOx into nitrogen and water.
