An Opel NOx sensor is a type of sensor used in Opel (also known as Vauxhall) diesel engines to measure the concentration of nitrogen oxides (NOx) in the exhaust gas. The sensor works by detecting the electrical properties of the exhaust gas, which are affected by the presence of NOx and other pollutants.

The Opel NOx sensor is an important component in the engine’s emissions control system, as it helps the engine to comply with emissions regulations and operate at peak efficiency. When the sensor detects too high a level of NOx in the exhaust gas, it sends a signal to the engine control unit, which adjusts the engine’s air-to-fuel ratio to optimize combustion and reduce emissions.

The specific type of Opel NOx sensor used depends on the model and year of the engine. Some Opel engines may use a NOx sensor from a specific manufacturer, such as Bosch or Continental.

Regular maintenance and replacement of the NOx sensor as needed is important to ensure that the engine operates efficiently and meets emissions standards. If the sensor is not functioning properly, it can lead to decreased fuel efficiency and increased emissions, as well as potential damage to the engine over time. If you suspect a problem with your Opel NOx sensor, it is important to have it diagnosed and repaired as soon as possible.

The OE number for an Opel NOx sensor can vary depending on the specific engine and model. However, here are some examples of OE numbers for Opel NOx sensors:

  • – 55566689
  • – 55502698
  • – 89060413
  • – 93194208
