Frequently asked questions about NO X -sensors The NO X (Nitrogen Oxides) sensor is crucial for the proper functioning of an SCR system, but it is also a delicate piece of technology that operates in a harsh environment. As a result, failures may occur more frequently than for other parts in the exhaust system. This sensor is typically a high-temperature device that measures the level of NO X in exhaust systems before and after the SCR catalyst. The information gathered is used by Engine Controls to calculate the exact amount of Diesel Emission Fluid to be dosed at that moment, achieving the necessary reduction of Nitrogen Oxides (NO X ), as strictly regulated by authorities worldwide. All Dinex NO X sensors meet OE criteria and undergo calibration and testing at specialized facilities. These sensors are available for DAF, , Ford, Iveco, MAN, Mercedes, Renault, Scania and Volvo as well as a wide range of off-road applications. What is the Average life of a NO X sensor? About 6,000 hours or 300,000 km (200,000 miles). Does the sensor have the same calibration as OE (ppm levels)? Yes, although generally AEM sensor tend to have a bit wider tolerance zone compared to OE sensors, Dinex sensors are very accurate as OE. Can I drive with a bad NO X sensor? Yes, but the engine might operate in safe mode (reduced power and speed), and the emissions might exceed the specified regulations. How can I determine if the sensor comes installed with the correct software? The only way is to compare Continental cross-references. What is the difference between Dinex NO X sensors and sensors made by other producers? Dinex adds value to the sensor by establishing continuous improvements to the product range to solve problems and guide our customers to make the correct choice. What should I do when the sensor does not work immediately after installation? Double check if the correct cross-reference has been used and make sure all the electrical connections are good. It is also important to run complete system diagnostic to see if there are other issues that could be causing the NO X sensor failure, such as short or open circuit. Other SCR system components can also affect the NO X sensor, such as a pump for Adblue ® .
