NO CO RE CH ARGES Your Partner in Exhaust and Emission Is my NOx sensor covered under warranty? Yes, of course, there is a 1 year warranty on all NOx sensors. When does my warranty start? The invoice date or the mounting date? It starts from the mounting date. 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 NOx sensor failure, such as short or open circuit. Other SCR system components can also affect the NOx sensor, such as DEF pump. If everything checks out, then submit the sensor for warranty. What is the reason for the sensor failing after a short distance? This indicates one of three issues: • the truck has had poor maintenance. • the installation of the sensor has been completed poorly. • the sensor is defective. Can I drive with a bad NOx sensor? Yes, but the engine might operate in safe mode (reduced power and speed), and the emissions might exceed the specified regulations. What is the Average life of NOx sensor? About 6,000 hours or 300,000 km (200,000 mi).
