n Dodge Ram trucks, the NOx sensor is part of the vehicle’s emissions control system. It is designed to monitor the levels of NOx gases and send a signal to the vehicle’s computer system to adjust the fuel-to-air ratio and other engine parameters as needed to reduce emissions.

A faulty NOx sensor can lead to several issues, including decreased fuel efficiency, reduced engine performance, and increased emissions. If the NOx sensor is not working properly, it may trigger a check engine light or other warning indicators on the dashboard.

Here is a list of OE part numbers for NOx sensors used in various Dodge Ram models:

How to replace a NOx sensor on a Dodge Ram:

1. First, locate the NOx sensor on your Dodge Ram. The location may vary depending on the year, make, and model of your vehicle. Refer to your vehicle owner’s manual or consult with a trusted mechanic if you are unsure of the location.

2. Disconnect the electrical connector from the NOx sensor. This may require removing any clips or retaining bolts holding the connector in place.

3. Use a socket or wrench to remove the NOx sensor from its mounting location. Some NOx sensors may have a threaded nut or flange holding it in place, while others may require special tools or techniques to remove. Refer to your vehicle owner’s manual or consult with a trusted mechanic for specific instructions.

4. Once the old NOx sensor is removed, install the new NOx sensor in its place. Follow any specific installation instructions included with the new sensor.

5. Reconnect the electrical connector to the new NOx sensor. Ensure that the connector is securely attached and that any retaining clips or bolts are properly reinstalled.

6. Finally, clear any error codes or warning lights from the vehicle’s computer system using a diagnostic tool. This will ensure that the new NOx sensor is properly recognized and that the vehicle is operating at optimal performance.

It is important to note that the process for replacing a NOx sensor may vary depending on the specific year, make, and model of your Dodge Ram. Always refer to your vehicle owner’s manual or consult with a trusted mechanic for specific instructions and safety precautions.
