Where to Find the Nox Sensor 2 Location on a 2015 Duramax Diesel Engine

The NOx sensor 2 on a 2015 Duramax is located in the exhaust pipe after the diesel particulate filter.

2015 Duramax Nox Sensor 2 Location

The 2015 Duramax NOx Sensor 2 is a critical part of your vehicle’s emission control system, and provides important feedback on the performance of the engine. Located in the engine bay, this sensor monitors the amount of nitric oxide (NOx) in your exhaust. By detecting and responding to changes in levels of nitric oxide, the sensor helps ensure your engine is running at a safe level and meeting emission standards. The 2015 Duramax NOx Sensor 2 location is clearly marked on your car’s engine, near the passenger side of the vehicle. This sensor is a vital part of your car’s performance and should be checked periodically to ensure efficient operation of all emissions control components.

Introduction

The 2015 Duramax Nox Sensor 2 Location is an important part of the vehicle’s emissions control system. It is responsible for monitoring and controlling the amount of Nitrogen Oxide (NOx) that is emitted from the engine. In addition to being an important part of the emissions control system, it also helps to improve fuel economy and reduce exhaust emissions. This article will provide an overview of the location and function of the 2015 Duramax Nox Sensor 2.

Location

The 2015 Duramax Nox Sensor 2 can be found in the exhaust system, on the passenger side near the exhaust manifold. It is typically located downstream from the catalytic converter, after all other emission controls have been applied. The exact location will vary depending on the particular vehicle model and engine configuration. If you are not sure where to find your sensor, consult your owner’s manual or a qualified mechanic for assistance.

Function

The 2015 Duramax Nox Sensor 2 is designed to measure NOx levels in the exhaust fumes that are emitted from your engine. It does this by monitoring oxygen levels in the exhaust stream and calculating how much NOx is present based on that measurement. It then sends a signal to the ECU (Engine Control Unit) which adjusts fuel delivery and spark timing accordingly to lower or raise NOx levels as needed. This helps to ensure that your vehicle meets strict emissions regulations while also improving fuel economy and reducing harmful exhaust gases like carbon monoxide (CO), hydrocarbons (HC), and nitrogen oxide (NOx).

Maintenance

It is important to periodically check and clean your 2015 Duramax Nox Sensor 2 in order to ensure it is working properly. This should be done at least once a year or every 10,000 miles, whichever comes first. To clean it, you will need a vacuum cleaner with an attachment specifically designed for cleaning sensors such as this one. Simply disconnect it from its mounting bracket, then use the vacuum cleaner attachment to remove any dirt or debris that may have accumulated on its surface or inside its housing. Once it has been cleaned, reconnect it back into place securely before starting your engine again to make sure it works properly before you begin driving again.

Conclusion

The 2015 Duramax Nox Sensor 2 Location plays an essential role in helping your vehicle meet emissions regulations while also improving fuel economy and reducing harmful exhaust gases like carbon monoxide (CO), hydrocarbons (HC), and nitrogen oxide (NOx). It should be checked periodically for proper functioning and cleaned whenever necessary with a vacuum cleaner equipped with a sensor cleaning attachment in order to maintain optimal performance levels at all times.

Engine Compartment

The 2015 Duramax Nox Sensor 2 is located in the engine compartment. It is usually located on the passenger side of the engine. In many cases, it will be near the exhaust manifold. If you can’t find it there, it may also be located near the air intake system or air filter box.

Exhaust Manifold

The Nox Sensor 2 is typically found on the exhaust manifold of the 2015 Duramax engine. This area is easily accessible and can be seen from under the hood. If you look at where the exhaust manifold connects to the engine, you should see a small sensor with two wires connected to it. This is most likely the Nox Sensor 2 that you are looking for.

Air Intake System

The Nox Sensor 2 may also be located on or near the air intake system of your 2015 Duramax engine. This area can be accessed by removing a few components such as a plastic cover or air filter box. Once these components have been removed, you should be able to locate the Nox Sensor 2 easily as it will usually have two wires connected to it.

Air Filter Box

The Nox Sensor 2 may also be located near the air filter box of your 2015 Duramax engine. This area is generally easier to access than other areas and can often provide a better view of where exactly the sensor is located. Look for a small sensor with two wires connected to it and this should be your Nox Sensor 2.
