Registered. There are two NOx sensors so the tech will need to determine which one is bad.
Can I unplug a NOx sensor?
Right now, knock sensors cannot be disabled. unplugging them or not seeing enough noise will result in their unplugging. Knock protection, which prevents timing problems, detonation, and an engine blowing.
How do you relearn a NOx sensor?
Go to the System menu, select Engine, then choose the specifics for your vehicle and go to Functional Tests, followed by Special Functions. At the next screen pick Adaptations then scroll down to find Reset Learned Values Of NOx Sensor Upstream And Downstream Of SCR Catalytic Converter.
Is NOx sensor covered under warranty?

Where is the NOx sensor located Duramax?
This NOx sensor is located upstream in the downpipe.
Can you map out a NOx sensor?
“Mapping out the Nox is essentially the same result as noxem both are fooling the car in to thinking the box sensor is either giving good data (noxem)or the data doesn’t matter (mapped out). Same result two different ways of achieving it.” Coding out out the NOX will enable it to run stratified…
Can knock sensor be bypassed?
When knock sensors start to go bad, you may hear a pinging or loud knocking coming from your engine. If you ever need to bypass your knock sensors, the most direct way of doing so is to simply disconnect them.
What is a NOx sensor on a Duramax?
The NOx sensor is used to check the nitrogen oxide content of the exhaust to optimize exhaust and fuel economy.
What causes NOx sensors to fail?
Most engines feature two NOx sensors: an upstream and downstream sensor. Common causes of failure include soot buildup on the sensor, ECU water intrusion, and/or damage to the cable, which will cause the check engine light to illuminate.
How long do NOx sensors last?
For those who have purchased your vehicle from new, manufacturer warranties for the NOx sensor can vary immensely, with the typical warranty periods ranging from around five to ten years. There may also be a mileage limit to consider.
