Why do I need to replace my NoX sensor?
In both instances of these diagnostic codes showing up, you may need to replace your NOx sensor. These codes indicate that the NOx sensor A (for U029D) or B (U029E) is not communicating with the other control modules in your Mercedes. The most common reason for failure is a circuit fault. If you experience this issue, you
Why is the NoX sensor on my Mercedes not working?
These codes indicate that the NOx sensor A (for U029D) or B (U029E) is not communicating with the other control modules in your Mercedes. The most common reason for failure is a circuit fault. If you experience this issue, you should get it checked out as soon as possible, as the PCM will no longer be able to check emission levels.
How many NOx sensors are in a DAF truck?
In some cases (such as DAF trucks or in all Euro 6 trucks, such as Volvo, Mercedes, Scania, IVECO, Renault, MAN) there would be 2 NOx sensors (one additional sensor before the SCR system) which would determine the amount of AdBlue needed to inject to have near-perfect NOx conversion. What happens when the NOx sensor fails?
Where is the aftertreatment intake NoX sensor location?
Not too hard of job. Part #22303390 inlet/#22303391 outlet. tserberis Thanks this. Here a photo I have on my phone, see part #.
When do I need to replace my NoX sensor?
Title (customer effect) Selective Catalytic Reduction ( SCR ) Efficiency And NOx Sensor Codes P225C, P225E, P221A, P2201, P103C, P20EE, And P207F : NOx Sensor Diagnostic Information TO BE USED BEFORE SENSOR REPLACEMENT – OBD13 And Newer Emissions (Commonly Model Year 2014 And Newer)
Do you have a NOx conversion efficiency fault?
It looks to me like you do not have a NOx sensor fault at all. NOx Conversion efficiency is more of a logic fault, not a sensor problem. From the limited information I have, I can guess that your NOx sensors are working correctly, but it is not sensing enough of a NOx reduction. Meaning you have a problem in the SCR system.
How big is the NoX sensor on a Duramax?
The mechanical part of replacing the sensors is not a big deal. I can’t tell you if there is some sort of recalibration that needs to be done using the tech II. The ‘sensor’ includes an approx. 25″ harness to a square metal piece that bolts to the truck and has the connector to mate to the truck harness.
