can nh3 sensor fault

I have a code 5848 with a FMI 9, I see this is a sensor ...

This fault is for you NH3(Ammonia) sensor located in the SCR catalist is due from likely a faulty sensor or harness problem (FMI 9 =Abnormal update rate).Cummins insite is needed to reset this fault and depending on severity or other faults in the system the engine could potentially derate. I would keep that in mind the possibility of the engine derating on the trip. I hope this helps ...

Interfacing MQ137 Sensor with Arduino to Measure Ammonia ...

09/02/2018· Turns out that MQ137 sensor can measure NH3, C2H6O and even CO. But, here I am interested only in the values of NH3. However you can use the same method to calculate ppm for any sensor you like. This graph is the only source for us to find the value of ppm and if we could somehow calculate the ration of Rs/Ro (X-axis) we can use this graph to find the value of ppm (Y-axis). To find …
