Working on trying to decipher the root cause of 2 codes I am getting.


Faultcode: (0x46F9) Reductant active tank temperature sensor signal

Faultcode: (0x4D32) Reductant active tank temperature sensor, plausibility

I have removed the injector nozzle and it was fairly clean only a little crystallization around the actual nozzle...filled def fluid reservoirs.

Any advice?

I looked a a good thread on replacing the seals in the active tank..but thre link to the parts connection was showing not available anymore.

Help Appreciated.
