Truck Repair/help on truck code


I have a 2012 cascadia truck... the code I am getting is 232 spn00170531 I am trying to figure out what that is and what I can do about it...

Most I can find on it is its a DEF pressure sensor. I haven't worked much on the freightliner's with emissions so I don't want to steer you the wrong direction. I would say if they are similar to Volvo that it would be on the back side of your def tank sensing the pressure in your lines going to the exhaust.
