Dd13 spn 3251 eec 61 02 code for dpf pressure

Hi I have a 2013 Cascadia. it's showing fault code eec 61 spn 3251 dpf pressure 02 . there was check engine n malfunction indicator lamp on but check enine went away. Is anyone familiar with the cure to it . and how far I shd or cld make it with this situation.

Thanks in advance

 

Yeah i got it fixed. It was def pump. Around 900 dollars with installation and a two year warranty on new one.

 

It very well could be a sensor.. i drove over 1200 miles after the check engine light popped up. But never derated on me. Eveb if it did .. pulling the speed sensor off was next on my list.. wish u all the luck in the world. Hopefully you just make it outta there with only a bad sensor
