DPF Faults - Help - Azcotrucking - Yesterday
Hello,
I have a couple of fault codes that I can’t figure out. Doesn’t seem like sensor issues, seems more like a power issue or ground, or a fuse. I have been told there is a fuse for the DPF that is somewhere in-line around the DEF tank but I cannot find anything.
This is a 2014 International Prostar with ISX 15.
Fault Codes
• 1881 – DPF Differential Pressure Sensor: data valid but below normal range
• 3133 – Intake NOx Sensor: data erratic, intermittent, or incorrect
• 3134 – Outlet NOx Sensor: data erratic, intermittent, or incorrect
• 4151 – SCR Catalyst Efficiency: below normal operating range
Anything you all can think of? Thank you

Looks like an egr cleanup is in order as well as likely the various sensors replaced, they do go bad after a while from the soot.

just some thoughts ...
you might also want to inspect the main harness as it heads towards the engine and across the frame, etc. - The faults seem a bit random and possibly unrelated unless considering a wiring issue in the main harness going back to the engine.
