Need some help resolving a couple of fault codes before I resort to calling Cat field service.

 

Background: Unit has not been operated since anomalies noted.

Engine starts and runs normally.

No Active "Events"

No diagnostics data

All service intervals well within spec

Diesel filter clean cycle should be over 1000 hours in the future.

Periodic regens occur normally.

 

The issue: message appears at startup, warm or cold:

"Aftertreatment #1 DPF Trap Differntial Pressure Voltage Above Normal,  3251-3 Engine", and 

Yellow " ! " blinking on dash

 

Logged code history  is E871-1 without date.

 

I've been unable to find documentation to address these events....HELP???

 

 

 


The code indicates an electrical issue with the DPF differential sensor. Typically it is a bad sensor that needs to be replaced.
