I have been getting this code ever since they reflashed my truck with the flash that does away with the EB sensor.

I know the code is injector control pressure regulator circuit/open.

The truck is running great and is getting the same mileage (finally) it did when it was new.

 

Do you have a tuner? I have had the same code. I changed my fuel filters and put the tune in a lwer setting and havent had a problem

 

SCMT 1704 I wondered about that, it also acts like it starves for fuel around 70-80 with the HP mode installed.
