This morning my malfunction indicator light went on and stayed on. I have an 04.5 CTD with 54,000 miles. The codes it shows are P0191 and P 0088 I am supposed to leave on a 2000 mile trip on Friday pulling my 5th wheel. Any suggestions as to what I could do would be appreciated.

18-005-06 All Flash: DTC correction, turbocharger protection, and clutch durability improvement.
This bulletin supersedes technical service bulletin 18-005-06 Rev. A, dated April 26, 2006. This bulletin applies to Ram trucks equipped with the 5.9L Cummins 24-valve diesel engine (sales code ETH) built on or after June 9, 2005, through and including May 31, 2006. The PCM software has been revised to address the following issues:
A MIL may illuminate due to one or more of the following diagnostic trouble codes:
P0071 – Inlet Air Temperature Sensor Rationality
P0111 – Intake Air Temperature (IAT) Sensor Rationality
P0514 – Battery Temperature Sensor Rationality
P0191 – Fuel Pressure Rationality
Turbocharger durability improvement: Implemented an engine speed limitation when cold, to protect the turbocharger bearings.
Clutch durability improvement: Implemented a minimum engine speed limitation when launching vehicle from a stop, to protect the clutch.
This bulletin involves selectively erasing and reprogramming the PCM (Cummins) with new software.

 

i think you just need a flash to correct the MIL. Do i search for the codes you are getting if you want more info. i think you are OK.

 

This is a list of all of the trouble codes

p0191-fuel rail sensor
P0088-fuel pressure to high

I would check the fuel pressure sensor just to be safe

 

Bringing up an old thread, but I got the dreaded CEL this morning and the p0111 code popped up. If I read correctly up top, there is a dealer flash that would take care of this code. Can I fix this myself or would it be better to take it and have it flashed. Thanks for the help.
