Default Map sensor cleaning

Cleaned my map sensor today, took it out and it was full of crud it was very easy to clean with carb cleaner, put a EHM on at about 15000 miles, but didn't do the ORM, until recently. The first time I cleaned the map sensor it was a hard carbon, this time it was a powdery carbon, when cleaned the sensor was orange again, it wouldn't clean that good last time. So I put in a new sensor at that time,I think a GDE tune is in the future.
How often is every one else cleaning this sensor?.

I bought my truck with 42,000 miles. It already was running a ORM and Provent. I cleaned my sensor at that time and frankly it didnt need cleaning. If youre running the ORM you really dont need to clean it. Im going to check it again at 20,000 miles.

I just started doing the ORM this last fall, I can't believe that the egr is putting that much back into the intake. I am going to check it again at next oil change.

I have been blowing MAP codes for a few days, then the CEL goes off for a few weeks. Should I clean the sensor? Also, the mileage has dropped off a lot

I sure couldn't hurt, are you running a provent or ehm?

No, I am not running either of those. What do I have to do to do a setup for one of those systems?

Air sensors are at a minimum cleaned on my vehicle every air filter service interval.

Others items are being added to the routine that are not cited in the standard schedules to further bomb-proof this excellent truck.

It is my firm belief (somewhat qualified by experience with heavy duty machinery) that a scant preventative maintenance schedule lets these bomb-proof motors down.
Despite popular opinion, we are lucky to have the VM motor. It is the micky-mouse pollution control (penny-pinched cause they had to) and penny-pinched peripherals that let us down and these items MUST be maintained.

Many peripherals can be easily replaced with better quality units that match the high quality of this excellent power plant.

AMEN!!! I've stated several times that taking this engine, and surrounding it with the cheap support systems that DC/Chrysler did, was akin to taking a diamond and sticking it up a goat's anal orifice. The engine itself is virtually a miniature Cummins, originally developed to survive in the marine environment.

Dude, IMHO, you'd be well advised to stay as far away from GDE as possible - go with an Inmotion Stage II or Rocket Chip tune. For the sake of civility and not starting a flame war, I won't post here why I'd advise against them - if you'd like to know why, PM me and I'll fill you in.

What is the ORM? I also see EGR mentioned here. My CRD ran out of fuel and ever since, the Check Engine lite is on. I bleed the air out of the fuel filter. The engine did cough a few times as it ran out. I have 55K on it. Sounds like I have something that needs to be cleaned. I have not gone to see what the code is.
Thanks for any pointers
