Turbo boost sensor malfunction??

Turbo boost sensor malfunction??
2002 3500 dually, 5.9...do these boost sensors go out often...I have initially thought that my waste gate was sticking open but now one of my clints says it might be the sensor. The engine has 285k on it and it has not been tampered with. Is this a possibility for my turbo boost loss?? Doc

Most common issues on these trucks are a slipped intercooler tube boot or one that has a crack in it. What are you getting for boost pressure? Any codes to lead you to believe that the MAP sensor went out?

No codes on the OBD, the boot is in good shape, I have checked it 4 times..Is there a boost gauge that be bought and tried, I have no idea what the present boost level is. The closest Dodge dealer is 90 miles away..

First thing to do would be to get some gauges on that truck. Fairly cheap insurance and are available here in the DTR store. They are a good diagnostic tool. It also sound to me like you are checking only one intercooler boot. You need to check all 4..

Yes..for the following reasons..no codes , lift @ 18 PSI, VP 44 not throwing codes, when I left to travel the Dodge dealer scanned it again, no codes...when I called the dealer the service guy said that the boost sensor will not throw a code but that they fail routinely and to replace it. I do understand that fueling issues will cause this problem..but I do not apparently have this...as for a gauge...no I do not have them installed and most that I know that have these trucks also do not. I come here seeking constructive advice, not condescending remarks....I am not a dieselphobe although I enjoy this truck....I fail to see the need to rack gauges on my dash if I have code feedback and intelligent diesel techs to ask...sorry for asking.

What symptoms/conditions are you having that leads you to believe you are having low boost??
Are you having..
Excessive black smoke?
Loss of power?
Any noises out of the normal?

No excessive smoke, loss of power yes....I have noticed acceleration but nothing like the launch I used to get when I brought the turbo in hard on acceleration, it is like the acceleration in a normally aspirated engine, no launch...like I was used to. I am reluctant to go back to the dealer because once they sense you are unsure....your screwed. Thank you for your input, I appreciate it.

Try cleaning the MAP sensor as a cheap test. I've had a dirty MAP sensor (filled with oil) have a low output on our VW tdi.

This is why it's a good idea to install some test gauges for a diagnosis of a problem. You don't have to get $400 in gauges to do that, simple plumbing parts and an $8 gauge can get to the root of the problem. Diesel mechanics have been doing the same for some time now!

Yea, it is hiillbilly, but to just be able to verify your boost levels it works just fine and doesn't break the bank.
If you cant find local, here are some inexpensive alternatives.

Need 1 gauge and 1 coupling and 2 1/4" compression fittings, and of course, some 1/4" steel brake line at the auto parts store.
