After reading some post on this site it seems I have low boost sensor voltage. Is replacing MAP the only cure. I tried cleaning, didn't find much on sensor.:( Sorry forgot to add truck seems to be running find. the only reason I looked for code was got new ScanGague today and it found the code.

Typically yes... But you could check out the MAP sensor error codes... http://mopar.mopar1973man.com/cummins/2ndgen24v/map-sensor/map-sensor-codes.htm

Thanks Mike checked codes per your site. Found 5.0 volts on orange wire. Scangauge goes only ti 8.5 psi on boost. Then trows the 0237 code. Looks like I will be buying new MAP.:(

Well that's a bummer.:banghead: Yesterday the scangauge was showing 14.3 at idle and 23.6 at WOT. Here I was thinking MAP was working.:duh: Looks like I will have to buy a boost gauge after all:duh:

Got my new MAP installed. Since I don't have boost gauge:banghead: I just have to go by the scangauge which shows 13.8 at idle 23.6 at WOT. Maybe it's just me but truck feels like it is running better. Boost gauge is my next wish list item. Thanks for all the help on this site.
