P0237 Map sensor voltage to low...
 

Any one eles have this coad. It has happen to me 2 times now and one of those was on the track at about 280 foot mark!!(sets the truck into limp mode) it took several times of trying to clear the coad before it would clear. Yesterday after clearing coad drive it around and got no CEL. Any thoughts?? I got the ecm pin outs and am going to CK the wireing...

If its that intermittant I would say that 99% of the time it is a bad wiring connection.

Ive got it twice, but had no problem clearing it.

Ok i finally got time to mess with it took all of about 5min to figure it out.
What happend was when i put the Q-zilla boost fooler the boost signal wire termal got pushed out of it cavity I got to looking at the male end of the fooler and one of the pins was slighty bent inward. I have been running it this way all summer. but its fixed now..

The other thing that will throw that CODE is to leave the IAT sensor unplugged when you start the truck. I did it the other day and it through 4 codes...

I started getting this code about once a month. Changed the map sensor out and it was fine for about 2 months and now its back to once a month. Even the local Dodge guys can't seem to firgure it out, its been there 3 times now.
