P0237 after replacing sensor
 

About a month ago I got the p0237 code on my 04 so i checked all my intake clamps and then cleared the code. It stayed off for about a week and then finally i lost power driving down the highway so i replaced the MAP sensor. The other day the same thing happened, the code came one and then went off by itself. Tonight once again driving down the highway my truck loses power. Any ideas on what could be going on? I really don't want to take it into dodge.

Dang that sure sound like a lift pump...but the code isnt pointing there, DO you have a fuel pressure gauge?

looses power meaning it shut off?

no fuel pressure guage. Losing power meaning its a hog on the road, very sluggish.

I was hopeing someone else had a clue on this... Did you check your harnesses from the PCM and ECM?

Haven't checked the harnesses. I think i'm going to take it in today, I didn't get much feedback on here, but thanks for helping buldaawg.
