We have a 01 dodge xcab lb cummins w/135k and you will be driving down the road and it loses power. It is like you have lifted your foot off the footfeed. It has a new lift pump and vp44 about 1 year ago and the low side fuel pressure is 15lbs and the volume is good. We put a new ecm from dodge. We are getting a p0234 and a p0237. We replace the tp sensor and map with a good one. The scan tool shows the vehicle load going down to 0 when it acts up. The tach does go down to 0 interm but necessarily when it acts up. We think a cam sensor will take care of that but dont think it will solve our real problem. There is not any performance parts on it yet. Any help would be great!

Look at grounds for all components. ECM, PCM, engine/bat grounds, Ground behind starter, terminals for corrosion, condition of batteries. Look at terminals while replacing sensor also.

Sounds like a crankshaft position sensor.

Take that back. those codes are from the map sensor.

Local shop swore to me it was the apps without putting a scan tool on it but thats not the code I get. Dont feel like spending 500 bucks for nothing. Ill start digging for wire connections.

Try, cleaning or replacing the MAP sensor and make sure the electrical connection is good. Clean the ground connections esp the ECM ground on the block. A little dielectric grease on a clean ground connection does wonders.

Sorry for not posting the repair. We ended up putting a new ecm on it and runs like a champ.
