I am getting cel and code P0237 and slow boost sometimes. It will be slow to get to 10 psi then will jump immediately to 30 psi. I disconnected the quad box and it is even worse boost the truck cant get out of it's own way.

 

Sensor is shot. Dealer is the only place to get one (I know cause the same thing happened to me).

 

The map sensor?

 

Yep.

 

Thats what I was thinking thanks

 

Here's more bad news, $160 for a new one from the dealer. You might get lucky and Cummins will have one.

 

Ya I was pricing them got prices from $107(Autozone) to $212(dealer) found one online http://hoeslidiesel.com/store/page13.html $70 plus ship I will check with the local cummins dealer on monday

 

Now I know where to get certain parts now.

Thanks for posting the link.

 

got a hold of local cummins dealer and they are $77 but have to get it from cummins and may take two weeks

 

That's why I got mine from the dealer. I didn't want to make a 440 mile round trip with the added expense of $100 in fuel. Also didn't want to wait to get one.

 

If Autozone has one, the extra $15 over Cummins or Hoeslide Diesel is better if you figure your downtime. 2 weeks with the code popping up on ya on the highway/freeway, going into limp mode would drive me nuts.

 

Cummins dealer gave me the # of a local diesel shop that deals alot with Cummins will try them in the morning closed weekends.

 

Put my new map sensor in today still getting same problems. Any thing else I should be looking at?

 

trying to figure out what is going on. took apart alot of electrical connections cleaned em and put em back together still having the same problems seems to stutter then takes off like a raped ape n getting cel and code p0237 still

 

removed Van Aaken c3.2 problem went away but I wound up with a new problem the allen screw that holds the plug into the ecm snapped off inside the ecm. Has anyone opened up the ecm and can the plugs be replaced.
