have a 2006 5.9 and I have code that will not delete. Autozone print out states P1740,P0238, P0237, P0236 and P013. It says to replace fuel pump. So 3 of them are MAP sensor voltage. I have a MAP fooler in and do not know what to do next.

Help please

 

Was the map fooler installed prior to the codes or are you trying to use it as a part of the diagnostics?

If it was installed at the time the codes occurred, then take the map fooler out of the equation. Clear codes and see what codes return.

Without looking up codes, I believe P1740 is a transmission solenoid code. Torque converter solenoid. I think.
P013 doesn't sound correct, can you verify?
P0236, P0237, P0238 are MAP codes

What all is done to the truck that is not factory?
