Like the title says, I had P0236 and P0237, couldn't get rid of them, I replaced the MAP sensor, reset the APPS about a million times, bought a new one, installed it, and I still had the dead pedal issue. My buddy told me to unplug my Comp box from the MAP sensor, and lo and behold, my dead pedal instantly solved itself! So, the good news is that my truck runs like stock now, but what I'm wondering is is it for sure my Edge Comp, or could it be the harness?

 

Id send it all back to Edge and let them test it.

 

This sounds similar to what I have going on, only.. no edge. I unplugged the MAP, took it out, cleaned it, APPS reset. Still dead pedal though. Ideas? I don't want to have to buy a new MAP if it's not what is wrong. I have a P0234, P0236 & P0237.

 

Didn't have the CEL for a couple of months, but today it's back with the above codes. Could a wastegate problem be causing this?

 

Got the same thing!!!!!!

 

I installed a Raptor 150, DS, and 1/2" big line kit a month ago. No more codes, no more hesitation or dead pedal.
