ICP failure code

I just replaced my ICP sensor but my check engine light is still on and my sensor and IPR valve are all checking out good the ICP is about 745 psi at idle and then the IPR is at 10% at idle. I have heard the pigtails can go back and I'm going to replace mine tomorrow, but didn't know if anybody else had any ideas on what it could be.

Sounds like your on the right track - 750'ish is default value when ICP is bad or unplugged so if its new then a pigtail could be the problem
