Edge comp install.
 

So I just got done installing an edge comp in my truck. The check engine light won't turn off now. I've double checked all the connections but it still stays on. What do I do?

well were going to need to know what that light is trying to tell you so hook a scanner up to it

P0237 is the code

Turbocharger boost sensor A circuit low

Something to do with the boost sensor connection.

Well the battery cable touched the terminal accidentally when I was installing the edge. The map sensor was unplugged at that time. Would that have done it? Because I drove the truck to o'reillys to get a scanner and everything worked fine with the edge

very possible that caused it and its just a stored code not a current code so if you havnt got it to clear yet it should clear on its own after a few start ups

I cleared it with the scanner and it hasn't come back in the 50 miles since then

cool sounds like your problem is fixed
