Yesterday a buddy of mine wanted in install a 'train horn' in his 2013 or 2014 (whichever). As much as I hate them I agreed to help so he wouldn't burn his truck down. Well, he should have listened to me because man did I screw some stuff up. First I was drilling a hold and in my haste I didn't put a board behind the part and drilled through the condenser. Then after we got everything done he started the truck to leave and the CEL & Wrench lights came on (code to follow). Truck won't move, it's like back in the day if the throttle cable would b disconnected, no response at all.
We hooked a wire to the battery, with a fuse, ran it into the cab and hooked up a relay. Ran the relay output to the horn. Didn't connect to any other fuses or existing wires for any of it. Only had to unhook the headlight & dimmer switches so we could mount the new switch for the horn.

My only guess is that when I ran the wire through the existing grommet I must have cut/stripped wire(s).

Here are the codes:
Stored Faults
012c - Turbocharger/Supercharger Inlet Pressure Sensor Circuit Low (Downstream of throttle valve)
0236 - P0236 Turbocharger Boost Sensor A Circuit Range/Performance
0237 - P0237 Turbocharger Boost Sensor A Circuit Low
06a7 - P06A7 Sensor Reference Voltage "B" Circuit Range/Performance
This type of code is generally provided as support for a more specific code
A stored code P06A7 is normally associated with the drive train

Pending Faults
012d - Turbocharger/Supercharger Inlet Pressure Sensor Circuit High (Downstream of throttle valve)
0238 - Turbocharger Boost Sensor A Circuit High


Anybody have any other ideas what I could have done? I just started looking over all the connections under hood to make sure I didn't bump one and disconnect it but really need some help. Not the way I wanted to spend the BIG 50!!!


Thanks in advance!!

Well not sure what it was but I unhooked the battery for about 10 minutes, pulled the connectors off the throttle body and "boost sensor" and now it's working fine. I did see a few posts about the wiring harness causing issue so maybe that's it. We'll see if ti holds up.

No, not owner. Owner's friend. All is right today. Took about 30 mins to R&R the condenser and a friend of mine owns a shop and he charged it while I waited. I guess it could have been a lot worse. My friend did offer to pay half of it even though I did 100% of the damage. No, I didn't take him up on that.

Did you unplug the sensor right by the air cleaner? Thats what a lot of those codes seem to be referencing.

I unplugged the throttle body cable and the one on the intake tube just behind the fuse box (before the throttle body).
