P0103

[WarChild]

It all started back when I got my AFE intake. It was used and had the MAF sensor still on it from the other owner. I started getting turbo performance codes and I knew I didn't have any exhaust leaks so that only left the MAF sensor or the MAP sensor. I started with the MAF since I emerge one I had on my OEM intake was good. I put that on the turbo instantly went away all day yesterday and it was running great and even the lie o meter was reading 22mpg. All was great and I was happy. well my darn egt probe went bad a few days prior and edge was sending.Jr out a new one which got.here yesterday so after lunch today I decided to put it in. Truck was still running great on the drive to lunch but after I installed the new egt probe I took it for a drive and I instantly notice it was driving funny and wouldn't shift right so I checked the codes and the first one I got was a P0102. Long story short I messed with everything I would haves ruched installing the new pro e and even looked at the wiring for the MAF sensor and couldn't see anymore wrong. I cleared all the codes and unloaded my programmer and rescheduled for codes and now I have a P0103 that I can't get to clear. I doubt it's the MAF sensor so it has to be a wire.somewhere. has anyone had this?

Now it's back to the p0102.

Is the 3 gone and only the 2 or do you still have both codes now?

Remove the air filer and hose to the turbo.

Look down and find the wire loom that runs with the frame. It should be laying right on top of the frame. Open it up and see if you don't have wire that is shorting to ground.

Mine did and acted just like yours. I don't remember what color wire it was though.

Just a thought.

I just have the 0102 circuit low. I tested the power to ground and it reads 12.7 but I don't know what other pins need to be tested or what they should rate at.
