Throttle Code P2138

[Smurfeh]

Alright, been doggin it regarding the truck lately finally started working on it again.. Its been throwing a p2138 code.. only that code. Now I bought a new pedal for it straight from the dealer because I needed one.. No joy.

She fires up and idles fine, no issues there but this one is difficult without pin out diagrams or a test procedure.. I was able to check for 5v signal going to the TB and to the pedal the 5v signal is there at the right pins. unless the PCM isn't doing the math correctly.

5.3 2007 LH6 4L60 I have only 2 of the 7 wires hooked up right now for the harness the PCM power and the fuel pump.. nothing else is hooked up yet.. actually doing that today.. I need some help regarding this code.. anyone experience this before? I'm at a loss without anymore info on testing this system. Thanks in advance.
