Having DBW issues on new swap
Just finishing up the LQ4 swap in my 71 C10 and I'm having issues getting the pedal to communicate with the t/b.
Getting the following codes:
P1125 - Accelerator Pedal Position (APP) System
P2120 - Throttle/Pedal Position Sensor/Switch ”D” Circuit
P2125 - Throttle/Pedal Position Sensor/Switch ”E” Circuit
Everything is out of an 05 2500HD except the TAC module which is out of an 06 Suburban 1500.
I checked the pins in the connectors(did have 1 apart to get wiring thru firewall) and they're all in tight and look to be solid.
I'm going to grab an ohmmeter on the way home to check for breaks in the harness but beyond that I dont know where to go.
Does anybody have any thoughts or input as to where to start?

Thanks for the respons e- I googled the p/n on the TAC before I bought it and I think it said they were interchangable from 03-06. I'll double check though.
My wife has an 03 Tahoe, can pop the pedal out of it tonight really quick. I planned on doing that with the pedal and the TAC module just to check things out.

In looking at it closer I think it's opening at double speed - t/b is wide open at 1/2 throttle on pedal.
Tahoe has adjustable pedals whereas my pedal is not. I think there were 2 different TAC's used. I found 2 part #'s but can't tell what the difference between them is - 12573059 & 12588923.
Does anybody have any info on the difference between the 2?
