Default P2135

Hey guys We just tried to start up our LS2 Swap today and the Mil light is on. The engine fired and ran for about 5 seconds and shut off. The code shows up on our scan tool as a P2135.

I am running a 06 GTO LS2 with a 06 Trailblazer ECM and the wire harness to match, as well as the TB Pedal. with the GTO throttle Body.

Ant ideas where I could look first?

New harness or modded original? Check for loose connections at the pedal and throttle body. Also check the wires a few iches back from the TB as they are known to break in the insulation.

It is a new harness, I have checked for loose terminals, I cant see any other wiring issues...... Tried another GTO throttle body with the same results.....

Hey guys just to let you know I figured out the problem. The Pedal was pined wrong. F-A instead of A-F
