No Throttle Response

[MrBearclaw]

Hey Guys,

I've hit another snag with my LM7 swapped Camaro. The thing fires right up and idles pretty well, but pushing the gas pedal does nothing. Only one code is showing, p2135. Also, I'm getting strange voltages and signals from the throttle body. Here's what is showing at idle:

0% accelerator pedal position (doesn't change when giving it gas)
55% TP Sensor 1
1.08 Volts TP Sensor 1
0.00 TP Sensor 2
2.78 Volts TP Sensor 2

The TAC module and pedal assembly were taken out of the same truck, a Tahoe if I remember correctly. I had to extend the wires to the pedal assembly, but no pins were changed. I tested continuity between all of the wires from the TAC to the throttle body, and everything checks out. Both the TPS and the pedal sensors are new, and I tried the TPS relearn a couple times with no luck.

Moving the throttle blade manually makes TP 1 go to 255% and 5.0 volts, but does not change TP Sensor 2 at all. Has anyone else run into this? Any ideas on what to check next?

looks like TPS is damaged, TAC module is damaged or PCM went south. oh and NEVER try to move throttle blade by fingers etc no mtter if powered on unpowered.

best regards
