'06 should have the all plastic pedal.

Re: getting P0120 & P2135 codes
yup, you'd need the molded plastic one. I had the exact opposite problem when I did mine, got the new one needed the old one. Ls1Nova saved me on that one!

Re: getting P0120 & P2135 codes
DAMN! Someone told me I could try to reprogram my PCM to be an 05 and use that pedal/TAC. Do you think it would work? I was told I had an 06 motor, but with the return and reg on the fuel rail and the plastic fuel rails in previous posts everyone thought it was an older engine.
Is the TAC module the same for an 06? |

Re: getting P0120 & P2135 codes
I think there are different part numbers for them. I have an '06 and can check later tonite and tell you if it's an '06 or not.

Re: getting P0120 & P2135 codes
The TAC module you have matches your pedal. It's probably because you have it programmed as an "06. My 2006 TAC has a part number 12590008, so you could either try changing it in the tune, or get an '06 TAC and pedal.

P02135 says throttle/pedal position sensor/switch "A"/"B" voltage correlation If not the harness then could it be the throttle body? When I turn the key on you can hear it click the servo on the throttle body twice. Posted via Mobile Device |

Re: getting P0120 & P2135 codes
I read that, and tried pulling in the wires to see if they stretch and show white, but did not notice any. Maybe I will pickup some wire and replace the wire 12" back. I could try to test it on a multimeter, but don't have any clue what I should be getting @ each pin.

Re: getting P0120 & P2135 codes
yep, I swapped my throttle body out for another and it worked fine. Something was up with the old one I guess.
