So it looks like these are new? If so, I think you have a wiring issue assuming each of the components have been replaced. Maybe you told me but have you replaced the throttle body? Even if you have, if you look at the chart for P2135, it says that this code is set when there is high resistance. Clearly this doesn't tell you where but it tells you what you need to focus on when testing these circuits.
What wiring repairs have you made to this point? I would unhook the wiring from the throttle body to the ECM and measure resistance on these wires.
