2005 Tundra No Throttle Response

Hello Everyone! I have a 2005 Tundra 4.7 V8. I lost throttle response a few weeks ago. I ran a diagnostic test and got a several codes, all dealing with throttle sensors. I pulled the throttle body off and cleaned it, still no throttle. Bought a new throttle body and new accelerator pedal (since 2005 tundra's have no replaceable sensors, fly-by-wire style) After replacing the throttle body, I still had no results. I replaces the Accelerator pedal assembly, all codes cleared and it ran GREAT for 1 day.
Now its back in limp mode and I now have Code: P2118 (Throttle actuator control motor current, range performance). After everything I've read, I've checked: Wire/Continuity; Good. Fuses; All Good.

Any Suggestions??????

Have you checked the APPS & Tps signals at the pcm, also check the output signals to the throttle body actuator, the code tell me that the TBA motor is pulling too much amperage, if all checks out with Apps, tps then I would suspect TB shaft is binding causing elevated amp draw (Just because new doesn't mean it is good) N. E. W =Never Ever Worked! 🤔
