Look where your throttle cables etc are attached at throttle body, it should be at opposite end of the shaft that operates throttle plate in front of throttle body opening. Usually held on with Torx screws

it sounds me like the app sensor is bad, i dont think tps will cause reduced engine pewer, but app sensor will . u have to replace the trottle body to fix the app sensors uder the hood.
replace the accelleator pedal to fix the app sensors n the cab.
there is a ground wire in the big wire loom behind the intake if u loose ground ull get that reduced power issue i replaced throttle body and accellerator pedle n had the same reduced power few minutes after test drive came back cleared the codes then found a hit on idenafix for ground in the big wire loom ground went to fire wall and was bearly hanging on broke when i touched it fixed it witha crimp on fitting, havent had the code set since

SOURCE: i have a 2006 chevy
You do not have a TPS in your car.. I too have a 2006 ChevyAveo.. We have 2 TPS's located inside our Throttle body.. I had the same problem. I have completely replace the throttle body. IT fixed the problem, but when it gets dirty i have to clean it with carberator cleaner. if you clean it don't spray it into it because you ruin the sensors.. BTW you better have small hands to replace the throttle body, i have to use my camera phone to locate he bolts.
