TPS issue.

[Jet321]

Hello gents, havent been on in a while but i have a Throttle position sensor problem, i read the error code and have been looking into it on the interwebs and have noticed alot of aveos have been having this issue, just not the same year. Also my aveo had this problem two weeks ago with an engine light and it went away and came back a week later with same result, and now its back. My question is, should i replace my throttle body because the senors are in it and are not user maintence-able or what would you guys recommend? thanks a bunch.

Error Code:
p2135 Throttle/Pedal Position Sensor/Switch A/B Voltage correlation
