How to replace throttle position sensor?

I have a 2008 Suzuki forenza,my check engine light is on. The car jerks when i go about 50-70mph and during start up and sometimes stalls. I took my car to autozone and they said that my throttle position sensor is bad. I called the dealer and he said i would have to change out the entire Throttle Body, which parts and labor would be about 750 dollars. Auto zone sells the Sensor for about 65 dollars. So my question is can i go this route or do i have to change out the entire throttle body. If i can change out the sensor, where can i find the sensor on the throttle body and how do i replace it.
Thank you very much for any help.

Yeah looks like the sensor has two screws holding it on and is replacable seperate.My question is how do you know its bad?Because someone that works at a parts counter with a code reader that wants to sell parts all day says its bad just from a code found?Because unless he looked the tps values over on the scan tool ran thru the trouble tree for the code found out it wasnt a wire terminal tightness ecm etc?He is just guessing.

Guessing can be very costly-BTDT when I was a rookie back in the 70's-Now I troubleshoot to determine the problem and the caused of it-Take your advice from Sat9 do it right and only one time

I have the same issue as do many with check engine light on and the codes that come up are the tps and gas pedal position sensor. Many have had the dealership fix the "problem" and still have issues sometimes worse after fixing it.... There is no recalls on this car, I have less than 50,000 miles on mine. Any suggestions on what it could be?? I don't want to take it to the dealership because they have already tried ripping me off so many other times. Two years ago my air bag light wouldn't go off in passenger seat and they said I needed a new battery, went with my gut and didn't replace it and guess what... The battery is still going just fine.

If you get a scan tool that can read live tps and pedal position data and a multi meter we can do some testing.
