Throttle body, not throttle position sensor.
Typically you will be able to find a Toyota or OEM part number on an assembly like that which you can then google to confirm fitment to specific Toyota models. But it has to be said that it would be somewhat unusual for the throttle body to have failed, particularly with a low-mileage car like yours. (Looking at your previous posts here.)
Are you trying to fix your perceived limp mode symptoms, which you've mentioned here previously? Is this the same problem you identified as a crank position sensor issue a few months ago?
No offense, but you seem to be struggling to get your new-to-you low-miles 2013 S on its feet. Perhaps if you describe the problems you're having, and the associated codes the ECU is giving, somebody here can give you some pointers based on specific experience. That might be more fruitful than throwing parts at it.
