If your car is 2011 then it's the FD variant. The accelerator pedal may operate a cable which goes into the engine bay to the throttle body, so the throttle position sensor may be mounted there. Alternatively, the accelerator may be fly-by-wire, so there's no physical connection. Instead, the pedal operates a position sensor which is connected electrically to the engine control unit and it then moves the throttle to mimic the position of the pedal. If you can bend down and take a look at the accelerator pedal you should be able to tell what type it is. You could also look in the engine bay to see if there's a cable coming through the bulkhead behind the pedal. If somebody can work the accelerator pedal up and down (with the engine off) you should be able to spot the other end moving.
