The throttle position sensor for the your 740il is located on the throttle body housing as depicted in the graphic below (item #2):


As you can see, its right next to the engine oil dipstick.

Thanks for the VIN response,

Your engine is a M62TU, (TU stands for technically updated, mainly because it has an electronic throttle valve)

There is no external potentiometer that is serviceable as in the incorrect graphic I posted earlier.

The 2 potentiometers are internal to the throttle valve assembly itself; you can view this here in this picture, the red arrow points to the internal potentiometer:


If there is a fault in the throttle position sensor, the complete throttle valve assembly must be replaced as a whole unit, there is no separate throttle position sensor.

Thanks, JP
