Reading a throttle position sensor
Depends. You need a datasheet. Here's a random example from Vishay. Key words are under "output signal":


  Analog ratiometric 10 % to 90 % of V
  supply
   or
  PWM 1 kHz, 10 % to 90 % duty cycle


So yes, you can read it as analogue if you get the right part number. Others send you PWM, which can be read with a different technique on a digital input.
