That has ALMOST zero volts across it. It's very unlikely that your volt meter can measure the voltage drop with such a tiny current going through it. It's part of a low pass RC (R = 4.7kOhm. C = 0.1uF) filter to keep the throttle signal clean.

The current sensor A/D input also has a resistor that has almost zero volts across it. (R6) It's low pass filter is R = 4.7kOhm, C = 0.022uF.

Did you mean the throttle should read at least 3.33v? It sounds like it's not a
0-5k pot, or the board was populated with at least one incorrect resistor value.

Which pulldown resistor is too large?
