2008 Dodge Dakota 4x4 4.7L Throttle Position Sensor Location

That's the "fly-by-wire" electronically-activated throttle body used on 2008+ models. The round horizontal cylinder-shaped piece on the top of it is the drive motor which opens/closes the butterfly, instead of a throttle cable (with a linked Throttle Position Sensor) like on earlier models.
Yours would have an Accelerator Position Sensor under the dash, which tells the electronic throttle body what position to open the butterfly...The actual sensing of the butterfly's position would all be contained within the electronic drive assembly, not in a separate sensor like the earlier models.
(There's also no IAC or separate cruise-control cable-linked vacuum module on the newer models...The electronic butterfly drive motor handles all of the above.)

Now for the OP, is there a particular reason you are trying to access the TPS? Troubles or issues you may need help with?

Thanks for the replies. I am experiencing some surging in idle from 600 to 650 rpm when the engine is warmed up. I was reading on the forums that the usual culprit is the throttle position sensor.
I haven't thrown any codes, but I have tried running seafoam to clean the throttle body, and checked for vaccum leaks that best I could. Will probably change spark plugs this weekend.
