Where are the Idle air control valve and crank shaft position sensors located. and how do I replace them.

The idle air control motor and valve are located on the side of the throttle body. The crank position sensor is located on the side of the engine.

I do not suggest that you change the CPS yourself as you must perform a case learn procedure once it is changed. The IAC motor unbolts with a couple of screws from the side of the throttle body and can be easily replaced in just a few minutes.
