I have a dtc for the crankshaft position sensor. I have a 2006 body but have installed a engine from a 2008 Kia Optima 2.4. My question is, where is the exact location for the crankshaft position sensor on the vehicle listed above?

Thank you. I was about to pull the timing belt cover to change sensor. YouTube video said that's where it's located.
Another quick question about the same car. Dash cluster lights, heat/AC, and tail light are not working. Charge indicator light is on in dash. I tested the alternator and it turned out to be bad. Confirmed by auto parts store. My question is, would a bad alternator cause these systems to not work?

I removed the starter motor and I didn't see the sensor there unless i'm totally blind. Enclosed is a photo of behind the starter motor. Looking down from top of engine.

I can't see the sensor. Can we double check the year of the car to make sure it is a 2008? Please post your new question here, you must be logged in.
