Cam Shaft Positioning Sensor
 

Is this DIY material? Tried a search and found nothing.

Any tips on how to replace from any one who has done it before?

This is a 15 minute DIY with the right tools - I did both of mine this past spring. Go to sears and get a cheap set of torx bits and you should be all set

In the picture, the red circle is where the cam position sensor is located. The plug in the blue section can easily be moved for easier access. The picture is looking at the engine from standing directly in front of the car, with the sensor slightly off to the left of center. You will need to remove the plastic shroud to access underneath.
