It should be right at the front of the engine. You don't say if you have a 4 cylinder turbo, or a V6. For the 4-cylinder turbo, there is a black cover on the top of the engine held in by 3 big screws. Twist those 90 degrees and remove the top cover. Then there is the top section of the timing belt cover that is held on by 2 clips. Undo those clips and remove the cover. You will see near the top of the engine 2 bolts that hold the sensor on the engine. It is not a large part, and a Google images search should show you what they look like. Unbolt it, and follow the connector cable and disconnect it. There is nothing special to putting in the replacement other than to torque the bolts correctly. If you don't have a torque wrench or can't find the torque specs, then just make them snug. The head that the bolts attach to is aluminum and it probably needs less than 10 ft-lbs torque. If you strip those bolts, you have a huge problem on your hands, so do the tightening gently.

It might be an issue with the crossover network. A high pass cap may be shorting intermittently. You may also have a loose wire abraiding somewhere.
