Nissan Repair: Cam Sensor and Crankshaft sensor, crankshaft sensor, crank sensor

Question
My check engine light came on so i took it to autozone. They told me i needed a Cam sensor and a crankshaft sensor. How do i replace these myself? Are there any diagrams that you might have. I am new to the do it yourself car repair world. I have a 02 maxima v6 3.5. Do you know of any websites that can get me a quality part for less?
can you please help me

Answer
Eddie,

Yes, it is easy.  Purchase both and replace them.  They are both on the timing cover and you can see them.  The crank sensor will need to be replaced from the bottom so jack the car up and remove the passenger side and the tire and the inner cover and you will see the sensor.
