MIL Light ON

[aza]

I have a 96 mazda mpv 3.0L v6. My MIL light is on and car will not start. I pulled a code and got this code:

P0335 crankshaft position sensor A circuit

Does anyone know the location of the sensor?

The actual sensor cost more than $150. I'm wondering if a used one from junk yard would be better?

EDIT:
I found the sensor and I took off the sensor, but how am I suppose to test this? It's a two wire sensor (blk/red and wht/red).

EDIT 2:

FIXED PROBLEM
