Hi,
As you stand in front of the vehicle, the lowest and generally the largest pulley is the crankshaft.
As you face the pulley itself, the sensor is located directly behind it.
You should see an electrical harness that is plugged in, running to it.
Unplug the harness from the sensor.
Remove the 1 bolt, and you will now be able to pull the sensor right out.
Reverse procedure to install.
P.S.
Best position for this is on the floor looking up at the crankshaft vs. standing.
Good luck.....I hope this helps.
