Wheres the crankshaft sensor on the V6 3800 engine? I cant find my haynes book and want to check the wiring going to the sensor before I shell out $150 to get it replaced. Thanks.

The crank sensor is behind the crank pulley. The sensor has two grooves in it that the pulley runs in. Make sure the grooves line up or you will ruin the new sensor. It is adjustable so just be careful.
