Take out the air tube that connects the throttle chamber to the air filter box. Set your drop light down under the rubber heater hoses, which are located near the firewall of the driver's side of the vehicle. Shine the light toward the back of the engine block. Below the intake runners on the driver's side you will see a valve cover and the throttle chamber. If you look straight down from the valve cover to the ground, you will see a black wire connected to a sensor that has a green tab on it.

That is the crankshaft sensor. It will be secured to the engine block by a gold millimeter hex bolt. The green tab of the sensor is a plastic clip that holds it in place.

Push the tab down by using a flat-head screwdriver. Push it down toward the engine while you pull the wire connector with your other hand until the wire connector clicks and pulls away.

Luckily the junkyard had a totaled Nissan Altima with the engine wiring still intact. After we cut off the camshaft position sensor wire harness connector, all we had to do was splice it up to the '02 Altima with butt wire connectors.

If necessary, you could also just twist the wires together, wrap them in electrical tape and use cable ties to secure the tape.
