Where is camshaft sensor located on 2003 4.3 vortec

SOURCE: Where is the camshaft position sensor located-99 Chevy Lumina 3.1

It's held down by one bolt right above the timing chain cover. It's next to the head that's facing toward the front of the car.

SOURCE: i dont know where it is

it is located behind the power steering pump. You need to remove the power steering pump to get to it which requires removing the engine mount next to it to get the bottom bolt out of the power steering pump. The sensor is directly behind the power steering pump. You can follow the cable that goes behind the pump. It is the only one there.

At the right rear of the engine under the intake manifold and to the left of the oil filter. You will probably need to go under the car to spot it, it's the sensor with a three-wire connector arranged vertically. But you can take it out from above. It's held in with a single bolt with an eight MM head located just above the sensor. Un-clip and remove the electrical connector. Unscrew the bolt with a socket wrench & extension bar. Wiggle and pull the sensor out.
here is a picture.
