Where is the cam shaft position sensor on a 2001 Olds Alero?
The camshaft position sensor is right under the power steering pump. Remove the power steering pump to access the sensor.
There is a throttle position sensor mounted to the throttle body. That's the place where the air intake valve sits near the top of the engine. Look for the throttle butterfly valve; on the end of the butterfly valve shaft should be a little sensor with wires connected; that's the throttle position sensor.
