How to locate cam shaft
Which engine ? This vehicle had option of six different engines , 2.4 , 3.5 , 2.8 , 3.0 , 3.2 , 3.6 And are you picking on the right part ? What code >

It may not even be a cam sensor problem !

Camshaft Position (CMP) Actuator System
The camshaft position (CMP) actuator system is an electro-hydraulic operated device used for a variety of engine performance and operational enhancements. These enhancements include lower emission output through exhaust gas dilution of the intake charge in the combustion chamber, a broader engine torque range, and improved fuel economy. The CMP actuator system accomplishes this by changing the angle or timing of the camshaft relative to the crankshaft position. The CMP actuator simply allows earlier or later intake and exhaust valve opening during the four stroke engine cycle. The CMP actuator cannot vary the duration of valve opening, or the valve lift.
During engine OFF, engine idling conditions, and engine shutdown, the camshaft actuator is held in the Park position. Internal to the CMP actuator assembly is a return spring and a locking pin. During non-phasing modes of the camshaft, the return spring rotates the camshaft back to the Park position, and the locking pin retains the CMP actuator sprocket to the camshaft

SOURCE: sensor location
The sensor is located on the engine, below the head the near the firewall. It is hard to get to! You get to it from under the car as the intake manifold totally blocks access to it from the top. The sensor causes the check engine light to come on it if the air gap between the sensor and the crankshaft becomes too great or too tight.
The Sensor itself probably is not the problem. There will be an electrical connector going into the end of the sensor and the other end goes into the engine block. It should be held in by two small screws BUT every year of Saturn engine has a slightly different (electrically and physically) Crank Angle Sensor
SOURCE: How do you change a
locate the crankshaft sensor, disconnect electrical plug, make sure around sensor is clean so grit etc doesn't fall in when sensor is out, unscrew with appropriate spanner, replace with the new sensor and reconnect plug. may also need some thread tape on thread before screwing in.
Testimonial: "Thank you, I guess I should of asked where is it located? But it sounds easy enough."
