Saturns dont have a camshaft postion sensor because the ignition module uses capacitive pickup plates located under the 1/4 coil pack to determine the polarity sequence and voltage amplitude of the cylinder 1/4 secondary ignition. The PCM supplies 5 volts on the signal line and expects to see the cylinder #4 signal wire go low after every 14 crankshaft pulses (2 revolutions). This is used to determine the position of the camshaft. Also when referring to a CPS in a Saturn, its the Crankshaft Position Sensor. And if your getting a P0341 its unlikely it needs a new 1/4 coil pack. Check for corrosion on the terminals at the coil, fouled spark plugs, bad wires or oil in the spark plug well #4. 99% of the time, its one of those four things.
