service engine son light on with p0340 as the code. on 1997 Saturn SL2

I have a Saturn SL2 1997 with the service engine soon light on. I had it checked and the error that was soon was a P0340. I replaced the crankshaft sensore monitor(P0341 which was suggested since my car doesn't have a cam shaft sensor option) as suggested as well as spark plugs,valve cover gasket,thermostat, ect. I reset it and it works for a few mins then the service engine soon light comes back on. I also was told drive it for 100miles or so and it would reset but that has not happened either. What other things should I look into?

This indicates that a problem was detected in the camshaft position sensor circuit. Since it says circuit, that means the problem could lie in any part of the circuit - the sensor itself, the wiring, or the PCM. Don't just replace the CPS (camshaft position sensor) and think that will definitely fix it.I hope this will help you.

so since I have changed the crankshaft position sensor as well as spark plugs, and valve cover gasket what do you suggest me replacing or testing now?
