How can I fix code po341 on my 05 cobalt?

What is your question?

The car is running fine it starts right up and idles normally. I had a po300 code so I replaced the coil and the electrical component. Now the check engine light comes on but the cars behavior don't change as if everything is fine.l have no noises or leaks. I don't have a camshaft position sensor on this car. I am still getting po341.
