Well clearing a code won't fix it if the underlying problem is not resolved. Need to run the car on a diagnostic stand at least to see what is really going on. A cam sensor code may mean a problem with the sensor, or it could mean a problem with timing or the cam. Since you replaced those sensors, then all you can say at this point is that they were not the real problem.
