Any other symptoms? other than the camshaft position sensor, I have not seen anything else setting the code. If you have other symptoms, like rough idle, then you may have a problem with timing chain or exhaust camshaft.

The loss of power is definitely a symptom of a bad Camshaft Position Sensor. For your vehicle, the Camshaft Position Sensor it's called Camshaft Variable Valve Timing (VVT) Sensor, and the P0393 code is for the Camshaft Position Sensor 'B' Bank 2 (also called VVT Sensor Exhaust Side Bank 2), From the image below, did you replace the correct sensor? With so many sensors it's easy to get confuse.
