Question

P0021 code changed both camshaft sensors should I go ahead and change the crankshaft sensor?

Answer 1

there is nothing else left, if you already changed the oil as well.

Before replacing the valve, change engine oil and filter and reset engine code.

Since the Intake valve timing control solenoid valve uses oil flow to control timing, dirty oil can cause the valve to stuck open or close.
