ck eng. lgt on again. code 0016 &0017 ?

Question

replaced cam pos. sensor #1 bank 1 week ago. rough idle returned today,very slow accleration,no power.

Answer 1

P0016 Crankshaft position - intake camshaft position

P0017 Crankshaft position - exhaust camshaft position

The main cause for this code is the camshaft actuator solenoid not the camshaft position sensor but  the camshaft solenoid. When there is a intake position code and a exhaust position code, this is aggressive driving it is important you check the motor oil and keep it at a correct level.
