Camshaft sensors or solenoid

Check oil pressure when cold and see if pressure holds after it worms up, these cars have a VCT (variable camshaft timing). that works with oil pressure, if prssure drops it can't actuvate timing solenoids to adjust the timing and throw a camshaft sensor fault P0010, P0011, 13 or 14. P0010 is intake camshaft sensor. If pressure is ok, could be timing chains or VCT solenoids
