I think the crank position sensor is at the front of the engine just to the right of the catalytic converter. It's the sensor with the 3 terminal connector.
But why would you be looking at the crank sensor to deal with P0016. That's not a crank sensor trouble code. It's a camshaft timing code, so you should be looking at the timing belt and CVVT system rather than the crank position sensor.
If I helped you fix it, why not... Your support is greatly appreciated
