Other possible causes for Code P0016 (https://www.yourmechanic.com/article/p0016-obd-ii-trouble-code-camshaft-position-a-camshaft-position-correlation-bank-1-by-jay-safford) to set include: the camshaft timing is
wrong because the timing chain jumped teeth; the camshaft phaser is out of position due to problems with phaser; the
oil has flow to the phaser is impeded due to incorrect engine
oil viscosity or partly clogged passages; and the
oil control valve (OCV) has a restriction in the OCV filter.
On vehicles with variable
valve timing, it's possible that hydraulically actuated devices that
control cam position can fail due to inadequate
oil or the
wrong viscosity
oil.
