I have a pending DTC that keeps appearing every now and then, suggesting there’s something intermittent happening with the cam timing on Bank 2. I thought I’d investigate further by a) replacing the cam sensor (as they’re not that expensive) and b) pulling the cam actuator to test and clean it. The engine oil last was changed in May this year but, prior to that, it hadn’t been changed for 4 years. I’m wondering if the last change may have flushed out some sludge / contaminants and particles are accumulating in the cam actuator, affecting it now and again(?). The car drives fine and I don't have a CEL coming on.
Please share any experiences of dealing with this issue, as they may help. In the research I've done it often seems to be the cam actuator that turn out to be the problem …
