I just realized you said the engine ticks, that would be the cause of knock sensor code. I would recommend doing a engine flush and switching to synthetic oil to see if that helps if not further testing needs to be done. The most likely cause of ticking is Broken or loose bolts at the crankshaft pulley and/or flywheel. You would want to remove drive belt to see if noise stops when belt is removed if so then check components that are turned by belt if not then check engine related problem. Let me know if you have more questions, thanks.
