r/HyundaiAccent

Hey all, got a P0012 camshaft position timing advance, P0132 02 sensor circuit high voltage, P0328 and knock sensor bank 1. 02 sensor P0132 dropped off. A couple weeks ago it was running very poor low power, had catalytic converter replaced and spark plugs which resolved power issue. Later, low oil level and tick came on threw knock sensor code. Cleared code, oil changed. Tick was not around for a week or so now tick is back with these codes, P0012 and P0328. I cleaned OCV and filter. Tick persists, oil levels look full and clean. Found no metal particles when cleaning, no metal shimmer in oil. Any ideas?

I have a 2014 hyundai accent that I was told has some surface rust in trunk pan but rest of the body is still good. What is this rust in the photo? Is it surface rust? do I need a body shop? I have an appointment for a krown application in a few weeks. I live in NY. Can I wait 6 mos to a year for body work?
