Are these DTC codes related?...

[Allie7]

or do I most likely have 2 issues to fix? :

P0010 & POO13 (intake & exhaust actuator solenoids)

Also PO326 &P0327 (knock sensors)

I've been reading about knock sensors and still wonder if the dealer
messed up when they replaced my fuel filter a few weeks ago (since my CEL came on 3 days after). Perhaps air pockets got in and are preventing my engine from combusting and thus throwing codes? The dealer said very unlikely and if diagnostic proved otherwise i'd have to pay. Is there a way for them to
check if it's faulty fuel filter install anyway? I'm confused.

Thank you.

It's really doubtful that the fuel filter is at fault for any of these.

Thanks. Do you have any links/info on where knock sensors are and how to replace them? ARe there 1 or 2 of them?

I don't know much about any knock sensor, sorry.
