the crank snout bad , causes cam and spark to be timed wrong. (causes cmp to be wrong and ckp to both be wrong)
this is your posted photo. above, below in mine.
the cam spins the distributor so if this is wrong all timing is (was) wrong. crank timing is first, (the key) then cam , then distributor in that order.
the cam turns at 1/2 speed of crank 2:1 ratio. the distributor same. so 2 degrees off at crank is 1 degree off at cam and at distributor.
if timing is not wrong now, then there will be no timing codes. DTC. (unless sensors fail)
as you can see from that very bad key slot above finding true TDC #1 would be not easy. (I'd think horrific task to cure)
it is wallowed out real bad, and the rust there, looks like front of car sat in sea water for a year, wow, never seen so much rust , ever.
here is a good crank snout, mine.

all we know is the CKP will set 335 errors, if the CKP drops 1 pulse in 20 or drops more or all pulse (called dead or wires to it cut)
we dont know if the CMP sensor way off can cause 335.
or if belt timed wrong can. cause 335.
we do know on modern cars the CKP will fail DTC for.
1: timed wrong. ( cam to crank timing incongruity errors we call this)
2: 1 or more missing pulses, or dead.
3: jittering signal (jumping like mad, as any key bad like yours will do)
4: cam belt loose. or timed wrong.
