Where is Crank Fluctuation Sensor? 1997 Civic DX

Well i got a check engine light and it throws a code of 54: which from online sources is the CFK sensor…
What should i do? should i replace it?
I reset it and its off for like 100miles then comes back on…
I checked the timing is a little off, nothing bad enuff to affect the engine but i will how to correct this and see if the check engine light goes away but if anyone can point me to where this sensor is ust for plan b that would be great thank you.

it’s on the oil pump, you’ll have to pull the crank pulley and the lower timing cover. something may have just rubbed through the wire, it runs right next to the timing belt. Good luck! :tup:

sweet i;ll take a look at it it this weekend.

junk it.

jk.
i miss my old car :frowning:
