500 efi knock sensor
 

Anyone know if a knock sensore for a mid 90's gm 454 would be the same as the one on a 500efi?
Thanks

Did not look at every serial number range but found the same sensor for both as 8M0077616 and NLA, old number was 805544T . Is also the same one I use on my 502 and picked it up from Rock Auto.

Guess I can also add, that I know it works correctly. If I run 93 octane I get a code 44, if I run 89 or 90 octane I don't. Still need to switch that code flag off one of these days

Thanks, using some of the alternate part numbers on the link you posted napa crossed it to a dks201. Thanks for the help

I should also add that the 500efi also called for 805544t in the parts look up so hopefully the napa dks201 will be the same frequency. Thanks again
