Sup guys not really big on SOHC but so im working on a 2000 Honda civic ex and it has a 98 civic motor d16y8 im getting a knock sensor CEL I replace the ECU and KS also rest the KS I haven’t check the continuity on the harness but would the motor be the problem?

 

You replaced the ECU and KS, but havent checked for continuity?

Find a 96-00 Civic Service Manual (you can find them anywhere) and check page 11-170
