Do all 4-tecs have knock sensor adapters? I have 04 /GTX Limited that I bought with blown supercharger. Replaced supercharger, now getting knock sensor fault. Replaced fuel with 93 octane and some octane boost, checked sensor for 5 Megohms and that's ok. Shop manual says check resistance on knock sensor adapter. I don't see that mine has a knock sensor adapter - 2 pin plug from know sensor goes into another plug that disappears into major wire loom. Does it do any good to install a knock sensor adapter? On my ECM connections between contact 9 and 23 I have 5 Megohms. Engine seems to run OK. Fault driving me crazy!
