Im replying to several threads on this because that sketch from a manual IS GARBAGE. It is causing nightmares around the world. The knock sensor is under the manifold and a huge loss to replace it by a mechanic. I replaced mine by using the bypass method which I uploaded a good video to youtube there now and already being done by people. (I do not advertise and gain nothing from the videos I do them as a service to the community). I will upload a video today using the above manual sketch as to what garbage it is ITS AN ERROR. Please do not use this reply to do the fix--watch the video with all parts and how to modify the plug in which cannot be purchased. The fix is not bogus--its an acceptable fix with knock sensor being fully functional. Attaching a few photos. Keep in mind that I cannot know for sure your vehicle but if its a 99-2002 mercury villager with 3.3 THIS FIX IS GOOD AS GOLD. I just did it and the code went out and so did the other extraneous codes. "Throttle position sensor--cam position sensor" etc also for this fix there is bad info online saying that tapped hole is 5/16-18 it isnt. The is fix by the way is not my invention--I only improved on a known fix by weeding out errors.
