Me, I can't imagine that would work. Why would Toyota bury the knock sensor carefully in the center of the block, when dangling it on the lifting hook would work just as well? (Remember, you need to get SIGNAL to the ECU; if the knock sensor doesn't feel anything, the ECU thinks something has gone wrong.)

But, having said all that, I will concede that some on this site claim to have gotten that to work. Including MudHippy, a prolific contributor.

So give it a try, and contribute your vote to whether it works.

93 4Runner V6 knock sensor repair success!

1993 3.0 V6 4runner 4x4 automatic! I successfully relocated my knock sensor to the position on the left side ,driverside, to the lift hook BUT, what happened was it didn't work the first time and discovered the brown wire on the main harness side, that went into the clip, was damaged and hanging on by a couple wire strands. I bought a new knock sensor pigtail from Toyota for $22, repaired the existing main harness clip damage,clipped the new pigtail in but the black single wire was a little shy in length to the new sensor location, so I soldered an extension,about 5 inches of same gauge wire, and attached the round male clip suggested down below from Ebay. I clipped in the new pigtail to the harness and attached the 97 chevy S-10 4 banger knock sensor. I had detached the battery earlier to wash out the code 52 and work on the vehicle. Started it up And it worked like a charm! No code, and smooth running engine! I did not have to attach a ground cable! I repeat, I did not use a ground! I was curious about Toyotas new pigtail wire for their sensor and I took all the tape off and found that the black wires outside grounding braid was attached to the brown wires outside grounding braid and the brown wire was soldered to its own grounding braid and taped up ending the brown wires course! The Black wire with a blue encasement, with braided ground inside it , that lead to the sensor connection end, had about 4 inches of nothing but Black wire going to the clip sensor connection and the blue thicker encasement with the braided wire ended 4 inches shy and its braided ground wire folded back unto itself about 1/2 inch with the black wire exposed leading to the sensor clip all by itself! So the black wire is the sensor wire and the brown wire is the ground that goes nowhere, weird but I have come to the conclusion that the brown wire is already grounded within the harness wire setup itself! Good luck! Toyota pigtail wire harness to the knock sensor is part number 82219-35010 "wire, sensor" and this is the round connector you will use on the 97 Chevy S-10 4 cyl knock sensor...
