No, you can't relocate the sensor and have it work properly.
No, for sure you can't zip tie it way somewhere and expect it to work at all.
Yes, you must follow the torque specs in the FSM otherwise don't expect it to work properly.
Do whatever you have to to get a good grip on that bolt. You might have to employ some large vice-grips if you've rounded off the bolt. Try a 6-point socket with a breaker bar if you can.
Ya know what ben...when I bought my nx...a knock sensor was wired to the ecu,wired up and wrapped with like a baby sock or some shit...never really thought it would or could hurt anything,and its actually ran quite well like this....
Yesterday I noticed the damn sensor was gone!! Nothing connected....i know since I just port matched my intake manifold and cleaned it all up that an orig knock sensor was still there....so this morning I connected it and test drove for a while and the car feels REALY differnt....smoother I guess maybe a lil slower? And it runs richer to redline to 10.1 vs the usual 12.7 ish.....
And I could not get that bitch off there either when the manifold was odff
