How do you fix a knock sensor?
How to Fix a Knock Sensor

- Slide a wrench onto the hexagon-shaped part of the knock sensor.
- Smear dielectric grease onto the threads of the new sensor.
Can you relocate knock sensor?
You can’t relocate them. Their location is ‘tuned’ which makes relocation impossible. It’s been my experience that mice like that area of the engine and have a tendency to chew on the wire insulation for the knock sensors. It may not be the sensor but rather a wiring issue.
Where do you mount a knock sensor?
If your engine is knocking or pinging, you may need to replace your spark knock sensor.

Is there a way to bypass the knock sensor?
After researching I’m thinking that if I replace the sensor with a resistor of the same resistance of a working knock sensor the computer will think everything is OK and the DTC will go away. If the engine pings, big whoop de dooo as long as it’s not constantly doing it I’m not worried.
Why does my Nissan club not detect engine knock?
If the engine is running properly, it vibrates the same regardless of worn motor mounts. The mounts just help to isolate the vibration from the cabin. Relocating the KS to get rid of the DTC is one thing but relocating it to where it cannot detect engine knock defeats its purpose.
