A) Replacing a knock sensor isn’t necessarily hard work, but it is time-consuming. As long as you think the project over beforehand and label everything you disassemble, you should go fine. The worst thing that can happen is you end up with a loose hose somewhere or have an intake or coolant leak.
Hey. I’ve had to replace the knock sensor and oxygen sensor on my ’95 Nissan Maxima. Same engine, same body style. I actually looked on the web for best way to go about changing the knock sensor cause the service manual calls for the removal of the intake manifold but I knew I didn’t want to go that route. It took alot of patience but I eventually got it off. Refer to this site… ^(.
While replacing the knock sensor, you will need to open the intake manifolds, which will give you an opportunity to service other parts such as valve cover gaskets, spark plugs, coolant hoses, coolant passage plates, etc. Watching out for the above mentioned symptoms will keep your vehicle running smoothly for many years to come.

2. 12mm wrench
6. Flat head screwdriver, or needle nosepliers (to remove harness clip)
