This one was $85 shipped, and just got installed last night.
Words to the wise:
Words to the wise:
- Use the 3/8" extension with the 3/8" U-joint - I shattered a 1/4" U-joint
- Once you get the bolt loosened, get someone with small hands to get it all out. My hand looks like hamburger meat, but being 6'3" might have something to do with that.
- Be careful when you are replacing the sensor - the plug has a little copper-looking "staple" (for lack of a better term) that you have to pull off first. I chipped my plug without realizing what was going on.
- Lord this thing moves now...I wouldn't have figured on that much of a boost in pull.

The cheapest I've seen a knock sensor online (though not looking too hard) was ~$125 (nissanpartstore.com), so yah, hit ebay first.
FYI for anyone who may be interested, there's a way to test your knock sensor before replacing it.

thanks for all the help - I ended up getting one off ebay for $77 and change shipped 2nd day. Ebay is definitely the best place to find one when yours is bad.
Yes, I did have a code flash up, 3 actually. One was for the knock sensor (0304) and the others were 0302 and 0111. I tested the KS about a year ago and knew it was bad, just too lazy to replace it. I can't wait to see what the old maxima is gonna feel like with the new one. Time to fill the bottle!!!
Thanks again for the help, I would've ended up paying about 140 for that POS before I checked here.

on the connector, there is a metal clip that looks like a large staple. You need to remove this before you unplug the connector. All you need is a knife to remove the "staple". After it's removed, you can easily unplug the KS from it's harness.
edit: BTW, I replaced mine last night and I can't tell any difference yet in power but have only driven about 7 miles. The check engine light hasn't come on though, so hopefully I will feel some changes in the next few days.

I didn't think I could get a good shot at the opening without removing the valve. I got the hoses off with twisting and patience though they are fragile from years of heat. If you take them off make sure to put the hoses back to the original ports. mark them somehow. This valve switches the pressure sensor between ambient air pressure and manifold pressure. Your ECU could be very confused if you switch a couple of hoses by accident. If you did tear the hoses though they'd be easy to replace as they are just short hose sections between metal piping in that area.
