Knock/Detonation Sensor
 

Does anyone know where to get a Knock sensor at a good price? courtesyparts.com wants $142 for one :(

id personally save the money and get an apex-i safc II it will tune your car good (if done right) show you everything thats happening in the car, knock, throttle, rpm etc. and i think you can ebay them for like 150 otherwise new there like 350 sooo??? just a thought. probly not what you were looking for though.

hmm, I might consider that... also I was wondering, could an improper signal sent to the ecu by a faulty detonation sensor cause the timing to be retarded, making the engine run a bit rough and lowering milage?

i'm pretty sure a faulty det. sensor in a TT causes safety boost. i'm not sure about an NA, but i would think that could be a possibility.

I will post these for you so you can use them for your viewing pleasure

If you decide you want to replace the knock sensor I would suggest a relocation to the rear plenum bolt and save yourself a $1500 bill from the stealership.

Assuming you ran codes and have a 34

And just to throw it out there, Coz at Concept Z ALWAYS has cheaper prices than courtesy. I'm not "knock"ing (hehe get it?) courtesy or anything, I've ordered from them before, I'm just saying thats how it is.

Yeah I have a code 34 :(

My second advice is to relocate to the rear drivers side bolt that holds the upper plenum to the lower plenum.

needed: A M8-1.25 x 100mm bolt, M8 lock washer, M10-1.50 nut, and M8 flat washer.

This is what some people do and it is fine. Others can argue this but unless you are taking apart the motor then this is a more than ample solution to get you boosted again.

Not such a big deal personally. Then I used $1200 to buy new wheels rather than let Nissan have the cash.

Whats the advantage of relocating?

The advantage is that it will save you a ton of cash. Some people do a resistor bypass, relocate to the back of the engine block or what I have mentioned. The sensor will work at least as effective as the original position. There are no performance gains at all, just in the pocketbook. I have never heard of the knock sensor being a problem for relocating it to the location I mentioned. Would you not rather spend the money on an ECU upgrade and injectors? Or something along that level. I would!

Ahh... I see what you mean... its in the block :(, for some reason I was thinking it was accessable... but after a bit of research, I see... I may just try the 1Mohm resistor to see if it is indeed what is affecting what I think it is affecting, and prolly leave it in while I wait for my new knock sensor to get here

I'm confused....how will a SAFC II help with a faulty knock sensor?
