I just pulled the 03 04 code, which I found out was my Knock Sensor. I have never tried to do any research on this, so I was wondering if someone could help?

Could I still expect the car to perform normally with a bad KS?

Will performance suffer form a bad KS?

Where is the best/most economical place to get a new KS?

What are reasons that a KS goes bad?

thanks for any help in advance.

I would like to know this one too.. I have the same problem with the knock sensor now and when I went to buy a new one the price was around $240.. so I needed to know how quickly it needs to be changed..

 

If its just a bad ks you will get bad performance but usually there is other things that may be wrong.

I bought my KS at nissanpartstore.com for 110.00

From what I can say with my experience with knock sensors, is that when the knock sensor "senses" somethign in your engine thats not suppose to be happening, it sends a signal, which then "retards" the timing, so that in the furure there can be no damage. By "retard the timing" I mean that your idling might feel bumpy and weird, your acceleration wont be smooth, you will feel loss of power, and others. It does a lot of bad things, but ti does it to save your engine. Just my 2 cents.
