I bought my car back in November with the knock sensor bad since. Today I replaced the cracked one from one at the local O'Reily store. I replaced it and noticed some power, but when I got it scanned again the P0325 was still there and everytime I "cleared" it, it wouldn't go away.

Is there something wrong with the wiring to the KS or bad fuse? Should I drive around a little while before I get it scanned again? I searched many other threads and couldn't find an answer. Help is greatly appreciated.

 

Typically the harness gets replaced at the same time. It used to be $15 from Courtesy.

 

Are there any other codes?

 

Bypass that bish till you get a new one..

and +1 on harness replacement as well

 

Nope, just the KS one and it's raping my gas mileage which is driving me crazy since I have a lead foot.

If I go to the local Nissan dealership and ask for the harness with the part number: 24079-31U01 would that be correct? I guess it would seem to make sense since when I was putting the KS back, the harness kept making crunching sounds from years of exposure to heat. I just hope I can find where it plugs into w/o much trouble.

 

Check the harness first with a multimeter before you buy one. If harness is good then check the KS again. The KS can be damaged if the bolt is tighten too much.

 

I bypassed mine a few months ago

 

So far, everything seems ok. I went to the stealership and got a new harness and put the new KS on again. I then went to the local autoparts store and got it scanned. The code came up, but this time only once (The previous time the code came up twice). I cleared the code and haven't seen it since.

@Maximized98 By bypassed do you mean the resistor mod? That might be handy if this ever happens again, lol.

 

That is correct

 

How much did you pay for the harness?

 

@NickStam

After my father's discount and tax the part came to be $21.46, before the discount it was $40.

 

WTF, my local dealership said they don't even have used ones and a used one would be $70. Guess I'll install KR first and reevaluate.

 

 

Think i paid $36 for mine.. at the steelership!

Cost more than the KS! lol
