Ok heres what happened. When i first bought the max used i got a CEL thrown at me and nissan changed, my two O2 sensors and the EVAP canistor, and my Knock Sensor. Well after all of that the car felt slower and juttered in lower RPMs. I checked my ECU today and got 0304 - The ******* ****ing Knock Sensor. A nissan dealership did the knock sensor replacement.....or not. The car has felt laggy and underpowered ever since i changed that stuff at Nissan. The problem is i changed that stuff in 2001, and never bothered to check the ECU. Now i want a free or almost close to free knock sensor and if nissan doesn't give it to me....ill find alot of way to get them back while im in that garage of theirs.

 

Take it easy there dude.

 

how much did nissan charge you for all of this?

 

hehe in reply to my earlier post it seems that i was mistaken about them changing the knock sensor.... They just changed the 2 Oxygen sensors and i confused one of them as being the knock sensor. They charged me around 500 CAD for the oxygen sensors and evap canistor and one other thing i cant see. They are lucky this time....
BTW Does anyone know the proper way to test the resistance of the knock sensor. And can someone confirm that the resistance should be somewhere within the 540 - 560K ohm range?

 

What exactly is an evap canistor? I got that code too once. But everyone told me it was just a piggyback which goes along with other code(s). I ignored it, reset the ECU and never got it again. But I do wonder if I should have addressed it.

 

Well from what those guys at nissan told me its a canistor that gets full of some sort of residue from the exhaust. I have seen people post that they have driven without problem if they dont change it, but nevertheless i did since it only cost 70$.

 

I wonder if this is something easy to do for the home machanic.

 

It's real eazy,it's locate on the driver side rear quarter panel,after the tire.Do the search there is a tread show you how to clean it with wd40.
