Does anyone know if it is possible to bypass the knock sensor on the vq? i am not sure i am going to do it, if possible, but i would like to consider my options. i am getting the knock sensor DTC, and i feel like the car should be more powerful. i dont want to spend $80 on a knock sensor if im not sure its broken. i am still trying to get a hold of a 10 Mohm ohmmeter, since mine only goes up to 500k or so.

any help or experience would be appreciated

 

You can get a KS on amazon or Ebay for cheap, I've run into no problems with my amazon replacement ks.

 

All you need is a 470K ohm resistor. It's what I did, and I've had no problems.

But if you don't wanna go that route just get a cheap $25-$30 knock sensor off eBay.

 

If you need a KS replaced I can do it without removing the plenum for only $60.00. I am located just west of Chicago. Ted tfvesquire@aol.com

 

alright, did you wire the resistor between the two pins on the sub-harness for the KS? i think i might try it, just because i'm curious, but i will probably end up getting the cheap KS off amazon or ebay

 

I simply plugged the resistor into the green harness at the end of the KS and reset my ECU. The code hasn't come back and my car is running great.

 

Green harness? and how did you "plug in the resistor?" a resistor doesnt just plug in!

 

I believe it's green but I could be wrong. I'll try to take a pic of it in a few.

 

It does plug in lol, you simply put each prong into the 2 holes of the harness. Its easy!

 

LOL sooorryy guys i feel like an idiot. im looking at the male end of the plug.. like WTF?! /// yeah okay sorry bout that

 

I dunno how anyone can do this resistor bypass, fill up with regular gas and sleep well at night! I got the $15.00 KS off ebay, worked out fine. Don't see how anyone can skimp on a $15 buck sensor for a resistor.

 

That's why I fill up premium . I went the resistor route because I cut the **** out of my huge hands just trying to get the socket onto the KS nut, and was never able to replace it.

 

{{{we were able to change out the KS by using and extension and a universal adapter....thank god we didnt have to do what the manual said by removing the manifold! but turns out even tho it was bad and we replaced it....my car is still stalling out and will not maintain idle too long at stops, turns, etc. it just dies out...i even replaced the PCM today.....cuz i finally gave up on the issues and was told by a NISSAN mechanic that it was the brain...but wrong answer....so back to square one again...

 

My wrench got stuck... I think I win number 1 reason to use resistor mod....

 

Take a look at my thread for test results from when the knock sensor is removed and when a new one is installed.
[Test] Knock Sensor OBDII Reading

 

And I am sure you will spend half that on band aid's

They will test your patience for sure

 

bummer, yeah, my dad did the bypass as well which worked out good, but it's apparent that i have something totally different going on so we are on a mission to check out a couple more sensors this weekend, cuz i'm tired of my car choking and dying on me ...and i am not that talented to drive with both feet and shift from drive to nuetral everytime i slow down or stop....just so the car wont die..

 

what codes you got ?

 

only code that came up was the P0325 -and P0505 - we replaced knock sensor....and changed out the IACV - but car is still stalling at idle and no other codes have kicked out again...no engine light on at all...?? oh and gas mileage really sucks right now...i can usually get about 260-300 on a tank....right now i got only 170 and about empty..that is horrible!

 

Chk vacum for leaks around the IACV that just got replaced
to make sure the gasket sealed off
You can use brake cleaner (not as potent as starter fluid) with the car running and all intake system connected spray around the IACV if it is leaking
the engine will race up

 

ok at my wits end here....checked all you suggested...codes cleared out, had already switched brain since nissan mechanic suggested...no go, found corroded ground i think, on sensor right in front of the ECTS..fixed and put clean connection again, also checked ECTS, all fine...test drove & car did not repeat same symptoms of stalling out immediately but choked/hobbled upon acceleration....and had to back off...then attempt again and it recovered....gave up again for a while....came back and checked for any codes just for giggles and got a P0136 oxygen sensor or faulty circuit....so dunno what else it could be, gonna check oxy sensor 2maro..been a long day

Good luck!

 

Thats pretty rough scoobymom, you seem to be having allot of problems with your car. I'd definately try to 02 sensor and if that does not help it may be time for some more drastic measure's such as actually paying some one to look at it profesionally.
