Hey,

I need to replace the KS for my '97SE. You orgsters have any recomendations for an online purchase? The stealership wants $212. I've seen it as low as $114, but I'm willing to pay a little more if I have to for a reliable source.

 

Ebay for $90 shipped or http://www.nissandealer.com/jerry-rome/part_catalog.cgi for $112 plus shipping with "maxima" promo code

 

I just got one on e-bay for $90 + $1 to ship! Brand new! From Yoshi Sakura, only took about a week to be shipped, I haven't picked it up yet from my shipping address but I know others on the org have also got them from Yoshi with no probs, there were three, not on e-bay now but does come up from time to time , good luck

 

Yeah that is where I got mine. 90 shipped brand new. Got it in 4 days. Its installed works great. Same ebay guy, Yoshi.

 

Thanks guys. Anybody have Yoshi's contact info? I'm willing to reach out to him. I've seen some eBay dealers(non auto) repost what looks like the same inventory. Worth a shot.

 

what did you search for on ebay because I have only found one and its used by the way I am looking for one too..

 

There are no more $91 sensors on EBAY. He stopped selling them a few weeks back.

 

Wait just a little while and keep checking ebay.
They usually show up there from time to time.

 

Hey T, have you got that promo code? The regular price is $139

 

The promo code is "maxima"...

 

IT's all about the 90 dollar ebay one.

 

...which is no longer being sold. Best option is to go to a junkyard and pick one up for 10 bucks or so. I doubt junkyard owners know what they are worth..

 

There are two on ebay right now. Search knock sensor. Although yoshi is not up there. His was a buy it now for $99. So I bought it then. Glad I did now.

 

Yoshi will be back soon I'm sure I've seen his e-bay ad a few times, he sent mine out on the 17th of May so the e-bay ad must have been the week of the 10th. You could try his e-mail I guess: yoshisakura16@hotmail.com, but I know he posts when he has stock. Just keep checking it's worth the wait , it was for me, up here in Vancouver, Canada with tax is about $190 US! at the stealer.

 

Thanks MaxRB8. I'll email him. As an FYI, I've contacted a couple of local dealers and the going "list price" is $164 U.S. but they will honor a lower price if you can show them the paperwork. I asked him about matching the Jerry Rome online price and if I print it and bring it in, I have at least a good shot at the $139 price. My problem is that I need the KS now. The car is riding like someone poured a gallon of water in the gas tank although nothing registered on the ECU. As in no codes at all. The CEL is on though. Go figure.

 

If you type in the "maxima" promo code and print the ordering page (they may need it with shipping too?) you might be able to get it from the local guys for even less. Also, the knock sensor will have a code so that may not be your problem. I thought you were suppose to get an 0505 (all fine) code at least? Maybe you have a fried ECU or something? That would make the car run like ****. Anyway you may want to start looking into other possibilities before you start replacing random parts.

 

T, your right about that. I took the car to the dealer about 3 weeks ago for oil, tire align and rotation. The CEL was on. They came back to me with " you need to replace KS and O2, and a tune up. They never mentioned the ECU was bad. I folllowed the org's instructions for test,diog and install at least 5 times and I couldn't see anything. Maybe it was too bright out, I don't know. I had the ignition in "On" position but without the engine actually cranking. Does it need to be running for the codes to flash? if so I will certainly try it again before I shell out any $$.
Thanks again.

 

No in the on position is correct. The light just stays solid or not on at all? Are these the directions you used http://vbxmaxima.8m.com/ecu.html? Basically all you do is put the ignition to on, turn the little screw clockwise to the stop, wait AT LEAST 2 sec, turn counterclockwise until stop and the check engine light should be blinking. You can also have autozone run the codes for you.

*Edit* The screw is VERY easy to turn, and you can break the stops, so don't force it at all.

 

You want a good laugh? I was looking at the ECU not the CEL for the codes! What a dumbass I am. It would have helped to read the right one. To be continued...

 

Good for you for admitting your own blunder LOL , unless you are getting the 0304 code don't bother changing the knock sensor.

 

I wish we had a little LCD display on the ECU to show codes. That would be so easy.

 

Exactly - or even a small LED on the ECU unit itself.. its so stupid to have to turn the screw and then crane your neck back up to see what the CEL is doing... at least the codes keep repeating so there is no "rush" to get your head up to see the CEL... Now that would have been a really dumb engineering decision if the codes had only been displayed once...

 

Yoshi with the hookup. I remember buying some NGK plugs off him for a lot less than anything local, and that's even after shipping and currency conversion.

I've been getting intermittent 0304 codes and my acceleration off the line is a bit sluggish, so I was going to get a newknock sensor thru Jerry Rome as it was the cheapest source I could find online. But I wound up getting a new one off another .org member who was selling his.

 

check it out:
Knock sensor e-bay

 

check here:

Yeah, I see, but this auction won't end for another 4 days and it won't get to me for probably another 4-5 days. Thanks anyway. If the 0304 shows up when I check it in the morning, I'll have to move on this pretty quickly as the car is struggling and I'm using it for work. I'm actually driving in the slow lane on the parkway. [Shudder].

This stuff never happened with my '66 Vette or my '71 GTO. Life was easier back then. Too much emissions crap these days.

 

a knock sensor can work or not....but can't it be like worn and get maybe too sensitive? I read a few posts here on org. and on some other auto forums that after replacing a working knock sensor (no code) they still had some improvement in performance.

I also read that tourqe is a MUST on knock sensors and should be around 20 lbs cause this also can make it over sensitive, right?

 

it's $122.73 + shipping with "maxima" promo

 

I have a good used one that i will sell to you for $50 bucks shipped. Pm me if interested. it has 65K on it.

 

Well, I checked first thing this morning and I got 0304, 0604, and 0503.

Lovely

 

OK, here's a question for you all.. Would the 0604(#5 Cyl misfire) cause the 0304, or are they two seperate issues? My thinking is if I replace the plug and it solves the 0604, will the 0304 go away?

 

it could very easily cause it. A misfire will cause engine stumbling which can be picked up by the knock sensor as knock. I'd replace the plug and coil pack if necessary first and then reset the computer codes. if 0304 is still there, then go after the knock sensor.

 

Good advice. I'm going to do all the plugs and then reset. I put way under 10K miles per year with this car, but I love performance. Would you recomend Copper or Platinum?

BTW I got a reply from Yoshi:

I hate to be the bearer of bad news. But, I won't be getting them the
discounted price again. My new price is a wopping $132.99. I don't even
bother listing them on ebay anymore.

yoshi

 

Personal choice, but i am going to use NGK copper.

 

0603 0604 0605 0606 0607 0608
If one cylinder is misfiring the problem is spark or fuel. A misfire due to a spark problem usually results in a Service Engine Soon light and one of these Diagnostic Trouble Codes:
0608 - Cylinder 1 misfire
0607 - Cylinder 2 misfire
0606 - Cylinder 3 misfire
0605 - Cylinder 4 misfire
0604 - Cylinder 5 misfire
0603 - Cylinder 6 misfire

because you only have 0604 code and not the others it seems more likely a firing problem than a fuel problem. If your budget is tight go with the NGK coppers BKR5ES-11 gap=.044, and reset your ECU.

0503
Diagnostic Trouble Code 0503 indicates a problem with the front Oxygen Sensor on the right cylinder bank. The right bank is also called the rear bank. It is cylinders 1,3,5. A normal signal sweeps back and forth between 0.2 volts and 0.8 volts. This malfunction was detected when the Engine Control Module received a signal from the sensor which was a constant value of approximately 0.3 volts.

Possible causes include ...
- Harness or connectors (the sensor circuit is open or shorted).
- Defective Oxygen Sensor
This may be caused by your 0604 code seeing as though we are talking cyl #5. Hope this helps good luck.

One last thought, you are using 91> octane gas??

I once (with another car) put the required octane in after seeing the fill up truck just pull out, my car barely started and sputtered, I had to siphon the gas out and change my fuel filter.

 

I must say that I used to not be a supporter of the 91+ octane gas, but now I am. I was getting some spitting and sputtering and it would hesitate at like 3400rpms at WOT. Well, when I changed my fuel filter and started running premium, it has gone away after about three tanks. No hesitation!

I would try this:
Run a little premium through there and change your fuel filter. That is not too difficult, although the filter can be a little tricky. It is cheap...should be under $10. Also, change your spark plugs with the NGK Coppers.

If that does not work after like 2 tanks of gas...I would try ordering a coil pack for cyl 5. You need to make sure you pull the codes after you have done that other stuff to see if any of them disappeared. If you are still getting a 0604 code, get the coil pack for that cyl. Replace it before you do the knock sensor. This might cure all of your car's symptoms.

 

I'm using Sunoco 94. After my visit to the dealer recently, he said to run it to protect the engine because you can't retard the timing and it could blow a rod or something to that affect and not to exceed 85mph. It's funny because I always use Plus and since I went to the Ultra the car got worse. It would be great if I could replace the plugs and watch the other problems disapear. Id rather spend the money on a mod.

 

You can always start on those cheaper mods and then if they don't fix it, you can go for the more expensive ones.
