without ks!

Shaeff is correct, grounding the knock sensor won’t work. Because the knock sensor is a Piezo Electric device when you stimulate it, as with knock or vibration it produces voltage, somewhere around 2 volts.

That’s all fine but what the ECU wants isn’t the voltage specifically but the signal output of the knock sensor, in the form of a damped sine wave. Different noises will produce different sine wave forms, from rod knock to the motor running each has a specific sine wave form.

Now the ECU listens for knock and detonation, but as I understand it, when it is receiving a RPM signal, it will also listen for the specific sine wave, or the voltage that is produced from the vibration of the engine running, to verify the knock sensor is operating correctly.

If you ground the Knock Sensor wire, the ECU won’t hear, so to speak, the engine running, and it will report a code 52, retard the timing to a preset failsafe, and enrich the air/fuel mixture.

Thank you for your help.

I know it is very unsafe, but I'm curious now. How would one go about removeing the nock sensors from the equation. On an old motor I use to get a code 52 from piston slap. The code would go away when the car warmed up.

 

[boost fiend]

well, my ks code dont show up till in starting to drive. 1800 rpm and higher. AND YES I HAVE RESET THE ECU!

after reseting the ecu, stored codes should not show up unless there is a issue right?

i guess theres a lot to be learned here and some people just need to calm down. ive seen a few people here try to help and it almost always comes off as an asshole attitude. seems like they know so much and want to talk down to the people with ?'s. why is that? we come here for info and we get jerks that want to be all high and mighty, and decide to talk down to the rest of us. im not here for that. im here to learn what i dont know.


now, why some people get to stay and always have smartass remarks towards everyone is just plain bs. is this sf or what?

i think that kind of attitude needs to go somewhere else.

 

[jdub]

I was going to stay out of this, but can no longer stand it.

I've read many, many posts here and on SF...one thing is very consistent, you hear the following comments:

"I've read somewhere..."

"I've heard..."

"My buddy told me..."

What we have in these cases is hearsay...plain and simple. The TRSM is the source of valid information and there are many people on this forum that try to make that clear...the ones with experience have learned through the school of hard knocks. Plus, the search function was put here for a reason...I see the same questions over and over and that makes it appear that the person asking the question was too lazy to look it up. Not to mention, some of the questions don't even make a legible sentence.

The guys on this forum that do know what they are talking about get back talk supported by all the hearsay...it's frustrating...you read the same crap over and over too, as if it's the TRSM itself. Guys put out good info and get called a smartass...or "you're talking down to me"...or they just get ignored.

Hey get over it...typing out words on a forum comes across as you perceive it...this is not the place to be sensitive. Most (if not all) the time the knowledgeable individuals are just trying to help out...if you have to take a couple of hits (lol at) while you're learning, then that's part of it. In my game, slack is a half pair of pants...and coming in second is very bad.

My 2 cents...flame away...I've got my Nomex suit and gloves on.

 

[Godspeed]

well i agree that there are alot of reposting of ?'s. i also think there is too much shit talk going on. as far as the search option, i have tried to use it and came up with no positive answer so i posted to get the right answer before i screwed something up.

once again i would like to thank all of the peeps on here who help[ us out smartass or not. it helps when you need to find the answer for something.

i see jdub's point. but there seems to be a constant "attitude" from several members that act a certian way almost all the time.

yes, the tsrm is a good tool. i work at a automotive repair facility and have found several times that a repair manual is not always right. and thats my .02.

you can search all you want, and if you even go the the point of searching to see what people have said in diffrent threads, they always tend to come off the same.

for example, search for threads that i have posted in. no downtalking. i also do not tell them to learn to search. if they cant find the search button, fine.

but, it you look at others posts, (names withheld to not cause issues) there are several people that will always come off with the whole" if you cant find it, heres my big attitude on the keyboard! this is HOW YOU HAVE TO DO IT!"

we are not here for that. this is a learning comunity. not a "either do it this way or go f your self" comunity. i can do things one way and thats not the way it happend on your car? you have 2k to spend on a turbo and i dont. that does not make you better than me. and i am not better than anyone here. i just dont like to see the additudes here.

 

[lagged]

hey, by all means go ahead, run your car without KS, turn up your boost with 10 washers while you still have a boost leak some where, keep running your car with a rodknock like sabotage or who ever.

just dont come back here and ask why you threw a rod going 80 on the freeway and you car burned down becasue the oil that splashed out the gaping hole in your block caught fire and now were all down one more mkiii.

Sabotage knows she's gonna blow :evil2: I think he just wants to see what happens...LOL. I wish I could video it and post as an answer to some of the posts you see :naughty:

<-- Is back and with a vegance.

Here let me explain the attitude portion. it is not attitude. it is the TRUTH based on FACTS. jdub hit the nail right on the head. IJ gave the answer IMMEDIATELY in post #3 yet here is this damn thread thriving to get an answer to what already has been answered CLEARLY more than once.

yes, the tsrm is a good tool. i work at a automotive repair facility and have found several times that a repair manual is not always right. and thats my .02.

Absolutely correct but everytime GM, Ford, toyota, Honda (yes even them) have spat out a new revision with the correct information.

you can search all you want, and if you even go the the point of searching to see what people have said in diffrent threads, they always tend to come off the same.

There is a saying and I truely believe in it. You have to want to help yourself before other are willing to help you.

we are not here for that. this is a learning comunity. not a "either do it this way or go f your self" comunity. i can do things one way and thats not the way it happend on your car? you have 2k to spend on a turbo and i dont. that does not make you better than me. and i am not better than anyone here. i just dont like to see the additudes here.

Actually yes we are. We are here to share information but you best beileve that if someone does not take thier time to do a simple thing as a damn search, that we WILL point them in that direction first and foremost before we give them an answer. And guess what sometime it won't be nicely said.

Well said. Sugar coating a response is what you tell your mother or wife.

:drink1: to those that dont bullshit.

Ah so thats where I'm going wrong, I need to lie when she askes if her arse looks big in those jeanswned:

 

[Nick M]

She says do these jeans make me look fat, the truth would be"no, your hips do"? I dare you.
