Read carefully what I wrote before I will write again. I said that I do not have all the answers. Which is the reason why I asked my question so that maybe I could get more knowledge from all the gearheads out there. I was referring to articles that I had read on the internet. When you look things up on the intetnet you get all kinds of different suggestions and usually they are different which is why I was trying to get more input on this issue. Also I am not trying to make myself look smarter than anyone. But I am trying to become smarter on this subject. Which is another reason of why I asked my question. The reason for my cut and paste as you call it (copy/paste) was so that anyone trying to be in this conversation could see why I was asking what I was asking. All because of different suggestions leading or misleading people such as myself. So calling BS on my copy/paste is your opinion and I appreciate it. Which gives me another reason for not believing that it could be done instead of being able to be done with a scan tool. Now as far as your little insult towards my writing and my grammer. Well also an opinion that you can wipe your ass with. Because even though some of my words may be misspelled it's not because I don't know how it's because my thumbs are bigger than the keys on my keyboard which is on my phone. Which is another reason for why people should do some research before jumping to conclusions. Because now you really made yourself look like an ass. Don't try to beat me because you have felt offended from the beginning of this conversation because of how at first I was calling BS on your response from the beginning and I believe that you could detect that. But now you do have me second guessing other people's suggestions on this subject. Not because you said anything intelligent about this subject but because you were the first to respond to this and because you kind of stuck to your guns the whole way through as to not believing that it would work. But if I may quote you, you did say that " you had just never heard of it". But just because you had never heard of it does not mean that it is not possible. I myself had never heard of any of it either which is why I inquired about it. I had other techs in my town that had told me that it was possible and I was in disbelief. Which is why I went to the internet trying to research the lead and one would say yes and one would say no. Which again is why I broadened my horizon and tried to get a G.M tech to shed his light on the matter. Which looking at the headline on the forum it does say "ask a GM tech". That's what I thought I was doing when I posted my question. Didn't know that I was being misled again. Now is that better for you so that your non reading self is abke to sound the words out better. Or was it because since my thumbs were hitting the wrong keys that you were unable to make out what was actually being said. Well hopefully this one was better for you so that you can grasp ahold of what is being said to you. And here's a suggestion for you. The next time that you see something and realize that just because you had never heard of it before does not mean that you know the answer. Just because you had never heard of it before does not mean that it can not be done. Unless that is you are the person that the designer's run everything by before it is actually released on the market and in the tech books for our future techs then atleast maybe do a little research yourself and draw a conclusion with it and then put your opinion out there for the world to see. Which is what I was doing because my opinion to what I was hearing and reading was do more research before I go the wrong way and really take the possibility of really messing something up and have to possibly have to replace a motor or computer for that matter.

Yes I do have my answer and you sir should have been done before you even started. Yes many people are intelligent but no one insulted anyones intelligents. Hence the reason of why I was on here asking the ques backyard tion. To take someone elses knowledge and get another standpoint of knowledge from another person which may have or may not have been a G.M tech and mix that with my knowledge of the wrenching that I have done for almost 20 years now as a lead tech and a service writer and see if that makes me any more intelligent on this matter. Because what do you do class when you don't know for sure what the correct answer is to the aquation. Right you study and research which is what I was doing because I didn't know the correct answer on this matter. Not all knowledge comes from hands on experience. Which is also why the are study books and all kinds of different knowledge on the internet. Which maybe if you would do some more research on what you were responding to then maybe you would be responding with something that pertains to the subject at hand. Which here is maybe something for you to study along with anybody else to study if they would like because someone else may not know the correct answer either like myself. Now maybe we can all move on to better things. Like maybe being able to have an intelligent response to a subject instead of something that does not even pertain to the subject. With all due respect. Have a nice day and try not to scrape your knuckle on the next bolt that you turn on your next backyard job. http://www.bsecorp.com/files/techtipsST9303l.pdf NOTE: If the Crankshaft Variation Relearn is not accessible through your scan tool (some truck applications 1998 & later), perform the relearn in the following manner: 1. Turn off all of the accessories. With the Air temperature sensor and Coolant temperature within 5 degrees (Centigrade) of each other, start the engine and let it idle in Park or Neutral for two minutes. 2. Accelerate the vehicle to 55 mph at part throttle. Cruise at 55 mph for 8- 10 minutes until the engine reaches operating temperature. 3. Cruise at 55 mph for another 5-6 minutes. 4. Decelerate to 45 mph without using the brakes, and maintain 45 mph for 1 minute. 5. Perform 4 deceleration cycles, without using the brakes, of 25 seconds each where no specific speed is necessary. Returning to 45 mph for 15 seconds in between deceleration cycles. 6. Accelerate to 55 mph and cruise for 2 minutes. 7. Stop the vehicle and idle for 2 minutes with the brake applied and the transmission in Drive (automatic trans.) or Neutral (manual trans.) with the clutch depressed. Refer to diagram A on page 8. Supposedly its for all GM vehicles. CoPed 09-19-2007, 01:10 PM You can do the crank relearn without a techII scanner... I've seen it done and thought about doing it myself. It is much simpler then the process you describe and it is no different then when you do it WITH the scanner.....

Yes sir you are right. Anyone can respond to anything that is posted on here. Also if you noticed that I never singled anyone out as a tech. I was looking for a response from a professional G.M tech so that I would get an answer that is more intelligent instead of people that are thinking that what they say is the right and only answer that is available, because just like anyone can post anything on here so does everyone has their own opinion. I do appreciate your view on this topic but your response is very irrelevant to the topic. I never asked an opinion on who is and not allowed to respond to anything on here. I was looking for a professional standpoint on a relearn process being done without a scantool. Which just like everything else that has been brought up now there is a lot of different opinions and results on google about a relearn without a scantool for a crankshaft position sensor hence the reason of why I was also trying to get a professional standpoint. Also, to go along with the whole G.M tech topic and anyone being able to respond to anything on here. If you would look at the headline that goes with this forum you would see that it plainly states "ask a G.M tech" hence the reason of why I was questiong a professional standpoint not some lame answer that was not even on topic or that thought their answer was right and the only option and being wrong.

Yes sir you are probably right about that. Any small shop, backyard, or mobile mechanic probably could perform this as long as they have the correct scan tool. Also, the thing is that I had heard and checked around a little bit before I had brought this to you about being ablr to do a (ckp) sensor relearn "without" a scantool because I believed who would know best that a certified technician that specializes in nothing but G.M product, but I must have been wrong there also. Now if money wasn't a little funny and the change being a little strange then I would have no problem having a shop of any size perform the relearn procedure for me with a scantool, but seeing as the finances are a little less fortunate than others that get paid by the hour to carry a label that they really don't deserve it makes it a little complicated to do so. Which is why I am trying to do the procedure myself. And yes the article that you spoke about earlier that I had posted was a drive cycle. But if you would have actually read it you would have seen that it was about how to relearn a crankshaft sensor. Not to make sure you could pass an inspection. Which yes I am fortunate there because I do live in a state that does not do inspections like. Screw the emissions and computers and bring back the motors of yesteryear which were so much easier to work on and diagnose. A motor from then would not have to relearn anything.

Thank you sir that is very nice reading material. I'll try to remember this information if I ever have to beat a smog test to make sure that all of those sensors are working properly. But I'm trying to figure out what and if I can do a crankshaft position sensor relearn without a scan tool. I did not see anything in that article about a crankshaft position sensor (ckp). I was a little bummed out when I reached the end of that article and never saw anything about a ckp.

It Still Runs › Transmission How to Relearn a Procedure on a GMC After Changing the Crankshaft Sensor So. You have never heard of doing this procedure without a scan tool!! Ok let me ask you this then. Are all the other techs and websites that say they are specifically for GM products just saying that it can be done without a scan tool for whatever reason on the web??? Or is this just something that you have never heard of??? I have spoken to quite a few other techs that I know and that I look up to for knowledge and they also have told me that this is possible to do. Then I started trying to do a lot of research online so that I don't have to keep doing the job over and over again. Hence the reason of why I have also asked you this question. I would very much so rather than to do the job once and get it right the first time than to have to keep doing the job over and over again and at the end of it still be scratching my head and being confused as to why it still is not getting spark and not starting. Especially when it's my vehicle and not getting paid by the hour to work on it and just really needing my truck up and running again.

I'm replacing the ckp sensor on my 03 GMC Sierra 2500hd 6.0l vortec. I know that I have to do a relearn procedure after doing so and I understand that I can do this process without a scan tool is that correct and if so can you give me a the steps on doing it?? Also I heard that I have to bring the number 1 up on top dead before replacing the sensor is this also true?? Thank you in advance for your advice Bruce
