Knocking! Was: P0455 code fixed, or not likely?
From : jmc
Q: suddenly without warning mike simmons exclaimed 8/1/2007 1000 am suddenly without warning mike simmons exclaimed 7/31/2007 750 pm just wondering if its possible that it was actually the muffler that was causing the codes and if someone could explain why. twig said he thought it was unlikely that the system could sense that far down the system to throw this code because of a muffler problem. the exhaust system will not cause that code. the check engine light will i fear return. your truck is equipped with an obd ii diagnostic system that performs periodic self tests. after three good self tests the check engine light will turn itself off. thus if the problem was no longer there the light would have self extinguished by now. sorry to be the bearer of bad tidings. mike waaaaah! now look youve gone and made me cry! i was hoping though but i know that ive had the code for a lot longer than the seriously rusty muffler. how often does it run these self-tests so youre saying i shouldnt reboot my truck after its fixed i should wait and see if the code goes away on its own jmc either way. if the tech clears the code after the repair and the light doesnt come back on voila! if the repair is made and the light goes off after several days of driving voila again! the self=test isnt performed at each start up. an obdii drive cyle must be completed before the self-test runs... usually a couple or three days of normal driving will do the trick. mike thanks. the light hasnt come back yet ive driven about 40 miles today its been started three times. ill keep an eye on it. worse though i think my engine started knocking! noise is in the right side of the engine block as i face the truck a tickticktick noise at about two ticks per second. i noticed it as i arrived home today. can only hear it at idle. shut the truck off went back out just now about an hour or so after turning the truck off. turned it on no tick. as soon as i revved the engine a little though the tick started again. i suspect it starts when the truck gets warm. its not really loud but can be heard inside the cab when the windows rolled down. knock is serious isnt it i just had the sparks replaced not two months ago. i dont understand why it started up right after an unrelated repair dammit!. how hard is this going to be to fix and is it going to cost a lot is it ok to drive it for short distances until repaired help appreciated! jmc i hate to say this but that is not knocking. engines dont normally knock at idle. that sounds like something more serious. it could be something fairly simple like a failing lifter or something much more serious like a blown head gasket or a cracked head. if it is coming from inside the block then it could be the initial signs of a failed bearing. it is impossible to say exactly what is going on without actually hearing it but i would get that looked at asap. a light tick tick tick sounds more like a lifter then anything else so the is not horrible and that can be left alone if you choose but i would have someone confirm that is actually the problem. -- if at first you dont succeed youre not cut out for skydiving .

z88z wrote hi folks like i said roy have to admit ive done that once or twice back in the day. we must be from the same era - i want to do this swap right so i dont have to fudge anything. i dont think you said what state you are in. ma for about 50 years. now in fl will be back in ma next month. in ma they do safety every year and emissions every other year. thats why this gets kinda crazy. i dont think all the people giving advice necessarily have to deal with the same inspection requirements and practices. for instance a reply elsewhere said that in pa the vin is printed as a bar code on the vehicles registration card too. they do the obdii check and also use a bar code scanner on the registration. if they dont match it will fail. besides im not sure all states even do emissions testing. talked to b&g performance and another guy today. b&g is pretty sure they can help me either way - they can rewrite my jeep 5.9/auto pcm so it doesnt have auto trans parameters at all or they can rewrite the vin on a dodge 5.9/5spd ram pcm. they would have to write custom parameters into either pcm to make it work so im looking at a $430 custom flash instead of a $130 vin flash. if i have to go that route ill use b&g. i talked to another shop in ma that does offroad builds. he said he really didnt have any familiarity with that kind of stuff but he did bring up a good point. he said if i was right that if the machine kicks it back because it doesnt agree with the vin or because the tech cant confirm it then in theory they have made it illegal in ma to use a used pcm. i still think there must be scanners out there that will delete or overwrite the vin on a used pcm. if i go ahead with this i think i will try the ram pcm as it is first see if all the other stuff agrees the abs/seatbelt etc lights. then take it to any station that does inspections and have them run it through the obdii stuff and see what comes of it. hi tbone not sure who you meant about having a diesel me or roy that would be me. the only diesels i drive weigh about 200k - are they powered by emd roy when i get definite answers ill post the info. til then i have a few other questions ill be posting. thanks folks - john .

your truck was a diesel and im not sure if there is an emissions inspection for diesels there. there isnt here in nc just the safety inspection for diesel and older vehicles. -- if at first you dont succeed youre not cut out for skydiving roy wrote the way around it i believe is to find a friend who does the inspections and either manually enter data or put the sniffer inanother car or truck. thanks roy. thats old school. been there done that. showing my age i guess. wont work in this case though. they plug the inspection machine rihgt into the obdii port under the dash. iirc they did not do this last nov. on my truck. roy .

hi folks looking for info from anyone that does emission inspections in massachusetts especially if they have any experience with modded obdii vehicles or input from anyone that has been through any similar transmission/pcm obdii swaps in massachusetts. the way around it i believe is to find a friend who does the inspections and either manually enter data or put the sniffer inanother car or truck. .

suddenly without warning mike simmons exclaimed 8/2/2007 702 pm ok so before you read the next line what do you think it is still dont know.... the not changing rythm with engine rpm leads me to believe its not an exhaust leak... but sigh who knows.... i could be wrong too. its not terribly loud so its easily drowned out by the engine sound when revved so it could be and im just not hearing it... . . . . . . . twigs take manifold gasket thatd mean nosey wins right. you guys agree jmc .

hi folks looking for info from anyone that does emission inspections i massachusetts especially if they have any experience with modde obdii vehicles or input from anyone that has been through an similar transmission/pcm obdii swaps in massachusetts this subject is probably nowhere near as complicated as im making i out to be here but i have a couple of pcm swap questions that i can seem to resolve. the project - put a 5spd nv trans in my 98 5.9 zj jeep. i figure th easiest way is to use a pcm from a 98 5.9 5spd ram. done extensive googling on the subject and done search/faq on abou two dozen dodge/jeep/mopar forums. ive found out a lot but the inf doesnt always agree from site to site and/or im not sure if othe peoples experience applies to the type of emissions inspections w do here just came back from the place i got my sticker last time and h couldnt answer all of my questions off the top of his head becaus he had never seen anything similar done. my vehicle is still stoc at the moment the answers to all of these individual questions arent as importan as the whole idea of whether it can be done or not and how and wha actually comes into play so the main questions 1 - do all states have the same emissions/inspection requirements a massachusetts now that obdii is around if not what other state do 2 - the emission inspection machines in ma reads the vin through th obdii port correct does the tech also have to manually enter th vin and/or verify that it agrees with the pcm vin 3 - any cel/code will automatically fail a vehicle through th machine yes 4 - if a vehicle has cel/codes due to the missing auto trans is ther any option in the machine for the tech to override or ignore th failure that wouldnt really apply since it wouldnt have th automatic in it anymore 5 - the best way around this is to use the pcm from a 5.9/5spd ram 6 - can a new vin be flashed into a used pcm or not chrysler deale says they cant do it but im not sure if thats a they won do it issue or a they actually cant do it issue someone said the enter vin option doesnt come up on th drb if the pcm already has a vin 7 - if the vins cant be easily overwritten used pcms wouldnt hav any value right maybe for use in non-inspection states 8 - do any digits in my vehicles vin specify the transmission type i dont think so if they do - maybe im getting too crazy here does that figure of the vin actually have any input as to how the pc operates or is the vin flash just an internal label 9 - do any other scanners have the ability to overwrite vins or delet them 10 - i know b&g charges $130 for vin flash and $430 for a custo flash. is overwriting the vin considered custom 11 - can my 5.9/auto trans pcm be reflashed deep enough to eliminat the looking for auto trans inputs i talked to b& about this swap but it was at about 459 on a friday. i didnt hav the heart to keep them there answering questions about a swap tha probably had them questioning my sanity anyway - 12 - do the ram trucks have bcms and is that a factor in this swap 13 - the alarm/disable issue - vtss ive heard the pcm from factory alarm vehicle can only go into another factory alarm vehicle a non-alarm pcm can go into either one ill try b&g again sometime soon but figured id post here firs to see if anyone had any experience with similar swaps in mass besides i think most performance flashes are designated fo off road use only so they may not take these inspection issue into account like i said so much info/so many conflicting answers. i know ther can be issues with the seatbelt warning lights and/or the abs light etc others say thats not a problem as long as the pcm has any vi number in it the nuts and bolts of the swap isnt that crazy but i dont want t start buying parts til i solve the last few issues thanks for any replies - joh .

my 96 x-cab 2500 was comig undone around the front. simple and cheap solution but a lot of effort on my part. i removed the entire interior. perfect timing. i had wanted to solve my water leak problem so removing the interior was alraedy in my plan. removing the headliner was easy from there. upholster shops wanted around 125. i called dodge who said they use a well known custom place. blew me away as they do high $$$$ work. i took a chance and called expecting to be laughed off the phone for wanting my headliner redone. nope. $65 and a perfect match. one day service to boot. why a high dollar custom place can redo the headliner for 65 while all the standard auto upholstery places wanted twice as much is beyond me. they scraped off the old and installed new. dodge takes the fabric with foam backing to the edge. this place wrapped it over so it wont hang down even if the glue breaks up in 10 years. of course that made it a little thicker when putting it back together. looks good though. john .
