We appreciate this information very much, Paccar should have you on payroll you are an asset to KW owners. THANKS AGAIN my friend, we will be keeping an eye open for anything you have to teach us all.
I just went through this for the replacement DEF sensor for my W800. Why isn’t PAC CAR being held accountable for this issue? I see a class action coming.
i see a class action coming up to certain party...cali and new york are with in these ranks, none of my OP friends will deliver to these states...its not the manufacture, its our politicians being voted in.
G, I can't thank you enough for all that information. Great video 👍 the exact same thing is starting to happen now with my truck so at least I know where to look for the problem, again thank you
I'm in the rental business and we have found from our Houston shop there's a guyaking black boxes that modify the Can/ high/low that shows 6 different codes It's not heat it's a failure in design can't post pics u can install a 1 way diod that will male it read full
Yeah. Cummins. Good motors. BAD EVERYTHING ELSE. Have you actually talked to them? A lot of them are smug assholes. I recently picked up a truck from a body installer. Hadn't even left the lot. He was telling me I was 'One of those guys.' if I had quit driving the second the light came on I'd be able to make it to the truck stop. LOL! I told him the scenario then he told me that because it was a new body on an old chassis I was 'f*****'. These guys LOL!
Had the DEF Quality issue warning. First red def light then the flashing red. Will derate after about 30 minutes driving (goes to flashing red). Also will eventually derate to 5mph even if just idling (2-3hrs of idling).
are you working somewhere i changed so many parts on the def system. I have a kenwort 2016 and if you work somewhere I would love to come this is frustrating and I don't have any more money for repairs ??
Yes I work for a Truck shop. 90% of the time when it comes to DEF code issues on a Kenworth it's rubbed or broken wires. The majority of the wire issues is on the left side of the cab firewall and under the left cab area
So Not to get anyone's panties in a bind.... I work at a sales company. The def quality sensors are a HUGE problem you all know that. Just to corroborate; We(I LOL) have been having to replace a lot of radiators in trucks. You know they are glass reinforced composite anyways. Freightliners end up having lots of problems with the 6.7 isx line. Leaking EGR coolers and there is a fitting halfway down the block on the passenger side that happens to be a turbo coolant return. It leaks a LOT. But only when the motor has completely cooled off. Funny right?. Anyways, overheating is a thing with these trucks.
Before you spend any money because it's not doing a region and high soot level replace the deferential pressure sensor by the DPF. Do not spend thousands of dollars on on DPF filter and shop labor the deferential pressure sensor is easy to replace you can do-it-yourself
Fu*kkk! Im in Houston, and pretty much all Rush centers, KW performace and peterbilt dont have this sensor for atleast next 6-12 months, they're not even taking orders just because they have '100s of trucks all over the services shops and they are also waiting for this part and they need to be out of shops first before they can even began to place order for customers'. As an O/O im running out of options here, even considering doing the you know what..
my truck just went in for this at mhc in el paso and i got the part in 4 days. The catch is your truck has to be down and in service repair otherwise no way to get your hands on one
Just did job tri axel 2021 Pete with mx13 Paccar flat bed. Def tank read empty but full Limp mode 5mph. Got replacement level sensor 338 dollars put it in turned the key gauge read full light went out. Truck only had 26000 miles. I don't know why they made a different kind of sensor like this video has so stupid.
I just bought a 2014 t680 went to pickit up today the def was low I added def fuil after 200 miles of driving it down the red light came on solid, then it started flashing I pull over a d add more def fuel the light went off for about 25 minutes then the red light started flashing again. What should I do, please help

Worse part is that it's not a Paccar design. The engine is actually made by a company called DAF in Germany. It's design was intended for a cab over. The only good thing about this engine is that it gets excellent fuel mileage
Thats like saying all truck drivers are dumb you have absolutely no idea how complex truck systems have become over the years but I guess since you have knowledge of every single system if every truck made thats why your driving one lol have a great trouble free day

The parts in question are made in China I'm sure they won't be held accountable
I'll sign up for that!

Im in houston with same issue, Shop name in houston?
Thank you. Solid info, exactly the knowledge I needed
It evidently isn’t just a paccar issue. I have the code for def tank level circuit failed high. It’s on my 2019 freightliner cascadia with Cummins x15

What was the fix? Having the same issue
thank you for sharing your knowledge with us, it is highly appreciate it
Thank you for this. My truck was in recall for this sucks that I have to buy the parts cause KW service is 2 to 3 weeks out.
I am having this problem with a kenworth t880 2022. I am contacting a lawyer and going after paccar for this
Will this stop the truck from sending any voltage at all to the def level sensor?
What is the TSB number for this?
are you working somewhere i changed so many parts on the def system. I have a kenwort 2016 and if you work somewhere I would love to come this is frustrating and I don't have any more money for repairs ??

Tanks man very useful!!
I have the same issue with the DEF Temp code. 3 weeks and counting for waiting on parts
So far it’s been 8 weeks for me out here in California 😔
Its back ordered ive been waiting 8 weeks also smh
@@bjtherealest4079 t680? 2016? They have 3 of them in denver urea level sensor.
I replaced on my KWT680 sensor and valve and still have light on :(
This is very informative! Thank you
What is the TSB #
Am having this problem. Disconnected and reconnected battery's instead of towing
Thank you man for making this video I'm going to try it out. I have a Kenworth T680 the same problem
This video was created to prevent the same failure again.
I thought it was the vibration screwing with them
Good video
Thanks much
Can I unplug something and just run?
No. The computer will know when something is unplugged and put you in 5mph derate
Abs fuses and abs relay
Only to get you out of the way if you are in the middle of the road

Double yoy!
Its funny how paccar makes this an updated bulletin but dont want to cover their dumb design engineering unless the truck is under warranty
Worse part is that it's not a Paccar design. The engine is actually made by a company called DAF in Germany. It's design was intended for a cab over. The only good thing about this engine is that it gets excellent fuel mileage
You so right,we need to all get together and sue these dealers because the mechanic are dumb
Thats like saying all truck drivers are dumb you have absolutely no idea how complex truck systems have become over the years but I guess since you have knowledge of every single system if every truck made thats why your driving one lol have a great trouble free day
