How to fix 2003 Dodge Cummins P0483 P2509 won't start . The fan clutch is the problem. It will often times start if you unplug the fan clutch plug located on the passenger side of the bottom of the radiator. Once the fan clutch gets bad enough it causes the Engine Control Module to not power up. This causes the no start condition as well as a Diagnostic Link Connector to not communicate. Cycling the key three times will still give you codes on the odometer though. - Авто та транспорт
I’ve been trying to troubleshoot this for months now. My mechanic thought he was crazy cause he couldn’t find anything. Now I have a direction to go, thank you!
Thank you for this video! After spending all day randomly looking at diagnostic videos to figure out what could be causing our cummins to crank, not start, have no fuel pump priming, and a diagnostic tool to not connect, I stumbled upon your video and realized that the fan clutch we just put in (along with a new alternator) could be our culprit.. Sure enough we unplugged the new fan clutch and the truck fired right up and the diagnostic tool connects to the ECM! Everything else seemed to point into the direction of the ECM being faulty.. so glad we didn't have to replace it! Never would've thought that the fan clutch having faulty electronics would totally disable our rig..
My 2003 is throwing 6 codes! Had to jump it to start it. When it would run the volts would drop to nothing. Ended up buying 2 new batteries and changed out the alternator/generator(
No BS just facts and pictures. Thank you for the video man.
@Jolinator The way the computer powers up... you can some times unplug it, plug it back in and then get where you need to be. It won't wipe it out while running, it'll just not re start. This one was hosed with no re start.
Just had the p0483 code thrown at me today, guess what I get to do!!! Your video will sure help a ton!! Thanks a bunch!!!
After spending an hour trying to line the holes up on that fan, I wish i would've seen this video beforehand. Thanks for the great info man.
@evildesl It takes a TON of fuel pressure to start those initially. You have one or more bad injectors that's leaking disallowing enough pressure to start.
@oldie383 I couldn't find any videos on this... so I made this one. As for eliminating it, I'm not sure. I'd do an electric one personally.
Thanks for the video!! Got my friends truck back up and running thanks to you!
@zrultima Check the trans fluid level. If it gets 2qts low or more it may go into "safe mode" including hard shifts and no overdrive.
@kanepit047 You need to try starting fluid to by-pass fuel system. If that doesn't work check for spark and injector pulse.
@SWAMPBUSTERS1 Right. P0700 means computer wiring is chopped or disconnected. P0483 is the fan clutch non communication. I'd check for blown fuses and get fixing the wiring you are aware of.
@haoleboy74 You're welcome- it's a tricky new thing eigh?
Yes. If it's a digital odometer you're good to go. If it's analog you have to count CEL flashes.
the comment about how to get the code was VERY helpful. TY! Was glad to know the truck need not be running to know if the clutch fan is gone or not.
I have never done this job before, and made the fool mistake of not first watching a number of videos on how to do it before I foolishly started removing the fan bolts and the pulley bolts, making it impossible to remove either, and making for myself a FUUNNNN time trying to replace them UGHGHHH!
Just kick me, Self!
Glad to help. Go easy on yourself. Don't listen to the bully in your head. He doesn't know. Just like you didn't know till you looked it up on UA-cam. Now you're doing fine. You're switched on.
@djweszone BS? Beautiful Success.... it works fast without spending on specialty tools that clutter your toolbox and rarely get used. The bite marks made me a critic at first, but some won't come off even with the air hammer. That's when I tried this out of desperation and it came right off. That was 6 years ago. Now I go straight to this method. The air hammer and kit I have/used was a Cornwell at 150 psi.
@zrultima Ok, today I have time to answer. This electric fan clutch is controlled by the computer instead of a two layer metal spring that reacts to temperature. IT has a lot of current draw compared to other components. (too much in my opinion) When it fails it can throw the computer into fail safe mode or create other kinds of glitchy havoc. Another possibility is that one of your eyelets that goes to the + - cable ends got swapped in polarity and did the same thing a shorted fan would.
Great info and just ordered myself a fan clutch from Geno's Garage. The truck currently has both codes and a no start but cranks. So well go ahead and give this a try.
@SWAMPBUSTERS1 I don't do anything. I leave the belt on but the shock of the hammer and chisel are what I use.
@zrultima Doing what again? Not starting?
@bradbodigon You're welcome. You do what ya gotta do right?
You're welcome- good luck man!
@JKBassFishing It's a pretty crazy scenario eigh?
@bradbodigon As a general rule you NEVER use ether on these. It's really hard on them due to a lack of lubrication that the diesel fuel would normally supply/provide. STAR, STAR STAR IMPORTANT If you unplug it, it may reset and start for you.
@moofushu Yours is a more common and better design. It's based on temperature like an engine thermostat is. You have a spring that is made from two different kinds of metal that react to heat. Yours is a "fan clutch" because it has a clutch that engages and disengages. Google a video on thermostat boil demonstration. It will make more sense.
Enjoy your watching your programs I like how you explain things , I do have a question about my 2003 Dodge cummins 5.9 it has around 150k and It getting long starts, It just started doing this about 2 months ago , I first thought it the winter and diesel's are cold natured anyway. But we have had a few weeks of warm weather 50's and 60's even has been is the low 70's and the truck still takes awhile to start. could this be because of the fuel injector? I see a lot of diesel fuel injector cleaner on the market, That you add to a tank of fuel and burn it as you go. Have you used any of these and are they worth wasting time and money on? I know you cant diagnose my problem without looking at the truck, I was just wanted to pick your brain about my thought process. I'm going to replace air filter and fuel filter just as a first step Not sure how often fuel injectors need to be cleaned and if the fuel cleaner that you add to the tank works or not. I have watched a few videos on line about removing the fuel injectors for a hands on cleaning it looks very straight forward . If decide to do this task I will only remove one at a time for servicing that way if I destroy one I have only one to purchase . BTW I have only one error code on the truck that is P0633 which is about the Key immobilizer which the local dodge dealer said at one point the truck was started and the computer got a bad reading from the chip in the key . I know way this is happening a few years ago someone tried to steal my truck which the immobilizer did its job and didn't start for theses guys. but ever since that event I now can start my truck and while the truck is running remove the key and lock the doors this is great for winter warm ups. So the p0633 code is from my winter warm up runs . I was also thinking I need to check fuel pressure at the fuel rail. Sorry for being so long can you think of anything else I need to check? BTW I do not plug in my truck when its cold we rarely get below 20 degrees. Any thoughts you have would be great Really enjoy your channel you have shown me things that have made working on my cars and trucks easier and save me money. THANK YOU !

@zrultima I don't know man. I'd check with a transmission guy you trust and see what he says.
@Hermanvogel I'm like you- I REALLY DIDN'T LIKE the chisel idea when I was taught it seven years ago. I didn't like the marring to the nut or the hammer concept. Having used it for seven years I find it doesn't adversely affect operation or longevity of the pump or fan clutch. AND no one cares what the fan clutch nut looks like and it's ready to go the next time.
@MrChrischichester I'm glad I could help!
Excellent video, you helped me A LOT!!!
thankyou for taking the time to do video's like this!! my question is this, with my 2008 dodge ram 3500 cummins with 200000 miles it seems the fan will come on late like it still comes on I would just like it to come on sooner, now maybe the fan is fine and there is other places I should be looking or is the fan getting to the age of being lazy?
thanks for the video man.. I'm going to get a new clutch fan sensor tomorrow. I'm hoping its the fix.. sure sounds like it. same issues.. same codes..
cheers either way..
@pablobzr Sorry, I need more information. That didn't make any sense to me. Please try again.
Great info and just ordered myself a fan clutch from Geno's Garage.
@zrultima It could be.
@supercannon2 Dude you GOTTA make a vid of that! I wanna see it!
@zrultima Eyelets at the battery.
I have a 2006 cummins, I do not know if it did starts before or not, but it does not crank at all. I have two new set of batteries and all the connections are good. I want this machine to crank, but it will not. I do have the P2509 code on my scanner tool. I also have B210D, U0184, C2100, but not the P0483. Please tell me how can check if the fan blade is good or not. Should, I tow it to the dealership and have it diagnosed?
@spelunkerd yep.
awesome job very impressed do you know much about codes po243 waste gate and po463 fuel level
Computer controlled injection. When you push start it, it thinks it's already running. When you key start it, the computer refuses to add fuel till certain conditions are met ie. a certain pressure level. It's to protect the truck. Diesel isn't just a fuel. It's also a lubricating oil too.
Hey man awesome video, but quick question for you. I got a P0483 code on my 05 cummins as well, says cooling fan speed. I got it while i was hard on the gas, and another time cruising around easy. And I have a Smarty JR in my truck and it will set it back to stock and untill i reprogram then it clears the code. Do you feel this is what i need to do to fix it? Not sure what my egts are bc my gauges arent hooked up yet. But i honestly dont beat the truck. Its my daily driver. Thanks!
You have one or more leaking injectors inhibiting it from getting enough pressure to even TRY injection for start up.
I just changed my fan clutch on my ford ranger. I never changed one before and it wasn't too bad. Mine didn't have an electrical connection at all. I don't understand how it knows when to work and when to turn off without some kind of sensor connected to it. Anyways, it works. Just was wondering if you could tell me how it works without any connections to it?
Wow man thank you so much for the first minute 45 of the video that info helped me so much:) thanks
hey man do you anything about the throttle position sensor on the 2005 cummins? I m getting p2122 p2127
Really like your video I just subscribed to your channel. I have a question I have a 06 ram 3500 and it wont star not even crank I check the codes and it has a p2509 p2503 p0514 p0483 p0581. I replace the batterys the terminals I check the starter relay replace the ignition switch and still nothing. is there a way you can give a clue
Hey any ideas here I have those codes on 03 ram 2500 and I was going fuel but this makes sense I shredded a belt and had belt material around that nut but anyways the truck starts when it's plugged in for 20 minutes could it be both? Or should I look towards fan is there a way to test that ? Like just unplug fan and try to start?
It is a 2003. I see it the most on that model year.
@JKBassFishing You bet.
So, when you replaced the fan did the computer reboot itself and all was well?
Question...on my 05 cummins 5.9.....ok so my wires aren't cut and the clutch is still functioning correctly, my truck threw code P0480 and PO483 the first is fan 1 control circuit the second is fan rationality check....As my bullydog programmer says and the Dodge digital tachometer also....but can I just repair the wires? Or buy just the wires with new plugs/ new pigtail? Any help would be awesome. Thanks
@haoleboy74
my question is this.. My 03 cummins has not be starting at all lately. But no codes. I was told the injectors were bad. Cahnged those. Truck ran great for a week.. Then it went back to no start. the only way to start is with a wiff of starting fluid on the air filter and it will fire everytime. once its been running for awhile it will start up no problem. but let it cool more than 2 hours and your quick starting again. Could it have something to do with the fan? i dont here it
unfortunately for me my truck is at the dodge dealer he has done a partial fuel test on the truck . he says the fuel pressure relief valve is stuck wide open. would this cause the no start condition?
g conway Absolutely. Pressure and compression are EVERYTHING in a diesel motor. Especially when it's cold- low fuel pressure can cause a no start easy.
Do have a wiring diagram for the clutch fan to the truck or pictures the person I bought my 03 5.9 cut the wires so the fan is always running
@briansmobile1 Fan Clutch came in and installed it. Now I am getting another code for the common rail pressure. After troubleshooting and isolating an injector the truck started right up. Thanks for the tip!
Awesome video, thank you for the help. But my truck has other ideas...Replaced the fan, started the truck, it ran but very rough, idled for about ten minutes as I checked to make sure I had no loose wires. Shut off the truck, left it for twenty minutes to let my wife know the good news, started it again, this time ran smooth as a Cummins should and always has, tested the trailer hookup plug (rewired a while back and wanted to use this weekend) everything tested great shut off the truck went inside to change clothes to pick up that wife for lunch, back out to the truck, will turn over and will not start again, back to a P0483 code, help if you can. Easy question I hope is I have a P0483 code should I still get the lift pump hum waiting for the pigtail to go out?
My idler pulley broke and tore the belt and tensioner...replaced it now have p0483 fan clutch...is that just because of the idler pulley going out? Or should I replace it
does that miles screen and code work on the 99 model?
i got p2509 on my 07 dodge 3500 and its say's the ecm/pcm power input signal is intermittent. other people say to put new battery's on what do you think?
Do you have a picture of where the colored wires from the fan are placed in the male connector end? Wires were pulled out and I had to buy a new male end. Thanks.
My 2003 Ram 5.9 get a P0483 DTC and won't start. I also get a P0700 DTC about the transmission. Fan clutch seems dead after wires were ripped off by a broken belt.
I think that both codes can keep the Ram from starting . Is this right?
I got lucky and was able to use a fan clutch wrench to get up in there from the bottom and pulley holder to break it loose wasn't to bad it lot easier with two people.
Thanks!
Hey Brian I'm from Texas is my first dodge cummins I pass power jumping cables from battery and after my 2004 star to show me 5 codes and made a rattle noise one mechanic said is the engine do you think is possible
Does the codes p2509 or po514 have any thing to do with the automatic trans
as for tool you made . that's good thinking on the fly. ppl he knows there other tools hes showin ya a way to do with stuff you got on hand. with out runnin to auto parts store & waste money / time.
On the new fan clutch. I used a round file to take off the edge inside the nut. If you have trouble starting the new clutch, try this.
I fought mine for a couple of hours.
Brian hey I love the videos keep up the good work. im new to dodge . I've done motors /trans/rears in friends an family before but
1st 2004 24v 5.9 Cummins I've owned. I bought at auction with plow damn good deal 1350.00 with 150k on motor. haha stole it.... but it threw codes 0483 0480 0720 0500 2509 ect.. I might have screwed some codes up.. also limp mode. I replaced rear speed sensor and output speed sensor. also realizing fan clutch was from ford.. mechanical .. I guess guys are swapping them out to avoid wire slashing. but I changed it all back codes are gone. also replace all grounds I could and battery terminals. what's your take on them changing to mechanical fan clutches. I would think electric better? any how I cut and extend all wires away from blades /rerouted an shielded. my speed sensor didnt go out yet any suggestions. I'm gonna pull rear again an make sure nothing stick in to it an change fluid. thanks for all your info & sorry so long.
Great video
Hey was just wondering when u had the fan clutch code was ur truck shuttering at idle kind of rough idle? Mine is just wondering what is causing this and if its a bad idea driving with this code.
Random question but do you still have the vin for the truck
Have a 01 dodge ram turbo diesel 2500. i replaced the starter bt it still won't start unless I arc the starter. not sure what to do next. Josey
Kevin why would you patent that? They already make a air impact tool to remove those without messing it all up like that
Very good man! Thanks.
i just changed mine, i just went and bought a fan clutch wrench, took off a few of the fan bolts off of the fan clutch.You will also need to put a bar in there to keep it from slipping. then beat the crap out of the wrench with a hammer.
excellent ...... awesome job ...
That's a code for the transmission. It usually only triggers when a computer goes off line or fails.
I have a 2003 Dodge Ram Cummins that doesn't want to start after sitting replaced fuel pump in tank checked for codes nothing comes up..Once I give a shot of brake kleen it fires..Runs great and all after it sits seems like it loses its prime..Any suggestions...Thanks
@briansmobile1 How do you keep the waterpump from spinning? You don't explain this. It's important, especially with a stuck bolt. info would be ver useful.
do you if theres a way to bypass that fan clutch, so the computer thinks everythings fine
@Osorocks2010 How is your appetite for wasting money?
I just bought the removal tool from my Snap On guy. Not that expensive and worth it not to mention so much easier AND, it re-tightens the hex as well. If you're a self wrencher, why not have the right tool for the job is my moto.
hey i change my fan clutch but still wont run its also showing a code for low votage to the a map sensor will that keep it from running all i did is put new injector in
My fan sensor wires are sliced. Do you have a core fan you could sell me? The plug and section of wires off it is missing. Bought the truck Nottingham running. I'm guessing this is why.
Can u just put a cluch fan in with out that plug on it? Or will the truck not start
DANG good question!
Thanks man. Hey I have an 04 and I thought the first common rail was 2003 model You're sure yours is an 02?
good way to get the clutch fan off is to use a rachet strap around the water pump pulley and which ever other pulley is in clear path to get a good tight squeeze on the pully's easiest if you remove the serp.
Awesome video buddy
It will have problems starting. The first time it will start and after that will be hit and miss.
awesome vid bro
Thank you for the info
I have an 06 2500 5.9 Cummins, when the temp gets below 10 degrees it will not start, all the dash lights come on, I have a block heater and plug it in when it get cold but the truck still will not crank until the temp gets above 10 degrees, I get the p2509 code, could this be the clutch fan or do you have any other thoughts, need help please.
Doc Wilcox Usually that's a leaking injector or injectors. You can remove them and take them to a diesel shop for testing.
I have those codes will this cause a charging issue? to the point where my voltage meter is sitting at 8 and im only running on battery power.
+Chad Archibald ive change the batteries and alternator and cleaned all my connections and grounds
I have this code my truck runs fine how ever the ac gets hot when not moving cause the fans not engaging do I need a new clutch?
p0weraid You may, Your fan isn't getting enough air wash over the condenser based on what you've described. That could be debris like dead birds, straw, you name it behind the condenser, but is likely a bad fan.
@supercannon2 Thats a great Idea!
i have an 04 3500 with code p 2505 but it starts cold fine its when it gets up to temp that if you shut it off dont want to start back up until it cools off any ideas
amantha mcabee srry code 2509
awesome video
