2002 4.7 2wd Durango stalling out
 

durango has issues... keeps stalling out...

have had lots of codes, and tried to address them... here is the deal....

p0440 (have not yet replaced purge solenoid or gas cap -- this is reoccuring quite frequently also)
p0441
p0123 (right after i changed the tps - reset, never came back again)
p0068 WILL NOT GO AWAY, ITS ON AGAIN, RIGHT NOW
p0339 CURRENTLY ON WITH ABOVE RIGHT NOW

i have changed out several parts. master tech here (leonard) has also looked into it, and said the wires were ok per continuity

here is what i have done (everything i have ever touched on the D)

• bank 1, sensor 2 - O2 sensor 7/08 (p0036 long before the p0068)
• upper balljoints 11/08
• lower balljoints 11/08
• battery 11/08
• throttle position sensor 2/09
• camshaft position sensor 3/09
• crankshaft position sensor 3/09
• transmission mount 3/09
• map sensor 3/09
• powertrain control module 4/09

previous to problem, not sure of dates -- most likely unrelated
• 3rd row seat
• air filter
• spark plugs
• a/c condenser
• bulb in 3rd brake light
• stop lamp bulb
• headlight bulb


wife says her brother in law saw thick black smoke leaving our garage the other day, just a puff or 2, after truck had been sitting all night

wife says engine stalls out when oil pressure guage moves to the hot mark.... don't know if this is related or not.... but this is when it stalls -- she said it never used to move at all when running, just in the middle, before the p0068 started occurring

stalls out on long drives, usually 60 miles or more, has stalled out in short city driving, but not as much

she says her oil temp gauge never used to move, ever, before we started having issues with the p0068

she runs royal purple synthetic oil, durango has 115k on it

gets routine oil changes, and scheduled other fluid changes

it was placed on a drb3 scanner and nothing showed other than the codes

I need to fix my wife's truck before i ship off to basic training. please help!

0068 code is the Map sensor and the other is the 0339 crank position sensor. Seems like a lot of sensor issues. Ever have a coolant bathe under the hood from a busted hose or something?

Your list says they were replaced. Have them done again and this time make them do it for free. The issues are still there.

up until now, i have done all this work.... issue keeps coming back.... we took it to dodge for diagnosis, they recommended everything i did.. they did do the map..... and said well, we did the map, should be good..... same codes came back, same issue.... wasnt fixed..... we need to get it fixed.... wont take it back to the same dealer as it is too far away.....

Wow, that's alot of sensors. Even with replacements, the codes still exist. Have you reset the computer to see if it clears some of these codes? If they reappear, I would recommend check the wiring harness going into and out of the pcm. Make sure no connection is frayed, corroded, etc. Must be tight, sealed from the external elements.

computer has been reset, and codes come back, even after part replaced..... wiring was checked @ the dodge dealership and was found to be ok..... did have a 2.5 voltage reading of the 5 v supply circuit, thus wht the PCM replaced...... code has come back again.....

P0068 MAP/MAF-Throttle Pos Correlation
P0123 Throttle Pos Sens Voltage Hi
P0339 Crank Pos Sens Circ Interm
P0440 Evap Sys Perf
P0441 Evap Purge Flow Monitor

Black smoke is unburned fuel.


This sounds like a Central Timer Module. It must be flashed at the dealer.

we have had the vehicle to the dealer, it was put on the drb3 scanner, they flashed the computer...... issues returned..... computer replaced, issues returned again

im a mechanic 3rd year apprentice in canada ill try to help the best i can but i need some information..... how does it stall?? is it comming to a stop and the rpm's just drop..... i need to know what the engine is doing as it stalls and give me more information on your oil pressure gauge its not a temperature gauge its a pressure gauge when it goes in the red is bad but the most common this is a oil pressure sensor being faulty... lets not worry about the "black smoke" just yet tell me about your stalling

CTM does not equal the PCM. If you replaced the PCM and as Hydra suggested it is the CTM, you could still have the issues. I haven't heard of the CTM causing that sort of stuff but contrary to popular belief (in my own head) I don't know it all. Could be! Doesn't hurt to find out from the dealer since everything else has been tried.

IndyDurango

just driving along.... engine turns off..... sometimes wont restart..... if it does restart p0068 is present, and it wont hold an idle for crap..... next day, it will be fine like nothing ever happened, fine for a week of city driving, then take a trip, bam... does it again, stalls out while driving, no warning no nothing, turns off, wont restart

what are the conditions? do you have msn messenger?? if so let me know ill add you it will make it easy for me to get what the vehicle is doing

get a compression test done on all cylinders it should be in the neighbourhood of 120psi. i just re-read your post and the correlation code could be caused by vaccum leaks. engine mechanicle problems and a plugged/restricted exhaust, get to the basics as for the stalling have you replaced the iac? but from what you descride it doesnt sound like thats your problem......... only if it was stalling when you came to a stop........... next time it stalls when you try to restart the durango and it keeps cranking press the gas peddle straight to the floor and hold it there till it starts...... if this helps i would replace the idle air control valve, but the correlation code is a good one..... and you say that the map sensor was replaced correct? how about the o-ring that seals it? faulty wiring at the map sensor connector? if i were you i would make sure that o-ring is there and its not craked or damaged something as simple as a broken o-ring can cause a world of problems!!!! also the plug in at the tps sensor, make sure its not loose move the throttle open and closed make sure it closes by itself smoothly

the map sensor was the only thing i didnt do myself, the tps i did and all was good.... the dealership as a last resort did the map sensor.....

car is actually with my wife, im not where she is at....


i and a dodge mechanic looked over the vacumm lines, found no obvious issues... supposedly it was done as well in their diagnostic where they found nothing, other than replace everything related to the correlation code....

sometimes it would die @ a stop, liek after a freeway crusie.... come to the offroamp, stop, and it would not want to idle for beens, sometimes would stall out... then pop a crankshaft intermittent or the correlation code

i have not yet tried spraying starting fluid in the engine bay while running to see if that changes the idle.... i will be using a sprayer that will atomize the mist spray

i do have msn, but am about to head to pepboys right now for a battery on my sisters car

If you look into the schematics like I did you see the correlation between the CTM and PCM.

CTM is not the computer.


First off I hate the dealer...... Second off they're idiots...... Third off it makes perfect sense.

Sounds like crank position sensor to me still.

hydrashocker, i am not trying to discredit what you said, jsut merely stating what i have done. -- you said the ctm can be reflashed? what about just replacing it? i don't want to spend the $ but it needs to get fixed.... just don't want to spend the $ to have the dealership flash it, if that $ can be put towards a new ctm.....

trying to arm myself with everything i can before my wife throws any more $ at her truck.... no matter that i am trying to help her out and save her $, it's my fault she is wasting $ on stuff that doesn't fix it..... it's my fault... although it isn't... i know she is just pissed @ this point though, but still....

i replaced the crank position sensor and the code came back, again

hydrashocker, is the ctm a part i can remove, and take to the dealership lose? or does it need to go connected and in the car? what about replacement? if i were to replace it, try to find new? or would that be through a place liek all computer resources, or other?

if its going to be the ctm check this link

https://dodgeforum.com/forum/2nd-gen...knowledge.html

our durango doesnt exhibit wierd wipers or failing headlights and the keyless entry has always worked... so i have no idea...... i just want this dang truck fixed.....

The CTM is located behind the drivers side kick panel. This module is like a PCM and can have random problems. Yes the windshield wipers arn't acting up but it has engine and PCM inputs. Now you have to get another one and have it flashed to your truck. You just can't reflash it.

If you are SURE it's not a harness issue then go to it. CHeck and make sure there is no water in any of the connections on the harness of the CTM and it's not wet. Windshield replacement has been connected to leaking water onto the CTM.

The problem with the oil light and temp thing mixed with problems with the PCM voltage and strange things like that point me to the CTM. I looked into the correlation between the PCM and CTM and they are wired together.

This is just my opinion.

from what i was reading online, there a re 2 versions, the crap version and the high end version that has keyless entry and a bunch of other stuff.... we dont have an alarm, but have a peanut shaped key fob for keyless entry... i guess i need the better one....

can i remove this part from a donor truck and take it to a dealer and have it reflashed? or does it need to be mounted in our truck? i am just worried, i spend another $200 and it still doesn't fix the problem.....

are you mormon?

if your getting a corelation code i dont think its the ctm the ctm is doing what its supposed to do when it sees the corelation code it will shut the engine off to prevent damage check your wiring at the tps and at the map sensor and your grounds check the wiring staraight back to the pcm check it for continuity and resistance high resistance causes problems

no one ever said anything about the ctm shutting down the engine.... only thing we ever heard was bad pcm.... no one has even ever looked into the ctm being an issue.....

the wires were checked with a dvom, thats why the dealership said pcm, given the history of all the sensors i replaced and the codes kept coming back.....

ugh.... this is jsut as frustrating as dodge saying oh we fixed it, there is nothing wrong, it's a bad pcm.....




glad i don't have to deal with any of that crap on my 85 toyota

^ LMFAO ^

Oh hell no I'm a drinkin, party hungry, lady smackin, hard nosed Slayer lessoning metal head!.......:D

Again the correlation between the oil light and temp with the engine issues??????????

Check this out, theres some good info. A link and PDF:

how sure are you its the ctm? and is it a part i can just get and take it in my hand to the dealership? or do they need to do it in the vehicle? should they try to flash the current one first?

when we had an issue with an 00 dakota, we had a cel and a p0601, it was recommended to have the dealer just flash it, instead of replace the pcm... well it worked... the flash made it go away

I don't think it's the CTM but hell you have replaced all else. Again, my bet was on a previously replaced part.

BTW, CTM will run you $490, dealer only install, D is required to be there (LOL) and take both key fobs with you if you are going to try that.

IndyD

screw the dealer installing it, or buying it from them..... supposeldy, everything is dealer only.... i just replaced the pcm, with one from all computer resources now with a lifetime warranty for $199, and i installed it myself, no dealer involvement whatsoever.....

honestly, i think dealerships are a scam, i was given free help from this site, that was exactly what the dealer said... they went down the list, just like i did to try to nail the code..... when we said i replaced this , they went to the next sensor.....

UGH!!!!!!

Again, I am not on the CTM bandwagon. However knowing you what to do the install yourself... Great! When can I come over to use your $10,000 DRB tool to program the CTM? And the untold cost to learn how to use all the programs?

I hate the dealer too however reality comes into play sometimes.

Not typing for my health... Dealer only install.

IndyD

drb scanners are only 4k, and i dont have one, but i can take stuff to a friend that is semi local that is willing to help out.. that's why it would be better to not have the vehicle.... its not really driveable at this point.... cuts off, and wont restart...... restarts whenever the hell it feels like it.... honestly, it isnt safe to drive on any open road..... and i cant just tow the damn thing everywhere.....

again...
classic symptoms of a failed CRANK POSITION SENSOR.

See post #3 4 pages ago, post #17 yesterday. Or don't. Just because it has been replaced before at home doesn't mean it was right or that the sensor was good or that something else didn't ruin it again.

I'll trade you a 1997 Explorer straight up for your troubled and demented Durango. The Explorer is guaranteed to run and start 1st time.

IndyD

it isnt my vehicle it is my wife's she needs it to run... part was replaced with a new oem part, codes reset, and it came back.. wires were checked for continuity, and resistance, and came back good..

is there a procedure for actually checking the crankcase sensor? i will check the old one, and new one for specification... really doubt that is it though....

Camshaft senor?

replaced the camshaft sensor with a new oem one

why would it be the cam sensor your getting a map tps correlation code and the ctm see's this and it commands then engine off...... the truck does not stall it is actually being turned off by the ctm when it sees the correlation code

it was one of the sensors listed in the factory diagnostic fix pdf i had, that i can no longer find

key word is diagnosis you need to properly diagnose this problem not just ask people on the internet and never mind the dealer thay will just keep shooting parts at it cause they dont care. take it to a local shop where a technician i say technician because we are not mechanics we are automotive service technicians mechanics are in the backyard!!!! calling us mechanics is rude
