Right now things just got worse..

the only thing i want to do with my CR is sell the **** thing already, I have had it with it.. NOw i get it back from the shop and im throwing codes left and right from this thing..

P0217 coolant temps high
P0480 cooling fan 1 control circuit open (low speed fan relay)
P0483 Cooling fan speed
P0541 Intake air heater relay one low
P1749 TTVA position sensor circuit low
P1754 TTVA stuck

Long story short here is what happened, i took the truck in for help with fixing my apps sensor codes (P2122 and P2121) GRANTED they were fixed, somehow replacing this fan clutch cleared and solved these **** codes, and the truck was throwing nothing else. At the same time, it went in for a fluid change in the T case, diffs, and trans flush and fill. I had NO CODES whatsoever in regards to anything else other than 2122 2121 0483 and 0541.

NOw i get the truck back today, drive it home, it shifts erratically,and check engine light comes right on... It would toss second gear at 2400 rpms or so, and at times even skip third and fourth gears, and it even overheated on me as well. idle came up to 1000 rpms or so, Caused the engine alarm for overheating to come on while i pulled into a store parking lot, and cooled off for a bit. Cycling the key and prior research led me to believe just that the TV motor TTVA or whats it called is outta whack on this truck. so i let it be, but now the overheating i couldnt explain, so i cycled the key again, and got the above codes mentioned.

far as the overheating issues go, well the fan clutch would come on, but it would spin the same way with the AC on or off, truck at normal, cold, and hot temperatures. I could stop it with my hand. I could hear the motor "click" as if the fan wanted to come on and it never did, i felt no resistance out of it, nor any ways for it to come on. I have cleaned the connections, i have checked the wires, and they seem good, they are tucked away behind the little steel protector, and yes this fan clutch is NEW... so it has me pretty ticked off...

I also unplugged and replugged the TTVA motor, cleaned the connections, left the key forward for a minute, and still get the codes on teh dash, only difference is no check engine light comes on now, but truck drives the same, will rev up, and will shift when i left off the throttle.

all things point at me needing a TTVA motor, possibly another fan clutch, and hopefully not, the ECM

Is there anyway to tell if the ECM is bad or not, ive lost my dodge dealership in LDO, and have no way to go out of town right now, i cannt drive the truck either it seems.

Ive priced the parts, but the **** things are expensive, and really im tired of replacing them

in regards to that, i have no clue what FC my mechanic put in the truck, so is it possible that if its of something other than OEM that it would die this quickly or go bad this quickly?

I NEED HELP! and patience for this thing, im even considering a duramax or even a ford now.. this is getting ridiculous!

thanks for readin my rant and for your help

Rick

 

bummmmmmmmmmmppp

 

i think you have a short to ground in the 5 volt supply. the most likely place is by the ac compressor. the wiring harness was shipped out with out wire loom on about 6 inches of it at the compressor. tape the wire back up and install the loom. there is one other less likely problem with a ground. look under the truck engine there is a ground strap to the cab. the end attached to the cab will corrode and not make good contact

 

See this thread.

Hopfully the pic will be there.

 

thanks for the help fellas

cant see the pic tho, so i have no clue whats up... ill read up on it tho

 

I've tried to repost the picture here, but it won't let me saying I've already uploaded the picture to this thread. As you saw its not in the link.

I have a copy of it. Send email to CoastalDav@Bellsouth.Net and I'll forward it to you.

just thinkin out loud here

does the plug that connects to the fan clutch have five or six prongs? IIRC i see six slots, but only five plugs....

thanks fellas!

 

Check the wires the guys above you are talking about for chaffing. The wires run behind the a/c compressor and under the oil filter to a A/C sensor. They are know to rub and chaff through and cause all sorts of gremlins. The reason they cause all these gremlins is they share the 5 volt circuit with many other vital functions.

 

hey guys how are you

Mr Beek thanks for your help, Dave, and everyone else too, but now, i think im in over my head even more so....

I got home from work and cycled all the previously mentioned codes with no Check Engine Light on, just to see if the FC would work, that was my main concern at the time, NO Check engine light came on and I THINK that the FC was working, i left the truck on and the fan seemed to spin a little harder, but then it slowed and the check engine light came on.. leadin me to think i have a short somewhere... it was still rainin outside, hence time for more research....



OK then weather has cleared up and im happy again

and i went outside and took advantage of checking the grounds on the truck. I checked several of them, and took wireloom and tape to the most problematic ones.

First one that i attacked was the one by the passenger side by the AC compressor, From reading, it was notorious for causing problems with the trucks due to it being connected to many of the functions that i was having problems with. Low and behold, it was worn out, the tape was falling off as was the cloth like material around it, YET i saw no signs of it worn to the bottom or bare wire anywhere on it, I loomed two connections, one towards the right fender towards some sensor, and the one that connects right away to what i think is the AC clutch motor? i dont know, its a simple two prong connection right next to the one that heads towards the sensor on the right. No signs of wear on either one,

Next i went up to the batteries and checked them both. To my surprise, i had a bare ground wire right up on the drivers side battery, I taped it, loomed it, and retaped it again just to be on the safe side.

Next i went to the passenger side battery and checked the cable on the positive that goes to the alternator for a short, nothing, i did not see anything that resembled bare wire, or chaffing for that matter.

I also checked the battery cable where it passes by the pipe that hooks to the airbox for chaffing or damage signs, i saw none, and also loomed and taped it up for good measure.

three spots down to look for shorts and one more obvious one to check. I went to check the negative battery terminal on the drivers side battery, and it was corroded a bit, and well rusted out, i did not try to clean that one out due to running out of daylight, but i do see that it could use some attention, and will go back to it...

I went back and decided to drive the truck around for a bit at slow speeds, before i did that i went and cycled codes again.. and got the same codes

P0217
P0480
P0483
P0541
P1749
P1754

and GUESS WHAT DECIDED TO COME BACK AND screw with my day again... i was not happy at all seeing these two ****** come back into play...

P2121
P2122

This point in time i was thinking that i want to light this truck on fire, and really get rid of it... But on the positive end, the AC seemed to cool more, the truck didnt overheat (then again its only 81 degrees and drive was no more than a couple of miles) which led me to believe the fan clutch was working.. BUT i did have the dead pedal BS occur to me again on at least five or six occasions ***????? SERIOUSLY!!!! id press on it, and it wouldnt go, let it go press again, and there it would go, or press it hold it and the power would surge all of a sudden.. UGH!!! this thing was makin me mad... I still dont know if the FC works, i still get the **** apps pedal issues, and i still have the P1749 and P1754 codes on the truck as well!! the truck stumbles once in a while too and slightly misses, something it didnt do before, until now that i tried to fix the grounds to the best of my abilities... I did get the truck to operating temperature tho, and reset the computer for the mile counter, and it was working erratically, it started at 0.1 mpg and worked its way to about 7.8 mpg when the trip was done, it did this very very slowly tho, i did also park the truck in the driveway at operating temperature, and cranked ac to maximum to see if it would overheat, no such luck after a few minutes, i did open the hood to see the fan spin, and it would speed up just lightly, but not whirr hard, and it seemed to blow hot air back to the motor, AC in the truck was cool tho, and the compressor would kick on frequently IE every 30-45 seconds or so... but it was working great....oh and based on the TTV motor, truck was shifting well, it didnt toss any gears late or anything, infact it gently shifted into the gears, but on one or two occasions, it did skip second all together, I did not drive the truck hard tho at all

Thus i have no clue with this...

My next question is simple. WHAT DO I DO NEXT????? DO i need to clear these codes and re run the truck now that i have checked the grounds? is the computer telling the truck to screw with me cause it thinks i have not solved any problems? Shouldnt the problem reset itself once i fix or try to fix something? IE the grounds i checked?

OR do i need to just unplug the batteries for a couple of days or so, and get back to the truck on monday, monday is when i can get a computer and a TV motor here, which is my next approach, a TV motor, then clear codes and see what it does.. from there if it still shows open circuit codes, or a short, off to my electrical guy see what he can do... (that is the plan, because i dont have faith in fixin this thing anymore)

on another note, is there a way I CAN clear the codes without a code reader, scanner or computer?

seriously, i feel with this CR, its one step forward and three steps back, what i went to solve, came back, and with more problems than i can honestly bear handling.. I want to have this truck back and WITHOUT any of the above codes, the only ones i can live with are the P0541 and P0483, seein as they were harmless before...

but still, the more i mess with this truck and try to learn, the more i realize that the 12valves were and are the best trucks dodge made, this electronic cummins mumbo jumbo is just not worth it...

I just wanna fix it and be done with it..

any ideas, suggestions, help, or direction will be truly appreciated... thank you all very much for your time, efforts, help and reading this rant...

Respectfully

Rick

 

BUMP??

anyone have any ideas whatsoever?

Please

Rick

 

BUMP Again

happy fourth of july, got a ttva motor today, and will load test batteries and install ttva motor tomorrow, everything is closed today..

anyone have any ideas?

 

Ok. I re-read your list of problems. I had a problem with my 06 shifting crappy. I took it to a mechanic to see if it was throwing codes. The mech. could not get into the computer. Took it to another mech who used snap-on device, and could not get into the computer. Took it to DC dealership, they said that there was a problem with ECU, it lost the vin code. RE-flashed it ($100bux) and it has been fine since.

Get a buddy with a scanner to see if he can access the ECU, if not may need re-flash. OH, and my mpg got better, and tranny shifts better.. not great, but better.

 

lost the dealership in laredo friend..

so im outta luck on that here.... as we speak im headed out to load test the batteries, drop off the ttva motor, and clear the codes on this thing...

i know he has a high dollar code scanner, ill ask if he can get into the ecm.. good call

thanks!

ill report later...

 

just got back from doing some of the required

I took my batteries back to NAPA, Napa GOLD or legend or whatever they are called. From Sept 09, and they both tested excellently. No problems on either battery, both good, so that takes care of the issues on the batteries.

terminals and posts have been cleaned, TTVA motor is to be installed, and initialized, and the codes will be cleared, so lets see what happens next..

 

hope it goes well my friend
