well on my way to work at 4 this morning, my cel came on and stayed on. Great, WTF!! So I did the odometer hold key on thing, and I got some strange stuff. here we go. C 543 , 5 44 , = 338 does this make any sense to anybody, It has 16,000 miles on it it's lifted, and I put a K&N drop in, in it. thats it please help any Ideas?

 

I looked, but i can't find it.

Sorry ...

 

Holding the odometer will run the dash self-test.

To get the codes you have to turn the key VERY rapidly off and on three times. I haven't been able to get this to work, but other 6.7L owners have. I've read that you must have the doors shut and parking brake set also. If it doesn't work, you have to remove the key, open and close the door and then try again. Good luck.

If you just recently put in the K&N, check that none of the sensors on the air box became disconnected.

 

Is every 6.7 owner having problems with CEL's?

 

have you done the G30 recall on the O2 sensor? after i did mine the light was always coming on. the dealer ended up replacing the sensors again.

 

thx for the info guys, I did have the G30 done. I will try the key brake door combo. and let you know.

 

well it just says done, and then the engine light starts to flash and that's it?? I don't know what to do.

 

AZ2500,

I've gone through two turbos and many many many O2 sensors. All the updates have been applied and Dodge doesn't know what else to do. Dodge offered a buy back program but I refused due to the fact that I had to pay for my miles it came out to $4000 plus it's (Old truck)MSRP for (New truck)MSRP and my payments would go through the roof on the new truck. I'll just keep this for a couple years and then possibly trade it for something more reliable if no solution is found. Love the truck but....

 

well almost 500 miles later, IT went off. Just like that service manager said it would

 

the 02 recall does not replace the 02 sensors but only replaces the oxygen sensor module on the right frame rail and involves flashing the cummins controler with the latest flash files for the dpf system to help create reliabity in the system. seeing as everyone here is having alot of dtc's in the 6.7 system what kinda codes you getting . to be honest here at the dealership where i am at very few 6.7 check engine lights on but have had more problems with this motor than with any other diesel since i have been here and that has been over 16 years . but also see the others in the shop with the fords and chevys and they are having issues with the new emission system that we all had to put on thanks to uncle sam.. thanks again bush
