I took the truck in to the dealer and they pulled a P2121 and P0708 faults. This is a 06' 2500 CTD automatic with less than 4k on the clock. The dealer found nothing wrong (go figure) but I tow all over the country and cant afford to have this act up again. Is there anything I can check to ease my mind before I hit the road again? I have the list of codes, but P0708 isnt on any of the lists I have found searching. Sorry for the n00b question, but some of you have some really good info and tech help. Thanks.

 

I had the p2121 and p0700. I had a dead accelerator pedal. The apps sensor went out. I was able to clear the 2121 code but had to go to Dodge to clear the 0700.

P2121 Pedal Position Sensor 1 Performance / Rationality

My dealer told me the Autos have a lot of ghost codes and that they have been doing TSB's to fix the problem????

 

Thanks for the info.

Out tonight and got the same codes to come up again. Looks like I'll be at the dealer in the morning to hopefully get this straightened out.

 

keep us posted.

 

They are going to replace the PPS, but have to wait until it comes in. Hopefully that will fix it.
