I purchased a 2011 F250 King Ranch today. It has the 6.7L Diesel engine. I purchased it from a private party. As I was driving home, the check engine light came on. I pulled over at the local parts store and he gave me these codes:
P2703-- manifold absolute pressure/mass air flow throttle correlation at idle
P2069-- fuel level sensor B circut intermitent
P206A-- reductant quality sensor circut
I was hoping someone here could give me some insight on these. I feel that I got a good deal on the truck I hope it is not a fortune to fix it now. Any help you would give would be most helpful
Has anything been changed on the truck such as dpf deleted, am air intake or others? That would be where I would start. If the truck is stock than a trip to the dealer would probably be your best bet IMHO.
Thank you for the reply. I am not sure if the owner has deleted the DPF, it does have the stock air filter. I will make an appt with the dealer. Thanks again.
I don't know how familiar you are with the dpf but if you crawl under the truck and look at the exhaust line you will be able to tell. It looks like this
Okay I see. So when you say delete, you mean to actually remove. I thought it may have been related to the computer programming or something. I have heard that the computer can be re-calibrated to achieve better effiency/power. That will be easy to see. Lastly, I apologize for the late information I just remembered that the guy also said that it had NOT recieved the factory update to the computer. Would that have anythign to do with it?
Yes, the PF is actually removed and then a program is installed on the PCM that makes the truck forget it had a DPF for lack of better words. The fact that the truck has not had the pcm update should not be causing your codes.
Could it be that the original owner had deleted the truck, then replaced the parts prior to selling? May be why you're having so many codes at one time....Just my .02¢.
