p2262 lost 1-2 mpg

[lilbum69]

i think there was a post on this but i cant find it any more.....

9-10-2009 i got a p2262 with 12k miles. the dealer gave it the latest flash and now i have lost 1 1/2 to 2 mpg. has any one else had this problem. the dealer said the flash didnt cause this, so iam not sure what to think???

2007. 5 auto quad cab 4x4.

Are you basing your mpg loss on hand calculations or the overhead computer?

 

[lilbum69]

iam loosing it on the overhead and hand calculations, also the engine seems a little more sluggish... ...

Not sure where you are from... ... ... ... If in the north... could be winter fuel.

I feel I have had the same issue. Did exactly what u say. I am now convinced that the programming has something to do with it. Hopefully a diesel tech on here can shed some light on the answer?

 

[lilbum69]

that would be great steve, iam looking forward to it. its not winter fuel i know that... ...

One or more of our TDR member/Dodge-Cummins techs have already stated on more than one occasion that the latest reflashes do not reduce power, performance, or fuel mileage. I don't see any reason they would lie to us.

I had a requested, voluntary reflash done on my truck about three months ago and noticed no changes in driving or economy.

well a thousand miles later after getting the newest flash for p2262 on 9-10-2009, p2262 is back, going to the dealer on monday. wonder what they will do now????

There is now a test that runs with the scanner when the 2262 is present. The result will be one of the following. Update software only,clean turbo,replace turbo or a combination there of.

The shop should verify all the system is working correctly to prevent reoccurance.

Replaced Turbo at 16,000 miles same code as yours

Well, I have not driven my truck for over a month as I have had three Kidney stone operations and still need at least one more scheduled for Dec 7... with that said, I drove my 2007. 5 dually from Nor Cal to South Cal yesterday for a total of around 1100 miles in one day. I have not had time to put the Edge back in since my truck got a new turbo and reflash. The overhead says that I was getting 18-19 miles per gallon. . I never did hand check it as I have two stents in you know where, and when I stopped(often) I had to run to the bathroom. . The truck ran great and with the new turbo, it doesn't buck when you have the exhaust break on and it has full power. . I have my fingers crossed that all will be well from here on out. Turbo went out at !6,000 miles. . truck is only used to pull my various boats as I have other daily drivers. Missed the Edge for the turbo timer as well as the Active Regen indication. The trip was for not as the boat I went to buy had a rotted transom... $160 in fuel and 12 hours on the road... Oh well, the truck has never had a trip like that since I bought it with 9,800 miles on it so I will chalk it up to a day in my truck along with the radio blasting with sat radio...
