CEL on again......

[Rwalker]

well, i made a trip to the mountains today, and guess what, a mile from home my CEL came on again. Seems like everytime i go to the hills i get a light. Dont know if it because i cant rev it up real high or what, also, i added some Diesel Kleen to this tank, that always seems to be a factor too. Not sure what to do now. I am really getting tired of these lights coming on. Any idea on where i can go to have it downloaded other than the dealership. I always feel like i am not getting the whole story with the dealer ya know. Anyway, i will post again when i find out what the deal is with the light.

went to the local Checker auto and used their downloader, came up with a P1331 code, said it was a manufacture specific code. ANy idea on what this code might be. I have had it before and it ended up being a turbo, but then again my service advisor was a total idiot, never told me what the actual code meant. Any info would be great. thanks.

Hmm, that's a good one, I can't find it on any list i have. BTW any code below the number 1000 are generic emisson codes, anything above 1000 is manufacturer specific.

ahhhh, yeah i looked online to see if i could find a description for the code but nothing. I had it cleared so il see if it comes back, maybe it was a fluke or something.

Well, another day gone and no CEL. I hope this is a goo thing. I even drove it a little harder than usual to see if it would trigger the light but nothing. One question, if i get a light, then it is cleared, if there is still an issue then i should get the light again quickly right? Or will it take a while to show up?

Sometimes certain codes have to monitor a fault for a certain number of "drive cycles" before it will kick the MIL on, a good code scanner will show you the pending codes (seen a fault but not enough to set the MIL) and you can see if the problem is still there

[Rwalker]

Cool, so another question, and this may sound dumb but, would my 04' engine and computer be the same as an 03'? If i remember right, the scanner went up to an 03' model. So now i am wondering if it even read the code right.

[fordnut85]

it may not be the EXACT same motor and programing but it uses the same j1850 interface

[Rwalker]

So chances are that it is reading correctly? I hope so. im still gonna take it into the service dept. to have it checked.

I have a friend that had the same problem, one of the codes barometric, and two other that i don't remember right now, any way he took his 05 6.0 to the dealership and got a new download. and has no problems since 1 year and counting
