2001 F350 service engine light while towing

[schemi]

I just got back from a trip to Washington. On some of the longer grades i would get a service engine light. The light would turn off about ten minutes later. There was never a lack of power and it always turned off by itself. What could my problem be? I don't have the time right to have it checked out.

Do you have a chip?

When doe it come on, WOT, just pulling up hill, or randomly?

[schemi]

no chip. stock except for 4" muffled exhaust. It came on 5 times i believe. It came on when I started going up the grade. It was only on the steeper grades. For the most part there was no WOT. The only time I may have gone to WOT was merging on to the freeway or passing but there was no light. I also did not have problems going over a pass where the speed limit is 55 and there are steeper grades than I-5.

probably a P1211 code. caused by a weak High pressure oil pump feeding the injectors. might be something related to the IPR or ICP sensor also.

could be something totally different. But, thats what my first thought was when you said it came on, then went off. need to get a good scanner and pull codes to make sure.

wouldn't that cause loss of power? I have no shortage of power. I could have accelerated up any of the hills with ease.

[HVAC SuperTech]

not necessarily. you could just be having slightly weak pump causing it to pull the code.

Mine had a decent HPOP in it, and it would not seem to lose power, but still cause the code.

like I said, its speculation. you would really need to pull codes.

[schemi]

So what did you have to do to fix it

[HVAC SuperTech]

well, it would be a new HPOP. IF that was the code.

until you know exactly what the code is, dont spec parts for it.
