Code P245a

The code page lists it as: EGR Cooler Bypass Control Circiut/Open. I was wondering what this meant. Is this the egr control default setting as in when the truck is just started and the egr is not being used, or is this something I need to get checked out. Truck is running normal and I only check codes when I change oil/filter or fuel filter.

Any mods? Alot of people with the egr cooler delete get this code. I have had it a couple of times with just the egr delete. I've just cleared it, and it stays away most of the time. If you don't have any deletes, I think it means something in the cooler needs to be cleaned, and is sooted up. Don't quote me on that, but I think I read something on it somewhere before.

Yea, I think there's something in your egr cooler sooted up now. Not 100% sure though. That code with a cooler delete seems to be more active in cold conditions.

Code Check?

Is there a way to check what codes you've had or they just pop up when something is not right with the system?

Check you codes with the key trick, here's how.
Get in truck, and shut all doors. Without starting it..................
key on
key off
key on
key off
key on and leave on. (Don't Start)
Do it fairly quick.
Look at the odometer. If there are codes it will bring them up like this.
------p245a--------, then it will keep going if there are more.
When it's done, it will do this.-------DONE--------.
If there are none at all it will just say, --------DONE--------.
Be sure and be ready to write them down, and you can check what they are with the sticky thread at the top of this section.
