Hello guys we just bought another truck for our business.
2004 forf-250 6.0 L
I know whats going on with 6.0 issues, I had in the near past.
We bought this truck a couple of days ago and I have been told EGR WAS deleted or removed (not verified yet phisically - because I do not know how to do it, I can't see it.)
1) if you can tell me how to check that I will appreciate it.

2) But here is the problem we have, First of all... code P0013 and we do not know what excatly need to do.

3) and EOT IS GOING OVER FWT until 10 degrees even IDLE... If egr was deleted what would be the reason of that?...
Can be related to P0013?

I can't find a listing for PO 013 fault code on a 6.0L truck. Does it say what the code is for?

EOT normally runs a bit higher than ECT when truck is at operating temp. The EOT can read 5-10 degrees above ECT. If it hits 15 degrees above ECT is when you need to start looking at oil cooler clogging issues. You really want to be cruising down the flat highway at steady throttle for a few miles unloaded and see what the deltas are between EOT / ECT. Mine will read say 188ECT / 191EOT in cooler weather, and 193ECT / 200EOT in warmer weather.

Your egr if deleted should not effect ECT / EOT deltas if everything else is in good working order.

You can check the 6.0L bible here...http://www.backglass.org/duncan/ps60_manual/ps60_019.jpg
for a picture of the egr cooler on the top image and see if yours is there or not by looking down at the passenger side intake manifold from the top of the engine, it's very visible, may need a flashlight for a better look.

Harry6.0 according with online info P0013 is about air intake tem circuit or sensor.
Will check 6.0 bibble and see if we can figoure out if egr was deleted

The link I provided in my last post is from the 6.0 bible, the middle part in the top image is the egr cooler. Heres a link to the entire 6.0 bible...

And yes, Engine Coolant Temp (ECT) is the same as Fahrenheit Water Temp

I see a PO113 here...http://www.backglass.org/duncan/ps60_manual/ps60_094.jpg
for the intake air temp sensor.

There are 2 intake air temp sensors. http://www.backglass.org/duncan/ps60_manual/ps60_032.jpg

Intake Air Temp (IAT1) sensor is incorporated into the mass airflow sensor, and IAT2 is located in the lower image here...http://www.backglass.org/duncan/ps60_manual/ps60_013.jpg

Make sure both are plugged in and the wiring connectors and harness are ok.

I had my harness go bad at the mass airflow sensor connector many yrs ago, caused truck to belch black smoke from overfueling-under boosting. Ford makes a repair connector for the mass airflow sensor that comes with a pigtail harness already attached to the new connector. I just cut the wires and spliced it in, been fine ever since. You can wiggle the wires next to the mass airflow connector while the engine is running at idle and see if it makes it run better or worse, thats how I found mine when it was acting up.

Yours could be something completely different though. Without going into a disertation on how to test sensors, first check if everything is plugged in and do a gentle wiggle test of the wires near the connectors while the truck is running, you may have a wiring harness or connector fault, or possibly a faulty sensor.

Update we have...
We realize that harness "seems" to be the problem with code PO113 an at some point was actally manipulated before (harness), apparently not good and still not working but we will check it again in detail, and will keep you posted about this issue.

But we are still confuse about the egr.. We notice that egr cooler is still in place but we found the mechanic guy who said he "canceled" egr cooler on this truck.
How?? We do not know !!! All he said was he blocked the egr cooler with a "caps" but he refuses to give more details about how it's supposed to work the truck now..
We do not know if they were using a bypass or something to make it work.
The other weird fact to me it's because they never installed a tune on this truck.

We want to use this truck to pull a heavy loaded trailer and even eot temperature is not going over 200 in city, still often goes over fwt more than 15 even idle.

Another finding is that we flushed the radiador to put a new coolant and we realized that thermostat was removed !!

We are very confused about all this
It makes any sense all this info?? What would you say about all this?

EGR cooler can be capped off on the exhaust up pipe side or both ends and be installed to look like it's still legal.

Easy way to tell is just remove the egr valve and crank it over and see if exhaust belches out the EGR valve hole. If nothing comes out, it's blocked off.

If the coolant t-stat has been removed, then the coolant would/should read very low temps on the scangauge, like 160F.

Put a new factory motorcraft t-stat in as soon as possible so you can see what the real engine temps are.

My opinion, you got a used truck that the previous owner is hiding some truths about the engines overall health.

Hope this turns out ok.
