At the dealer yesterday to pick up parts. Talking to service man, he told me that ford has a new flash (as of 11-23-2009) that throughs a code and sets the SES light when your oil/water temp exceeds the limits of recomended temp differancal, this would tell you (and the service tech when they plug in the computer) that your oil cooler is pluged or pluging up, the dealer no longer has to drive your truck to see this and you don't continue to drive your truck not knowing you have a problem until you distroy more parts.

In other words, when the coolant and oil get to that 10 or 15 degree's differance from each other, your SES light comes on and it sets a code, if you get the codes read it will tell you that you oil cooler is plugin up because of temp differance's.

I hope this make sence, i am not good at explaning things like this.


Good Luck!

 

Sounds like an update that makes sense. Hopefully they didn't also de-tune them more. Seems a decent bit of folks report lower power after a new flash gets put in. Could be others reasons though too. Maybe I am just too skeptical.

 

Did you ask them if there were any other changes to the FICM when they did the flash. Sounds like the changes were in the PCM.

 

SO what happens when either the EOT or the ECT sensor is the bad part?

 

I would think that when it throughs a code and the teck plugs in that it would tell them one of the sencors is bad with an ohm's test, and you just saved 2 grand! Hell i don't know! Is that what happened to you?

 

TSB 09-24-3 6.0L DIESEL CALIBRATION UPDATE - VARIOUS ISSUES

Publication Date: November 20, 2009

FORD: 2003-2005 Excursion
2003-2007 F-Super Duty
2004-2010 E-Series


This article supersedes TSB 9-7-11 to update the model years covered and Integrated Diagnostic System (IDS) calibration level.

ISSUE:
Some 2003-2007 F-Super Duty vehicles, 2003-2005 Excursions and 2004-2010 E-Series vehicles, equipped with a 6.0L diesel engine may exhibit hard start, no start, white smoke, lack of power, running rough condition after cold engine start up, or diagnostic trouble codes (DTCs) P0404, P0470, P0611, P1260 and/or P1378 issues. Refer to the Calibration Content for information detailing specific vehicle content by vehicle application and model year that is being addressed by this calibration update.

This article includes previously released calibration content that improves injector performance in cold engine operation and additional diagnostic capabilities and product protection strategy enhancements. These enhancements provide additional diagnostic capabilities, adds additional new DTCs and engine protection strategies. Refer to the Calibration Content for additional details. See the appropriate Powertrain Control/Emissions Diagnostic (PC/ED) manual for technical descriptions and diagnostic routines associated with new DTCs.

ACTION:
Reprogram the powertrain control module (PCM) using IDS release 63.13 and higher or 64.01 and higher. The transmission control module (TCM) and fuel injector control module (FICM) , will automatically update if they are not at the latest calibration level. This new calibration is not included in the VCM 2009.11 DVD. Calibration files may also be obtained at MOTORCRAFT PARTS FOR FORD, LINCOLN OR MERCURY VEHICLES.

CALIBRATION CONTENT

Reprogram the PCM to the latest calibration following Workshop Manual (WSM), Section 418-01.

The PCM and FICM calibration update contains improvement actions to address the following symptoms:

2005 F-Super Duty 6.0L:

False DTC P0470 - Exhaust pressure sensor A circuit fault due to a freezing condition.
False DTC P0404 - Exhaust gas recirculation (EGR) performance due to a stuck turbocharger condition.
Cooling loss protection - Revised engine protection strategy when an engine over-temperature condition is present. Vehicles updated with this service calibration will display higher temperature gauge readings when high engine oil temperature (EOT) conditions or high engine coolant temperature (ECT) are encountered and may disable EGR operation to prevent possible EGR cooler damage.
Oil cooler efficiency monitor - DTC P012F stored and wrench warning lamp illuminated when the oil coolers efficiency drops below a specified threshold for a given speed and vehicle load condition.
Turbocharger vane sweep strategy - Performs a sweep of the turbocharger vanes and unison ring during stationary idle conditions. Vane sweep can occur once per hour to help reduce turbocharger sticking.
FICM low voltage detection monitor - DTC P0560 stored and wrench warning lamp illuminated when PCM vehicle power (VPWR) parameter identifier (PIDS) is below 10.25V for 60 seconds or below 9V for 4 seconds.
Turbocharger over boost detection - DTC P0234 stored and wrench warning lamp illuminated when a turbocharger over boost condition occurs.
2006-2007 F-Super Duty 6.0L:

False DTC P0404 - EGR performance due to a stuck turbocharger condition.
Cooling loss protection - Revised engine protection strategy when an engine over-temperature condition is present. Vehicles updated with this service calibration will display higher temperature gauge readings when high EOT conditions or high ECT are encountered and may disable EGR operation to prevent possible EGR cooler damage.
Oil cooler efficiency monitor - DTC P012F stored and wrench warning lamp illuminated when the oil coolers efficiency drops below a specified threshold for a given speed and vehicle load condition.

and there it is for ya all

 

Damn it, I wish I would have known about this. I took my truck in yesterday to get a new alternator installed and would have asked for the new flash. Crap.... You know what would be great if they can make a TSB to do the same thing for the HPOP.

 

Holy smoke that flash has alot of updates!Hope it helps those that get it.

 

Rep to cheezit, you are a invaluable resource on this site lately man, great stuff!

 

More reps to cheezit. Now i wonder if its worth it for me. I picked up Autoenginiuty and plan to scan about once a month anyways to hopefully catch this early.

 

Thank you cheezit!

 

Damn near everyday I see that difference. On average your EOT and ECT are going to be that far apart. Are you sure it's not when they exceed that difference to a great degree?

Edit: I just saw what was posted about that update and I didn't see specific temps, just if threshold values were exceeded. Anybody have the numbers on that? Otherwise if it's the 10-15 degree range and I have that update, I'll have that wrench on all the time.

 

If I had to guess I'd say they'd set up the new DTC to trigger when the oil temp is GREATER than the coolant temp by 15 degrees or more. Wouldn't that guarantee that the engine is up to operating temp before the little wrench would pop on?

 

I thought I was the only one with a large spread. My oil temps when running HWY are about 70* cooler than the coolant. I spent $20 for a new EOT sensor to see if it's bad. I'll be wrenching soon to see the facts.

Maybe my Oil Guard housing on the frame rail is providing additional cooling??
