Ford just came out with a TSB today 12-6-4 to reprogram the PCM/TCM to latest level, installed a deflector shield on the intercooler and possibly replace the drivers side catalytic convertor if needed.

FORD:
2011-2012 F-150

ISSUE:

Some 2011-2012 F-150 vehicles built on or before 5/24/2012 and equipped with a 3.5L gasoline turbocharged direct injection (GTDI) Ecoboost engine exhibit a steady or flashing malfunction indicator lamp (MIL) with various diagnostic trouble codes (DTC) and drivability concerns.
ACTION:

Follow the Service Procedure steps to correct the condition.
SERVICE PROCEDURE



The calibration update contains improvement actions and enhancements to address the following conditions:

• Intermittent stumble and/or misfire on hard acceleration after an extended drive at highway speeds being more noticeable during humid or damp conditions.
• Intermittent engine surge during moderate to light loads at cruise.
• Powertrain control module (PCM) Misfire DTC P030x.
• PCM DTC P0430 and/or P0299.

NOTE:INSURE ALL HARD FAULT POWERTRAIN DTCS ARE ADDRESSED PRIOR TO PERFORMING THE CALIBRATION UPDATE.

1. Check for DTC P0430. Is DTC P0430 present?
   1. Yes - Replace the left bank catalytic converter assembly. Refer to Workshop Manual (WSM), Section 309-00. Proceed to Step 2.
   2. No - Proceed to Step 2.
2. Is the Charge Air Cooler (CAC) equipped with an air deflector plate? (Figure 1A)
   
   
   Figure 1 - Article 12-6-4
   1. Yes - Proceed to Step 4.
   2. No - Proceed to Step 3.
3. Install CAC air deflector plate with two new push pins. (Figure 1B) Proceed to step 4.
4. Reprogram the PCM to the latest calibration using IDS release 79.02A or higher. This new calibration is not included in the 2012.5 DVD. Calibration files may also be obtained at www.motorcraft.com.
   NOTE:PLEASE ADVISE THE CUSTOMER THAT THIS VEHICLE IS EQUIPPED WITH AN ADAPTIVE TRANSMISSION SHIFT STRATEGY WHICH ALLOWS THE VEHICLE'S COMPUTER TO LEARN THE TRANSMISSION'S UNIQUE PARAMETERS AND IMPROVE SHIFT QUALITY. WHEN THE ADAPTIVE STRATEGY IS RESET, THE COMPUTER WILL BEGIN A RE-LEARNING PROCESS. THIS RE-LEARNING PROCESS MAY RESULT IN FIRMER THAN NORMAL UPSHIFTS AND DOWNSHIFTS FOR SEVERAL DAYS.

Thats great news! Does/did your truck have the issue and did you get the latest update? Fortunately, Im one of the lucky ones without that isse.

 

Trying to envision where the deflector plate would go..

 

I did not have the issue. I just work at a Ford dealer and wanted to let everyone know. The eastern part of Washington state I live in is like a desert.

 

Awesome news. Now hopefully it works and I still have to convince my service guy that I have it.

 

can you post the pic of "figure 1A" please

 

Not excited about the fix being a deflector plate to be honest with you

 

Looks like a pcm update too.

 

My service guy told me the root cause is that the IC is too efficient. If that is the case, a deflector shield will definitely reduce its efficiency hence reducing or hopefully eliminating the condensation build up. It might not be fancy or pretty but from an engineering standpoint, it should work. Hopefully there aren't other underlying causes as well.

 

Doesn't make me tingle with excitement. Get it done and see what happens I guess
