ETC - electronic throttle control problem .
P0606 - Powertrain Control Module (PCM) Internal Communication Error
Description:
P0606 indicates a register readback (PCM internal communications) error.
Possible Causes:
Diagnostic Aids:
Internal PCM failure. Install a new PCM.
For Electronic Throttle Control applications, an internal PCM failure, or an ETC system FMEM condition exists. Repairing the other DTCs can fix the P0606.
Application
Key On Engine Off
Key On Engine Running
Continuous Memory
Vehicles With Electronic Throttle Control (ETC)
The DTC is an indication of a failure mode in the electronic throttle control system, which includes the accelerator pedal position (APP) sensor, electronic throttle body (ETB), and powertrain control module (PCM). It is accompanied by other DTCs which provide repair direction. Diagnose and repair those DTCS, and the P0606 will not be reset.
All others
Make sure to check for aftermarket performance products before installing a new powertrain control module (PCM). If it is necessary to install a new PCM, refer to Section 2, Flash Electrically Erasable Programmable Read Only Memory (EEPROM).
P2106 - Throttle Actuator Control (TAC) System - Forced Limited Power
Description: The TAC system is in the failure mode effects management (FMEM) mode of forced limited power. This DTC indicates the FMEM action is in effect due to a failure in an electronic throttle control (ETC) related component or module.
Possible Causes: Unplugged motor, circuits shorted to power.
TAC motor open, unplugged motor, circuits shorted to power.
TAC motor stuck open or closed.
Mass air flow (MAF) sensor fault.
Throttle position (TP) sensor fault.
Module communications network concerns.
Manifold absolute pressure (MAP) sensor fault (Vehicles with an EGR system module [ESM]).
Output shaft speed (OSS) sensor fault (Crown Victoria, Expedition, Explorer, F-150 4.6L and 5.4L, Grand Marquis, LS, Mountaineer, Mustang 4.6L automatic, Thunderbird, Town Car).
Turbine shaft speed (TSS) sensor fault (Crown Victoria, Expedition, Explorer, F-150 4.6L and 5.4L, Grand Marquis, LS, Mountaineer, Mustang 4.6L automatic, Thunderbird, Town Car).
Anti-lock brake system (ABS) fault (Crown Victoria, Expedition, Explorer, F-150 4.6L and 5.4L, Grand Marquis, LS, Mountaineer, Mustang 4.6L automatic, Thunderbird, Town Car).
Diagnostic Aids: This DTC is an informational DTC and can be set in combination with a number of other DTCs which are causing the FMEM. Diagnose any accompanying powertrain DTCs first. For Crown Victoria, Expedition, Explorer, F-150 4.6L and 5.4L, Grand Marquis, LS, Mustang 4.6L automatic, Thunderbird, and Town Car with only P2106, repair any ABS DTCs, ABS related DTCs in other modules or vehicle communication concerns using the appropriate section of the Workshop Manual.

Do a manual oil pressure test with an oil pressure tester you should have no less than 20 Lbs oil pressure at any time good is 40+ anything less than 20 and noisy engine is bad

Sounds to me like the mass airflow meter, cutting in and out. When faulty it can completely shut a car off, and also ingauge limp mode. I hope this helps. Let me know how you get on.

I have hearing a lot of this lately with Fords. Most of the time this dash board light comes on due to problems with the Throttle Body (TB)not just your coolant,etc.. If it is sticking,dirty,causing misfires,etc. then this can cause an engine fail safe mode.You might first try putting in some injector cleaner and a higher grade of gas.Many people I know who have had this problem have had to have their TB cleaned and/or replaced. This is something Ford dealerships now about,but hasn't been made a recall or anything.There are service bulletins though.Mainly keeping cleaner in your gas and performing ritual tune-ups/oil changes may be the only thing you can do.Hope this helps

have the oil pressure checked, asap, at a service center to make sure the oil pump is not going bad. i would also take into consideration the suggestion offered by fixcar001. i would also refrain from driving until you've made sure i's not just a monitoring problem.

Hi,
First of all I would like to start with this bit of information for you. Most scan tools will not pick up fault codes on a 7.3L diesel. I keep an Actron pocket code reader with me at work to diagnose the gas engines, but when it comes to the diesels I have to use the Ford IDS system to get fault codes. I can't explain why, but thats just how it is.
Now on to your problem........... Without fault codes to go by, I am going to make an educated guess as to what is happening to your engine based on the most common concerns I see with these engines. My guess (based on your description of the concern) would be that one of the fuel injector wiring harnesses located under the left or right valve covers is becoming dislodged. I see this alot and as a matter of fact I just repaired one this past friday.
Since we dont have a fault code to tell us which bank has the bad connection, you will have to remove both valve covers and check where the wiring connects to the valve cover gasket. These connectors, over time, tend to loosen and move away from the valve cover gasket connector causing you to lose up to 4 cylinders, when the engine cools down a bit they regain the connection and work fine. The connectors don't have to move much either for this to happen.
You can go to Ford and buy a new under the valve cover harness for $$$ or you can simply install a plastic wire tie to keep the connector in place. The choice is yours. I would also like to add that if you do this job yourself you will have to remove the big intake hoses that go from your intercooler to the engine. It is critical that you clean the ends of these tubes to remove any oil residue before reinstalling them. You also want to torque the tube clamps to 18 ft lbs when you reinstall. Tighter is not better, they will blow off under pressure.
I also want to add that your truck was involved in a recall (07S57) for the camshaft position sensor. If it hasn't been replaced yet call your Ford dealer with your vin number and ask about it. When this cmp sensor goes bad it will shut the engine off leaving you stranded.
I hope some or all of this helps you!
