    Actually I went to Advanced Auto and they ran a check for codes.  The codes were P2104 and P2112.  After they checked the codes I had them reset.  Now just need to find what the codes mean and see if they reoccur in the future.

    Thanks!  I did just clean the inside of the throttle body so I'll see how that works before replacing the throttle actuator control.

You have to take it to a shop to have it reset. if it tripped, it means something isn't working right, and that often leads to lower gas mileage if it isn't fixed, costing more money in the long term

    I did some research and found that your codes both sorce back to the electronic throttle control on your engine.



    [P2104-Throttle actuator control system-Forced Idle]

    [P2112-Throttle actuator control system-Stuck Closed]



    Having not examined the vehicle, I'd suggest two things for you:



    First- replace the controller, which is attaced to the throttle body with one from a salvage yard.



    secondly- get some old rags and clean inside the throttle body using carb cleaner.



    with luck, this should clear up your problem.

I have a 2005 Ford expedition and it turns off on the red light a couple of times already and it is scary because most of the times it's only me and my little girl what I can do about this problem


This is a very complicated and known problem with Fords. If you have Check engine light then follow than Diagnosis.
If no Check engine light is present then you have along way to go. Cut off at idle can occur due to Dirty Throttle body, clogged fuel filter. Also Ford has issued a technical service bulletin T S B which is
malfunction from a wire harness.

The check engine light is on everything is ok on


In most later vehicles, that light may stay on for a fixed number (it can be 5-50, we have both) of startups of the engine or many have to be manually reset. The engine can't tell the computer that it has fresh oil but will turn the light on after some finite mileage since the last reset for periodic maintenance items such as your oil change, but some items can't reasonably reset the computer; it has to be told that the oil was changed.
Check your manual to find how to reset that warning light and if you no longer have the manual for your vehicle, you can download a copy of it from the Ford website.

P2104 P2112 P2111 My 2005 Expedition continues to cut off and the engine light comes on. After a few miles the light goes off. Then the problem starts all over again.


The p2104 code was set because the PCM had to set the idle speed, the p2112 was set to indicate that your throttle body was stuck closed. You can try to remove the throttle body and clean it, check to ensure that it opens smoothly, check the TPS connector to ensure that it is plugged in correctly, reset the light and if the problem returns, you will probably have to install a new throttle body assembly. Hope this helps, let me know

Check electronic throttle control


We have been experiencing same faults on a 2005 Expedition,with engine stopping and the message "Check electronic throttle". Ifirst went to AutoZone and they read the codes. They suggested replacing thethrottle sensor, which we did, but car stopped again. We had to replace thebattery in a month and this is the fix. The battery was almost 6 years old andwhen you first start your engine, it sucks too much load and gives these faultsto the computer. It never stopped since then (3 mo already). Sometimes we useto get the message 3 times a day.
