Question about 2005 Ford Expedition
I was driving at 60 MPH when the warning signal sounded and the information panel said "electronic throttle control" as I was pulling over, the car engine shut off. No power to the engine after that. Lights worked, but no power came to the engine. What is wrong with it?
We ended up taking the vehicle to a trusted auto repair shop. The codes came up indicating a failed throttle body, most likely in the electronics. After a few more pinpoint tests, the recommendation was to replace the throttle body. The cost for this repair was just under $500. Since there is no aftermarket on this part, Genuine Ford parts were used.

I had the same problem with my 2005 expedition, with the 5.4 motor. The solution for mine was to clean out the throttle body really well with a rag and throttle body cleaner. what was going on was that the throttle plate was sticking and therfore was sending a signal and shutting the engine down or into failsafe. good luck, you can do this at home.

It just happened to me today! I was cruising at 65mph entering I-93 N tunnel in boston and my 05 Expedition just died! I have a 14 - month - old baby inside the truck! THIS IS RIDICULOUS and very scary! We could have gotten into an accident! It started back after 10 mins but the engine light remains on. FORD should address this problem!

This problem has been happening to my 05 expedition on and off for about 5 months now. Today's mishap, has me unfortunately HAVING to take it to the dealership. Stalled, started again and now my alternator light is stuck on. I bought an extended warranty till 100k and it's got about 68k on it now. We'll see what happens...
Does anyone have a solution that completly solved the problem?

Solution: Contact Ford. If there is this type of problem with a throttle causing a vehicle to just stop and not accelerate, it should be recalled to fix the throttle. This is dangerous when a car cannot accelerate. The throttle could jam or something on a major highway or something.

This also happened to me on a 2010 ford f-150

Due to the throttle being fully electronic and not cable driven when the tps sensor faults it doesn't send the required signal to the pcm(Computer) and the pcm then thinks the the vehicle is off already due to no signal being received, therefore shutting off the fuel injection pulse killing the motor. To fix this you need to determine which tps sensor is at fault which can be difficult if it's an intermittent fault.
This is on of the common faults found though main not apply to all vehicles with this issue.
The majority of the time it is the tps. Other components that could cause this also would be the electronic pedal, wiring fault or the pcm itself.

Check electronic throttle control light came on what is the problem??

I too have a 05 Expedition with the throttle light on. I pulled over and turned the car off. When I turned it back on the warning was gone and the car excelerated as normal. I pass over two train tracks on my way to work. I don't want to take a chance. I'm I to understand that replacing this part doesn't fix the problem? Tired of this car, already replaced the engine!

Cuando el problema persite y ya remplasate el tps te quiere desir que hay problemas con el acelerador pedal cableado o la misma pcm

We too have a 2005 Expedition Limited that is doing the same thing, sometimes it goes months between incidents.
One time the check engine light stayed on, Advance Auto told me the code was 'Throttle Control', so probably the TPS sensor. We purchased a new TPS module from the dealer and installed it ourselves (out of warranty). Within a month or so it did it again, and has done so at idle speed many times and as high as 65mph.
Ford really needs to address this issue, its ridiculous.

The On/Off switch
The Resume/Accel switch
The Set/Coast switch
The TCC brake switch
The stop lamp switch
The throttle actuator control (TAC) motor
The vehicle speed sensor
Cruise Control Engaged
The cruise control system will engage and adjust the vehicle speed based on the activation of the following cruise control switches:
The cruise control switches are located on the multifunction/turn signal lever.
The powertrain control module (PCM) monitors the signal circuits of the cruise control switches in order to determine when to capture and maintain the selected vehicle speed. The PCM uses the throttle actuator control (TAC) module motor in order to control the vehicle speed. For further information on the TAC System, refer to Throttle Actuator Control (TAC) System Description in Engine Controls - 4.2 L.
Ignition positive voltage is supplied from the 10 ampere HVAC 1 fuse to the cruise control switch via the ignition 3 voltage circuit. When the normally open cruise control On/Off switch is turned On, the switch closes and the PCM detects a high signal voltage on the cruise control on switch signal circuit. When the normally open Set/Coast switch is pressed, the switch closes and the PCM detects a high signal voltage on the cruise control set/coast switch signal circuit. To engage the cruise control system, turn the On/Off switch On and momentarily press the Set/Coast switch. The PCM will confirm that the cruise control enable criteria has been achieved. The PCM will engage the cruise control system and record the selected vehicle speed. The PCM sends a class 2 message to the instrument panel cluster in order to illuminate the cruise control indicator. Pressing the accelerator pedal, while the cruise control system is engaged, will allow the driver to override the cruise control system in order to accelerate the vehicle beyond the current set vehicle speed. When the accelerator pedal is released, the vehicle will decelerate and resume the current set vehicle speed. The driver can also override the current set vehicle speed via the Set/Coast switch and the Resume/Accel switch. When the cruise control system is engaged, pressing and holding the Set/Coast switch will allow the vehicle to decelerate from the current set vehicle speed without deactivating the cruise control system. When the Set/Coast switch is released, the PCM will record the vehicle speed and maintain the vehicle speed as the new set vehicle speed. When the cruise control system is engaged, momentarily pressing the Set/Coast switch will allow the vehicle to decelerate at 1.6 km/h (1 mph) increments for each time that the Set/Coast is momentarily pressed, with a minimum vehicle speed of 37 km/h (23 mph). When the normally open Resume/Accel switch is activated, the switch closes and the PCM detects a high signal voltage on the cruise control resume/accel switch signal circuit. Activating and holding the Resume/Accel switch, when the cruise control system is engaged, will allow the vehicle to accelerate to a greater vehicle speed than the current set vehicle speed. When the Resume/Accel switch is released, the PCM will record the vehicle speed and maintain the vehicle speed as the new set vehicle speed. When the cruise control system is engaged, momentarily activating the Resume/Accel switch will allow the vehicle to accelerate at 1.6 km/h (1 mph) increments for each time that the Resume/Accel switch is momentarily activated, with the maximum acceleration total of 16 km/h (10 mph) over the current set vehicle speed . Momentarily activating the Resume/Accel switch, after the cruise control system has been disengaged by pressing the brake pedal, will recall the previous set vehicle speed that is recorded in the PCM.

"EML" is an acronym for "Elektronische
Motorleistungsregelung". Loosely translated from the original German for the BMW
owner means Electrionic Engine Power
"EML" is BMW's system name for electronic throttle management. The "EML" system, in it's most basic sense consists of an accelerator pedal (with an electronic position sensor), a computer module (usu. integrated with the main engine computer), and an EDK (Elektronische Drosselklappe or Electronic throttle valve). The EDK is also known as a "drive by wire" throttle. "EDK" throttles use a computer controlled stepper motor rather than a purely mechanical linkage (usu. metal cable attached directly to the accelerator pedal) to control the opening and closing of the throttle plate.
"Drive by wire" throttles are very common
on modern vehicles starting in the late nineties up through the present day.
"Drive by wire" technology enables very precise throttle control to improve
drivability and vehicle emissions, as well as many convenience features like
electronic cruise control, traction control & stability control.
BMW first implemented "drive by wire" in very limited quantities on the most expensive & sophistocated BMW models starting in 1988.
The latest generation of advanced vehicle
features to take advandage of "drive by wire" technology are radar guided cruise
control, accident avoidance control, autonomous-driving, and autonomous-parking
