    Same thing here. The engine does not shut off but you stop moving and can't excellerate. I was told it may be the antitheft thing. Not sure. Ford is giving me the run around saying its everything but.

    My 06 Expedition is doing the same thing...going into failsafe mode. I have also had a low tire pressure light on for six months that they cannot fix! As far as the fail safe mode, they have quoted me over $800 to replace the sensor in the throttlebody.

    2005 Expedition. My car, without warning, displays the "engine failsafe mode" randomly while driving. It's pretty terrifying. The car just dies without warning. I have to turn it off, then restart and it's ok. Anyone know what this is?

Does the engine completely shut off? It sounds like the electronic throttlebody is causing the problem.

My ford explorer 2005 has a engine failsafe mode

Check engine light on , failsafe mode . The first thing to do would be to hook up a scan tool an check for DTC'S - diagnostic trouble code's . Was the vehicle overheating ? Failsafe mode will shut the vehicle off to save the engine if it is over heating . Do you know if the vehicle has electronic throttle control ? Was their a yellow wrench symbol lit on the instrument cluster as well ?

I have a 2006 Ford Expedition (Eddie Bauer edition). I love the car, but three times now it has just shut off at random while driving it. I receive a Engine Failsafe Mode message and the Check engine...

It's random failure of the ECM. I experienced the type of failure you describe in my '95 Windstar. Sudden total failure and check engine light on. Coasted to a stop (no traffic), let it sit for a few minutes with ignition turned off, then restarted and it ran fine.

2006 f-150 goes into a failsafe mode.In the last month about once a week this did happen. As your driving the engine shuts off and the alert on the odometer says failsafe mode.Have you heard of this...

The dealer is correct but any auto prts store caqn bring the codes up for free as they want to sell you the parts to fix it. Failsafe is involve with exhaust emmissions and the car needs fixed noe before the parts are failed

Hi my 2006 F150 king ranch has shut off twice where it locks up for the engine failsafe then says low oil pressure. after turning off then on, it goes away. Any thoughts? The truck is recently purchased...

Your pickup should have thrown a stored code if it has shut down. Get the code extrracted, and see if it indicates a sensor along with something else. I would advise you to install an after market gauge which operates independantly fron the existing oil pressure circuit to verify that it is a low oil pressure condition the next time it happens.Could be a faulty sensor, but it needs to be verified first.

Enigine fail safe mode

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.
