Engine failsafe mode light stays on . Explorer was running fine before being parked for three weeks. Found the accessory switch was left on and battery completely dead.

I don't know how old the battery is but just to make sure its ok have it load tested. If battery is good after load testing then have vehicle scanned for codes and see what ECU says about the fail safe lite( what made it come on). Lastly have codes removes and ECU reset.
Usually if you didn't have an electrical problem (battery dying) I would say the output shaft is worn time for a rebuild.

Just got my 2005 Explorer fixed. I had alarms start with Gas Cap, then Avdtrack, then ABS and finally the dreaded fail safe mode. After a new PCM, Thottle body and pedal. Two weeks and $1,900 later, the tech found a Junction box mounted to the frame just below the passenger side door was full of water. He loaded it with dielectic grease and I am cruising.

I just had a motor put in and my a t temp light is flashing from the moment gee started the car ...doesnt appear to be shifting and kicks hard in first ...rmp run over 3 all the time ..changed filter and...

First thing I would check is transmission fluid level. The fluid should be checked with engine warm, engine running, in park and good idea to have emergency brake on. You may know this but many people check transmission with engine off and think it is overfilled. I met one a couple months. It happens.

Failsafe engine mode

You might try to have your battery tested. The Anti-theft system reacts to low battery voltage and automatically reduces the Voltage to the starter so it will not turn over or turn over fast enough to start; thereby defeating thieves.

Failsafe usually is an extreme heat sensor mode which deactivates some of the cylinders so the engine exhausts excess heat through the exhaust valve. This is why top speed is limited and power is reduced. The deactivated cylinders act like air compressors, they have no fuel charge, and thereby draw air into the cylinder and expel heated air.

No way to guess at this symptom,too many possible causes.You will need to have the diagnostic codes retrieved from the computer by a repair shop or a parts store.When I have that information I would be happy to make a recomendation as to a repair.Thanks!

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

Solution for the message "engine fail safe mode" in explorer 2005

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

Vehical stuck in limp mode

This only applies if you have an allison transmission, which based on the problem you are reporting I would guess that you do.

It sounds like your vehicle is stuck in limp mode. This is probably due to a bad NSBU switch(Neutral, saftey, back up) (if you have an allison transmission. Prior to 2002 the NSBU switches had a very poor seal which resulted in water intrusion into the NSBU switch causing corrosion. If the switch is corroded it is likley confusing your transmission. Unfortunatly you cannot repair the bad switch, it needs to be replaced. If you order one through Chevy it will cost around 200 dollars. I found one at merchant Automotive for 91 dollars. ( ).

The switch is relativly easy to replace. the electrical connections are the hardest part as they are glued into the switch. A little heat from a butane torch should soften it up and make the connectors slide off more easily. Other wise you may have to break the NSBU switch appart to remove the connectors.

I replaced the switch for the first time and it took me 15 minutes.

Failsafe engine mode light comes on, codes

Just a quick mention - for about a month my XK8 low coolant light came on intermittently. This week with no notice while driving normally I got Stability Control Fail and FailSafe Engine Mode and wtih great difficulty got the car back to where I started from (less than a mile). Two days later (when got time) and after a bit of research, I tried it again - same problem and a very unhappy engine. I then disconnected the battery for 15 minutes (probably more) to clear the engine codes as well as check all the wiring and vacuum stuff I could under the hood (at a Jaguar master mechanic's recommendation). No problems found but the car would start and immediately stall with the air intake hose disconnected from the intake butterfly. After I reconnected the air intake hose, she started and purred like normal. The problem is the BATTERY... It is low - I've known it for a LONG time BUT it always started right up and never skipped a beat. I intend to replace it tonight but fully expect that's the issue. I've had the car 6 years (it's a 98) and had NO problems except a dead taillight asembly.

Hope this is of value...
