Today the engine failsafe mode message was on my dash display. What does this mean?

Connect it to a professional grade scan tool computer.

Sometimes the engine failsafe mode is triggered due to a sensor failure or an electrical glitch. It's also common for a security system fault to engage this warning light, which means it's not always a mechanical issue that's causing the failsafe.

what your codes mean

Check Engine Light On, P0300 Random Misfire Code. A random misfire means your engine is misfiring, but that the problem is not isolated to one or two cylinders. It is jumping around in a random way from one cylinder to another. A random misfire code usually means the air/fuel mixture is running lean.

What the P0700 code means. P0700 is set when the PCM detects a malfunction in the transmission control system. This malfunction causes the vehicle to set a Check Engine Light and trigger a failsafe mode. Once the failsafe mode is set it will remain until the fault is repaired or normal operation is detected.

PO133 Oxygen Sensor Circuit Slow Response (Bank1, Sensor1)

means overheated, underoiled, ecu issue and plenty more. get a code scanner to identify

Fail safe is TPS sensor. When you go in fail safe the vehicle give a set amount of RPM and no throttle response the rule of thumb in fail safe is APP1 and APP2 does not agree the goal is to protect the catalytic convertor. So if the transmission was at fault you dont over rev to end up burning the Cat. Or over rev to break the engine It all boils down to a throttle body assembly as the solution

Hi there, Failsafe engine mode means that there's something wrong with your car. This feature limits you to 30% throttle to allow you to get safely off the highway or to a shop. It is a safety feature so you're not stranded somewhere.
This is most commonly seen when the brake switch goes - it is possible to fix it with a lot of WD40 to get the contacts going again. The brake switch is under the dash connected to the brake arm.
If you take it into a shop, they may want to replace it. It will be at least $50 for the part.

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

Go to your local garage (anyone) and have them read the OBDII code this will tell you what has caused the problem, cost for this should be minimal £7-10 ask them for all the reported codes you can check them out at http://www.bluejag.co.uk if you wish to find out what they mean.

Hi; If I get the 'Trans Failsafe Prog" message twice within about 2 hours, The SES light will go on automatically. Since I do not seem to have any real transmission problems, this SES message clears itself in about 24 hours. The "Trans Failsafe Prog" messageseems to be used to indicate other transmission problems as well, like loss of transmission fluid, so be careful. I have a 2002 X5. Cheers. Omer

The failsafe mode can appear following numerous faults being detected - some faults can be momentary and register but not cause a problem. These are normally reset by just turning ignition off/on. get the fault code memory read at a garage and this may give you a clue as to a possible problem developing. Failsafe mode will give you reduced engine performance but will allow you to drive for normally some distance. If a serious problem developes your car message centre will tell you to shut off the engine or it will shut it down.
good luck.
