Warning: fail safe engine mode

While driving, the panel displayed "fail safe engine mode". I was still able to drive, but I'd like an idea of what this error message is describing.

I do not know about a Jag. But the "fail safe engine mode " on my GMC means the Engine Controll Computer has quit working.

Engine Failsafe Mode came on after cleaning battery cables. Vehicle will start, but won't run. No throttle


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

"fail safe engine mode". this warning comes on constantly when driving usually in poor weather conditions


This warning means that a fault has occurred that would have disabled the car in older models, the computer control has worked around the fault to avoid stranding you with a non operational car. You need to see a dealer or a well equipped shop and have the computer scanned for the fault code or codes that are stored when this happens. The engineers who design cars and trucks call this "Failure Mode Strategy"

Smart car keeps cutting out whilst driving


If all power is lost in the car, it could indicate a bad battery connection, bad wiring, or loose main wire harness, etc.

If a warning light comes on - it may be going in to Safe Mode.

Safe mode is the set of parameters that the car will use if it believes there
is a fault with the engine that could cause irrepairable or long term damage.

Generally it is an excess in expected boost pressure entering the engine.
This excess boost from the turbo tends to happen for 4 reasons.

The boost pressure sensor (MAP sensor) is faulty.
The wastegate is seized shut or slightly open.
The wastegate actuator is faulty.
The air line to the wastegate actuator is damaged or off.

Obviously, if the sensor is faulty, it will tell the ECU lies about the boost pressure.
If the wastegate assembly fails in any way it will fail to open to bypass the turbo.
The turbo will continue to spin up, increasing the boost pressure, causing the fault.

Initially I would suggest disconnecting the battery for 5 minutes (make sure you know your
radio code before doing this), this will turn safe mode off and your car should run normally
again. Drive home with a bit of care, you may find the car might never do it again. If it does
go into safe mode again, you know you have a real problem and not just a glitch.

Best to contact your dealer and have it checked out.

Check engine come on code po446 hoow u that?


The "check engine" warning light advises that the vehicle is in "fail safe" mode. That means only some of the car's capabilities are operational, just enough to get you to the nearest service point. You probably should not drive it any further than that. Have your service man download and analize the fault codes from the ECM which will indicate what the problem code is.

Does the etc engine fail safe mode engage when driving 20mpg or less in snow? I love 2003 lincoln LS. This question is not addressed in the owner's guide.


the engine fail safe [limp mode] engages for or when the engine/trans senses damage or something that can cause extreme damage[ no oil pressure] the limp mode is so u can safely get off road or to a service location

BMW x5 warning light fiasco


Hello This is Mike,,

Sometimes.... Sometimes this will take care of some of those faults and codes, and it only takes a few minutes to do. I know your problem is not exact as this reset method says, but however you would be amazed on this fixes a lot of things, it like a cheap way to reset computer and fixes a lot of things back to default mode. Try it and let me know. Mike

IT'S VERY EASY TO RESET THE TRANSMISSION'S COMPUTER. HOLD GAS PEDAL DOWN. TURN THE KEY TO THE NUMBER TWO. CONTINUE TO HOLD THE GAS PEDAL DOWN FOR THIRTY SECONDS.RELEASE THE GAS PEDAL AND PRESS THE BRAKE PEDAL FOR TEN SECONDS. NOW YOU CAN TURN THE VEHICLE ON. THAT SHOULD TAKE IT OUT OF SAFE MODE

Enigine fail safe mode


I encountered the same problem, my engine fail safe mode light came on and shut the car down. I took my car to my mechanic and he found the solution to the problem. The car needed a throttle body cleaning and the fuel filter needed to be replaced. After having my truck serviced my mileage increased from 14.6 mpg to 15.4 mpg

Sounds like you maybe having a sensor failure (engine). A computer diagnostic can be performed at the vehicle dealership to determine what caused the fail safe mode to activate.

Why did i buy a ford


most vehicles that are new have a fail safe. most of the time when this ingages it has to do with low fluid levels especially low coolant. no codes thrown on the computer presents a unusual problem because when the fail safe ingages it should auto matically throw a code. tell me when you first start it does it drive normal for a while?
