Go to an auto parts store, like Autozone and have them do a free readout of your onboard computer. They can tell you what codes are turning on the check engine light and what they generally mean. You can decide from that information what to do next.
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
Is your check engine light on ? Should be on dash a yellow light that says (check engine soon) If it is go to your local Auro Zone and they will run a code scanner and give you a detailed readout on paper as to what the codes say is the problem,,,,,,,,,,,,,Im thinking your oxy sensors are bad, But you go check it out.
You have a very bad COP Ignition Coil,that is spiking the PCM (computer)
The spike comes back on the TPS Sensor,then the PCM doesn't see the
throttle signal your foot sent thru, the pedal actuator (gas pedal) ,so it puts the
car into ETC Failsafe,and you can only go 6 mph.
If you got no ETC Failsafe, on the bottom right side of the dash, tell me what you do have
I need all the codes,if you have a MIL Lamp on ( the one that looks like a wrench)
it says limp-home operations what does that mean and what is the real promblem that is occuring with my mustang. my warning display is stating engine failsafe mode when i was driving also felt no pick up for a couple of miles. please answer
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
fail safe mode is something the vehicle computor will go into when there is a problem with the vehicle it allows u to get off the highway or road safely you need to take vehicle to repair shop or your dealer which ever u prefer
Failsafe engine mode on a 2000 jaguar s type is caused by a stopped up throttle body. Jaguar says not to clean the throttle body since it has a protective coating to help keep deposits from accumulating. You can clean the throttle body as long as you use ONLY throttle body cleaner that states it is safe to use with a protective coating. The butterfly valve in the throttle body will actually stick not allowing air to flow into the manifold causing failsafe engine mode to kick in reducing the amount of power your engine will produce. To solve the issue just clean out your throttle body, it will cost you around $5 dollars and take 1 hour of your time.
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.
