Failsafe engine mode

Question 1

2answers

Had a missing cylinder. Bad spark plug. Runs great but the engine fail safe light comes on after driving a bit and the check engine light doesn't. When I start the truck the fail safe turns off.

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.

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

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 ?

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

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?

Go to a parts store and have the codes read(most of them will do it for next to nothing. There is also more than likely some maintenance needed. get back to me when you have the codes and we can diagnose this together.

Just because there is a code does not necessarily mean that part is bad, but an area to test to find the actual problem.
