SOURCE: 2005 Explorer changed EGR valve

Most likely the ETC Fail Safe (Electronic Throttle Control)
Various Codes for the Throttle Body will be present

Before you replace the Throttle Body because of a failed
TACM (Throttle Actuator Control Motor) Spray the throttle
inlet and plate with CRC Throttle Body Cleaner

The Failsafe can also occur from a really bad COP Ignition
Coil spiking the PCM (computer) and coming back on both
sides of the TPS Sensor. You then loose throttle plate
position and thus shut down or go only 6 mph

SOURCE: engine safe mode with wrench

That should be the drive by wire...remove the duct work to get to the throttle plate carefully open it up and clean inside the throat where the throttle plate is ..use a little brake cleaner on a rag and wipe it out..dont use and kind of wire brush ..sometimes they stick a little and the computer throws it into safe mode

I have a 2004 ford explorer xlt. the indicator says engine fail safe mode. what could be the problem?


Failure Mode Effects Management (FMEM) is an alternate system strategy in the PCM designed to maintain engine operation if one or more sensor inputs fail.
When a sensor input is perceived to be out-of-limits by the PCM, an alternative strategy is initiated. The PCM substitutes a fixed value and continues to monitor the incorrect sensor input. If the suspect sensor operates within limits, the PCM returns to the normal engine operational strategy.
All FMEM sensors display a sequence error message on the scan tool. The message may or may not be followed by Key On Engine Off or Continuous Memory DTCs when attempting Key On Engine Running Self-Test Mode.
With the fail safe mode was the "Service" wrench light lit or check engine light ?

Engine Failsafe Mode is activated


It may be if you ignore the light. Check the oil level and coolant levels first if ok have the fault codes read to determine the sensor that put the light on. Repair it and go from there.. Normally the ECM goes into safe mode to protect the engine and gear box from serious damage but it depends on the driver to react promptly to stop further damage occurring.

2005 ford explorer wont start and says engine fail safe mode with a wrench picture


Is the battery dead?

At least try & get any codes present
before disconnecting it, as you have a wrench light on

That you should know about-system malfunctions & check
lamps have been around for 32 years

Failsafe is either a really bad ignition coil & class A Misfire
that could ruin the exhaust converter or an overheating problem

If you replaced the battery already, read your owners manual
to see how to get the security system clear, if that is even
applicable to your truck. My Lincoln you can do whatever you
want & have non of those issues with batteries & PATS security

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

I have a 2007 ford fusion and its idle by its self my wrench light came on and then went off. its sound like its missing. i know i need and oil change it acts like it dnt wanna take da gas. my check engine...


Normally when the wrench light comes on it relates to the electronic throttle body. When the computer detects a fault with the throttle body it will go into a fail safe mode and limit throttle inputs.
You should get your oil changes on time but I dont think this is your problem. You really need to get the vehicle codes read by the dealer or some auto parts stores read the computer codes for free.

Mrsjd_0998@yahoo.comCheck on light comes on then the a small wrench icon appears. The message along with check engine now says engine in safe mode. The car loses all pick up. whats the problem


safe mode means the computer is protecting the engine by shutting down some operations - like half the cylinders.

go to autozone & have codes read (DTC) free.

Wrench light


It may be that your TPS (Throttle Position Sensor) is bad or dirty. Try cleaning it, and if that doesn't work, then replace it. It goes for about $45, but if you take it to the stealership they'll run you over $200.
I had the same problem and got it fixed. Takes a couple of minutes.
