ETC Failsafe Mode- 2003 Lincoln LS -v8 85,000 miles
I have been having this trouble for a good 6 months. I have learned to live with it...I can never tell when it is going to happen. My car thinks it is over heating...I will be driving along sometime doing a steady speed and sometimes from a dead stop- push on the gas and the ETC Failsafe Mode comes on. If I turn off the car and turn it back on- no problem. When I am driving I will feel the car start to run a bit rough and struggle to get into forth or fifth gear...or maybe better said- get in but not feel like it is using all the horses or valves...I don't know- The car is NOT over heating...the temp gauge is right in the middle- I have antifreeze in the resivoir...no problems....Also, I make one particularly hard 90 degree turn everyday near my house. I slow down or begin to coast through the turn...and as I come out of the turn I give it gas and it happens there...it is almost like when the steering wheel is turned hard in a right hand turn and gas is given- it goes into this mode...I see it happening in the low gear (1st and 2nd) almost like the computer timing gets funked...Is there a way to reset the computer? Could it be a computer problem? I spoke to Lincoln mechanic and he said that a censor could be broken- but he wouldn't be able to tell until he hooks up the car and reads what the computer says...Could I reset the computer by unhooking the battery and rehooking it up? Is there a way to just turn this failsafe mode off completely- because if the car is not over heating and that is what it thinks it is doing then just bypass the ETC Safemode- or is theETC Safemode language for more than just overheating the engine...
I love this car- It has so much power and the handling is great. I have not had to do anything but routine service- tires, oil, brakes- and I have learned to actually drive the car and not have this happen- but come on- I shouldn't have to drive my car a certain way...i should be able to drive it like a normal car...not only that- but it is dangerous...how can Lincoln make something on a car where you lose all power...I have tried pulling out onto the Somerville NJ circle and this happened and almost got tboned...this is not a safety mechanism- it is going to get someone killed...
Can you please help me? Why is this doing this? What could it be? How can I fix it? What exactly am I looking at here?

Re: ETC Failsafe Mode- 2003 Lincoln LS -v8 85,000 miles
The ETC going into safe mode because PCM sees something wrong that it believes will interfere with throttle control. It goes into failsafe so as to not loose control and have an unattended acceleration and cause you to crash.
Now what almost always causes this ,95 % of the time on this vehicle is a bad coil pack. It will usually show up a wide open throttle almost everytime when your rpm's get close to 5-6k rpm's.
It will feel like you reach up and turned the igntion switch off and back on. The only for sure way to tell which coil or coils are causing this is to have the dealer do a stress test on them.
It could also be the valve cover orings maybe leaking and getting oil on the coil packs,you can verify this be removing the coil packs and seeing if spark plug wells are full of oil.
The only other thing I have seen on this model that may cause this is a coolant control valve shorting out.
Re: ETC Failsafe Mode- 2003 Lincoln LS -v8 85,000 miles
My Lincoln LS V8 did this and I replaced all 8 coil packs and relaced all 8 spark plugs...expensive but runs like new again...dearlership in Calhoun tried rippiing me off with expensive "let's throw parts at it" mentality and I refused...figured it out with code P0352 which the dearler said they weren't sure which coil it was...a joke! Another dearlership pinpointed the #2 coil but due to the milage I went ahead and did it right. Under 100,000 miles they are covered by warranty.

Have you replaced ignition coils on this car previously? If so, did you use OEM Motorcraft coils, not aftermarket? The aftermarket coils do not play well with the PCM on this car, causing it to do goofy things including having it go into the ETC Failsafe mode. This is likely your issue since coil issues are common on this car. If it is not, let me know
HAVE TO USE OEM-- NGK -- Plugs (Rock Auto.Com
or NGK web site)
I said OEM Tip Config,NOT ford parts,they
were NGK off the assy line. The ford ones are the
WRONG tip,those folks don't care!
Replace ALL the COP Ignition Coils
The coils are your ONLY Problem
I know because I have a 2004 L/S & ten years diagnostic
experience with them, with professional tools
You only have 2 Fail Safes
one for overheating & one that says ETC
Don't even try to figure out the obd codes or the etc thing
Take too long to explain
The dealers can't fix that car,the coils when they get really
bad spike the drivers in the pcm & you loose tps signal & go into
etc failsafe & can only go 6 mph
There is no factory manual that tells you that & your etc on a
wiring diagram is the app or gas pedal,but on the obd codes it
is the throttle body P2100 codes that point to the motor or
tacm,& that is not the problem
So the answer is-- no one likes or understands that car, nor can they
fix one,so replace all the coils yourself,they only last 6 to 7 years
Only need on 7mm socket & get the coils from RockAuto,Com
I use Wells Coils
The front Oxygen Sensors have to be replaced at 100,000 miles
Better be changing that Tran Fluid on ALL your vehicle every 2 or 3
year or they WILL FAIL I guarantee it & power steering fluid also
You have a really bad COP Coil spiking the PCM,
the signal comes back on the TPS Sensor
and you loose TPS input and then PCM doesn't
know where the throttle is positioned,so it shuts
down the injectors,puts you into ETC Failsafe
and you can only go 6 mph,and gives you TACM
Codes (throttle actuator control motor-the motor
on the throttle body ,you got twice, you didn't need)
I have a 2004 LS V8
I solved that issue for $59.00 plus tax for
(1) COP Coil from the local auto parts store
Now I did have to walk the coil on a 90 degree
day and drive exactly 22 to 26 miles each time
to find the offender.
A Dealer can not fix it
They don't even road test,look at your
in and out mileage.
Recently put an old oscilloscope from a scanner that is
obsolete, on my O2 Sensors
They came up okey but 108,000 miles
Installed new OEM NGK sensors,it is like day and
night,like a new car (wifes car,I like trucks and old stuff)
My coil problem was the second in 2010
I have had lots of challanges with the LS
Never go to a dealer with any vehicle
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)
I have a 2003 V6 lincolin LS with codes 2107/2110, I've changed everything but the plugs and the cam postion sensors. make sure you use Iridum spark plugs, with the gap at .051. Once I did this and replaced the cam sensors the car runs great no wench light. At 150 miles and 3 days,so far with no problems.It took me about 6 months to get it right. And I don't want anyone to go through what I did. I hope This helps.
Bad ignition coil,spiking the PCM,spike comes back on TPS Sensor,then to PCM again,putting the car into ETC Failsafe,and you can only go 6 MPH.
If the coils are not the issue,then the 2110 & 2107 come into play, and you spend $700,00 just for a new throttle body. The motor in it is not replaceable as of 2010,may be some day
In that case you better put it on yourself. Only (4) 10mm bolts,but you have to drain a little coolant,as it goes thru the throttle housing
