SOURCE: Lincoln LS 2003

my etc light came on and i took to the lincoln dealer it was my fuel system and it had to be replaced for the tune of 800 dollars. after that it ran fine for about a month then i hit a hump then it went into etc mode again. i then took it back to lincoln they did not see a code or that it even went into etc mode because i cut the car off and turned it back on it ran fine but once you cut it off it resets itself it did this about 10 more times and never came back on again knock on woods no problems but it started missing and the check engine light came on it was a misfire in cylinder 4 and it replaced the spark plug myself and it has ran find ever since. I was told anytime the etc light comes on it due to fuel or transmission

SOURCE: does the etc engine fail safe mode engage when

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

SOURCE: 05 lincoln ls was in accident, hit on drivers

I have a 2004 LS V8 & do all my own work

I can understand the battery failed as it was
more than 4 or 5 years old

The converters would have had to be damaged
in the accident if something got under the car
& damaged the exhaust pipes,no other reason

The Gas Pedal is called a Electronic Throttle
Control Module,I'm looking at my wiring diagrams
for a V6 &v8. I don't see that as an issue

The Throttle Body is almost always replaced at a dealer
& seldom an issue either. Reason --When you have a really
bad COP Ignition Coil it spikes your PCM & the signal
comes back on the TPS Sensor on the throttle body &
the pcm looses throttle plate % & starts to cut out
fuel injectors

Bottom line ,not many people like working on Ford Products
& the dealer will really cost you dearly & with negative results.

I have seen many codes related to coils & never more than
one bad one,while it could happen

It sounds as though 80% of your issues have nothing to do
with the accident.

We own one of the most complicated vehicles out there
It has Jaguar Technolgy as well

I don't know if any testing or diagnosing was done on your car
or if what was done invloved a body shop,then off the a dealer
or local repair shop,but I don't get a warm fuzzy fealing on anything
but the battery

As long as your wrench is light you have codes to at least look at

The ETC Failsafe on the right bottom side if dash is a BAD COIL
as I explained above. You will drive up to 22 miles in hot weather

The PCM you can see & feel under & behind the glove box
To remove it you have to remove the box on pass side of engine
compartment that covers the Cabin Filter as the 2 harness connectors
ar there down low

I doubt the PCM Failed

Go to a local shop that likes lincolns & just have them find
the one bad ignition coil.
them it will only go 6 mph in failsafe. Unusable for now

SOURCE: What causes 2004 Lincoln LS with V8 to go into

Over heating causes it to shut down 2 cyl n run on 6 cyl to help cool it down but once that happens the best is to shut it off check the cooling system check for antifreeze make sure its full then take the ground off the battery that's in the trunk beside the spare tire n leave the postive on but take off negative n leave it off for 5 mins then hook it back on it will turn the safe mode off back to normal. That's what I did to my 04 lincoln LS v8 3.9l... hope this helps ya

LIMP MODE HOME


The O2 Sensors need to be changed at 100,000 miles,
before they fail & you get a MIL Lamp on your dash

Just the front (2) closest to the engine, at the converter inlet

The ETC Failsafe, is most likely bad COP ignition coils
Have to check for cylinder misfire count with a professional
scan tool in Mode #06,unless you want to spend a few days
walking a new coil from one cyl to the next

Always provide V6 or V8 in your question & lots of detail

2005 lincoln LS v6 I am getting codes 2107 and 2110. Replaced throttle body and the wrench is still coming up putting the car in safe mode. codes are still the same. Car has only 40, miles


One bad COP Ignition Coil

There was no need to replace a $700 throttle body

One $37.00 coil from Rock Auto online & 20 min of
your time & your done

Not may people can diagnose an L/S for some reason.
That said ,I have no idea how they then could diagnose
any ford product,sad but true.

The coil is spiking the PCM & the signal comes back
on the TPS Sensor & you loose throttle plate % & go into
ETC Failsafe

The TACM Codes (2107 & 2110) and there are others,
are not valid or the problem.

The technology is beyond the pros & dealers as well

I HAVE A 2005 LINCOLN LS V6 THAT GOES TO FAILSAFE MODE I HAVE REPLACED THE COILPACKS AS NEEDED AND THE TACM BUT HASNT SEEMED TO SOLVE MY PROBLEMS NEED HELP


No need to replace an entire throttle body because of a
TACM code or ETC Fail Safe

You need to replace only (1) COP Ignition Coil that is bad
enough to cause your cars problem

It has not been diagnosed properly & I assume at a very expensive
cost to you so far

You could install one coil yourself at $38.00 on the internet,if you
knew how ,15min job.

If the bad coil is on the pass side of engine, then the upper intake
has to come off to get to the coils

Next vehicle,buy a V8

I have a 2005 Lincoln LS. 3.9 v8. The problem started about two months ago. At first, about once a week, the ETC failure safe mode would come on. I could pull over and restart the car and the problem...


You never needed a dealer
You can forget the RF theory,the PCM is inside,behind the glove box
The Throttle Body is $578 at Lincoln, $638 at Ford,if the Throttle Actuator Motor failed (2107 & 2110),but it didn't,just got the code.

You should have PO 301 thru PO 308 codes,all others you disregard

You buy one new coil $59.00 at auto parts store, and it walk down cylinders, until you get the one,spiking the PCM,coming back on the TPS Sensor,then back to PCM,putting it into ETC Failsafe (Electronic Throttle Control) like toyota---drive by wire.

You need a 7mm socket to remove the coil covers and coils,on top of valve covers.

If it was a V6- you get problems,need to remove intake to get to 3 plugs.

Etc fail safe mode codes p2104 2107 2110 2111 2112


P2104 Throttle Actuator Control System - Forced Idle
P2107 Throttle Actuator Control Module Processor
P2110 Throttle Actuator Control System - Forced Limited RPM
P2111 Throttle Actuator Control System - Stuck Open
P2112 Throttle Actuator Control System - Stuck Closed

Seems like Throttle Actuator is the problem.

Good luck on this repair.

2003 Lincoln LS V8, Won't turn over after errors


Forget the four coils. That is a common problem,but I would question 4 failing.
The ABS ,Parking Brake,Speedo Etc,where nothing to worry about,you were loosing power, when it went to fail safe,so they came up.

ETC -is Electronic Throttle Control, your problem? Maybe
You will need to have a scanner put on it's,daignostic connector under the dash,to check for codes. Them only a trained technician can follow a chart or test proceedure to properly repair.
I have a 2004 LS,one of Ford most high tech and complicated vehicles.
Conclusion: only a professional can repair you car.
I would start with a local shop. If money you have money to throw away,go to a dealer.
Most likely have to wave to it on a flat bed carrier. Don't flat tow it.
