You will need to scan the computer and see what codes are stored, this may be caused by a bad gas pedal sensor or a bad throtlebody asm, this is a little dificult for a regular person to diagnose due the the reasons that a scan tool is needed and also knowing about the system. without a scan tool you will just be guessing. i would first recommend checking with the dealer for any recalls on this problem, if this is not warantied then first go to an auto part store and check the codes, they will scan it and give you the codes, write me back with the codes and i will try to help you, a common problem with these is the throtlebody goes bad, the sensors inside the throtle go bad but get me the code first. good day.

It should be noted that the ETC - electronic throttle control system includes a warning indicator, wrench warning indicator, on the instrument cluster that illuminates when a concern is present. Concerns are accompanied by diagnostic trouble codes (DTCs) and may also illuminate the malfunction indicator lamp (MIL). (check engine light ) Ford Electronic Throttle Body Failure Diagnosis

Problem with the electronic throttle control .
It should be noted that the ETC system includes a wrench light on the instrument cluster that illuminates when a fault is detected. Faults are also accompanied by DTCS and the "Check Engine Soon" light. Your best bet is to take your vehicle to a reputable ASE certified repair shop .
Overview The Generation II (Gen II) Torque Based Electronic Throttle Control (ETC) is a hardware and software strategy that delivers a transmission output shaft torque (via throttle angle) based on driver demand (pedal position). It utilizes an electronic throttle body, the PCM and a accelerator pedal assembly to control throttle opening and engine torque. The ETC system basically replaces the standard cable operated accelerator pedal, idle air control (IAC) motor, 3-wire throttle position sensor (TPS) and mechanical throttle body .

How do i fix... wrench light ford fusion 2006


You never need to top off fluids

If you do- you have a leak to be repaired

Check the vehicles systems for codes,
then google those codes to see the problem

TYPE: OBD & your code

It is going into ETC Failsafe or something

Do not use it at all,you may have converter ruining
cylinder misfires, from bad ignition coils

You add NO WATER to any vehicle

Distilled water & coolant only

2004 Ford Explorer has trouble starting and once shut down as my wife was driving it!


2004 Ford Explorer: the wrench light came on - which according..limp

Customer Question

My husband wash the engine of our 2004 Ford Explorer. About 2 hours later the wrench light came on - which according to the manual it has something to do with the Electronic throttle control and now I guess it is running in default "limp-home" operation?? Sounds serious. What does this mean since there is no other explanation in the manual.
Hello and welcome to Just Answer!this vehicle uses an electric throttle control system and has no throttle cable or mechanical link between the accelerator pedal and the throttle body on the engine. This is commonly known as "throttle by wire". When the wrench light comes on, it signifies that there is a problem with the electronic throttle control system. The system consists of accelerator pedal position sensors, or sensor on the throttle pedal (there are more than one as back ups incase one fails), throttle position sensors out on the throttle body itself and there are more than one of these too and a throttle motor that actually opens and closes the throttle plate. If the system detects a fault in any of the sensors or the motor itself, it will turn on the wrench light and go into "limp mode". In limp mode, depending on what the computer thinks is wrong, it will either limit the throttle to about 35% or it will command idle and won't let the engine accelerate at all. It does this because when a sensor fails, the system's ability to control the throttle is compromised and as a safety meausre to keep the engine from accelerating when not commanded to do so, the throttle is limited. this problem is likely due to water intrusion into a sensor or an electrical connector. I never recommend using a water hose to clean an engine as water can infiltrate connectors and sensors and cause problems.This is not an easily diagnosed problem and if it doesn't go away when the water dries, will have to be taken to a diagnostic shop to be trouble shot and repaired.

05 lincoln ls was in accident, hit on drivers side, airbag deployed from drivers seat, seat belt light on, engine light on, wrench light comes on and goes into limp home mode. Was told needed to throttle...


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

2005 Explorer changed EGR valve due to code and now fail safe mode is in and wrench light is on. Vehicle starts but throttle does not work.


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

The electronic throttle control light turns on from time to time. when it happens, the gas pedal doesn't work, the car can just slide forward slowly. What the problem could be?


A COP Ignition Coil, spiking the PCM and coming back on the
TPS sensor
Then you loose TPS Data, and the injection is cut on & off
If it gets real bad, it will go into ETC (Electronic Throttle Control)
Failsafe and you can only go 6 mph

What ETC Codes do you have? (MIL Lamp on dash--wrench)

Pray you have none, as the TACM (throttle actuator control motor)
is not something you ever want to write a check for

If you stay away from a dealer and work with me,you save $4000.00
min on your LS. over time My wife has a 2004

Carefully remove the ducting and spray the throttle plate with CRC
Throttle Body Cleaner
Remove & spray the MAF Sensor with CRC MAF Cleaner.

Check your O2 Sensors, for coming loose in the converters
