2004 HONDA CIVIC HATCHBACK engine

Turn the ignition switch to LOCK
(0). Make sure the headlights and
all other accessories are of f .
Remove the cover f rom the f use
box.
Check each of the large f uses in
the under-hood f use box by
looking through the top at the wire
inside. Remove the screws with a
phillips-head screwdriver.
The vehicle’s f uses are located in
two fuse boxes. The interior fuse
box is located underneath the
steering column. To open it, turn the
knobsasshown.
If something electrical in your
vehicle stops working, check f or a
blown f use f irst. Determine f rom the
chart on pages and ,or the
diagram on the f use box lid, which
f uses control that device. Check
those fuses first, but check all the
f uses bef ore deciding that a blown
f use is the cause. Replace any blown
f uses, and check if the device works.
The under-hood f use box is located
in the back of the engine
compartment on the lef t side. To
open it, push the tabs as shown. 1. 2. 3.

If your vehicle needs to be towed,
call a prof essional towing service or
organization. Never tow your vehicle
with just a rope or chain. It is very
dangerous.
The operator
loads your vehicle on the back of a
truck.
The tow
truck uses two pivoting arms that go
under the tires (f ront or rear) and lif t
them of f the ground. The other two
tires remain on the ground. With the f ront wheels on the ground,
it is best to tow the vehicle no farther
than 50 miles (80 km), and keep the
speedbelow35mph(55km/h).
If your vehicle is equipped with a
f ront spoiler, remove it bef ore
towing so it is not damaged.

If , due to damage, your vehicle must
be towed with the f ront wheels on
the ground, do the f ollowing:
Release the parking brake.
Shif t the transmission to Neutral.Flat -bed Equipment

NOTICE: NOTICE:
Improper towing preparation
will damage the transmission. Follow
the above procedure exactly. If you
cannot shif t the transmission or start
the engine, your vehicle must be
transported with the f ront wheels of f
the ground.
Trying to lif t or tow your
vehicle by the bumpers will cause
serious damage. The bumpers are not
designed to support the vehicle’s weight.

Your vehicle has several identif ying
numbers located in various places.
The Vehicle Identif ication Number
(VIN) is the 17-digit number your
Honda dealer uses to register your
vehicle f or warranty purposes. It is
also necessary f or licensing and
insuring your vehicle. The easiest
placetofindtheVINisonaplate
fastened to the top of the dashboard.
Youcanseeitbylookingthrough
the windshield on the driver’s side. It
is also on the Certification label at-
tached to the driver’s doorjamb, and
is stamped on the engine com-
partment bulkhead. The VIN is also
provided in bar code on the
Certif ication label.

The burning of gasoline in your
vehicle’s engine produces several by-
products. Some of these are carbon
monoxide (CO), oxides of nitrogen
(NOx) and hydrocarbons (HC).
Gasoline evaporating f rom the tank
also produces hydrocarbons. Con-
trolling the production of NOx, CO,
and HC is important to the environ-
ment. Under certain conditions of
sunlight and climate, NOx and HC
react to f orm photochemical ‘‘smog.’’
Carbon monoxide does not contri-
bute to smog creation, but it is a
poisonous gas. The United States Clean Air Act
sets standards f or automobile
emissions. It also requires that
automobile manufacturers explain to
owners how their emissions controls
workandwhattodotomaintain
them. This section summarizes how
the emissions controls work.
Scheduled maintenance is on page
.
In Canada, Honda vehicles comply
with the Canadian Motor Vehicle
Saf ety Standards (CMVSS) f or
Emissions valid at the time they are
manuf actured.
Your vehicle has a Positive
Crankcase Ventilation System. This
keeps gasses that build up in the
engine’s crankcase f rom going into
the atmosphere. The Positive Crank-
case Ventilation valve routes them from the crankcase back to the
intake manif old. They are then
drawn into the engine and burned.
As gasoline evaporates in the f uel
tank, an evaporative emissions
control canister f illed with charcoal
adsorbs the vapor. It is stored in this
canister while the engine is of f . Af ter
the engine is started and warmed up,
the vapor is drawn into the engine
and burned during driving.
The Onboard Ref ueling Vapor
Recovery (ORVR) system captures
the f uel vapors during ref ueling. The
vapors are adsorbed in a canister
f illed with activated carbon. While
driving, the f uel vapors are drawn
into the engine and burned of f .

The exhaust emissions controls
include three systems: PGM-FI,
Ignition Timing Control, and Three
Way Catalytic Converter. These
three systems work together to
control the engine’s combustion and
minimize the amount of HC, CO, and
NOx that comes out the tailpipe. The
exhaust emissions control systems
are separate from the crankcase and
evaporative emissions control
systems.The PGM-FI System uses sequential
multiport f uel injection.
It has three subsystems: Air Intake,
Engine Control, and Fuel Control.
The Engine Control Module (ECM)
uses various sensors to determine
how much air is going into the
engine. It then controls how much
f uel to inject under all operating con-
ditions.
This system constantly adjusts the
ignition timing, reducing the amount
of HC, CO, and NOx produced.
The three way catalytic converter is
in the exhaust system. Through
chemical reactions, it converts HC,
CO, and NOx in the engine’s exhaust
to carbon dioxide (CO ), dinitrogen
(N ), and water vapor.The emissions control systems are
designed and certif ied to work to-
gether in reducing emissions to
levels that comply with the Clean Air
Act. To make sure the emissions
remain low, you should use only new
Honda replacement parts or their
equivalent f or repairs. Using lower
quality parts may increase the
emissions f rom your vehicle.
The emissions control systems are
covered by warranties separate f rom
the rest of your vehicle. Read your
warranty manual f or more inf orma-
tion.

The three way catalytic converter
contains precious metals that serve
as catalysts, promoting chemical
reactions to convert the exhaust
gasses without af f ecting the metals.
The catalytic converter is ref erred to
as a three-way catalyst, since it acts
on HC, CO, and NOx. A replacement
unit must be an original Honda part
or its equivalent.
The three way catalytic converter
must operate at a high temperature
for the chemical reactions to take
place. It can set on f ire any com-
bustible materials that come near it.
Parkyourvehicleawayfromhigh
grass, dry leaves, or other f lamma-
bles.A defective three way catalytic
converter contributes to air pollution,
and can impair your engine’s per-
f ormance. Follow these guidelines to
protect your vehicle’s three way
catalytic converter.
Always use unleaded gasoline.
Even a small amount of leaded
gasoline can contaminate the
catalyst metals, making the three
way catalytic converter inef f ective. Keep the engine tuned-up.
Have your vehicle diagnosed and
repaired if it is misf iring, back-
f iring, stalling, or otherwise not
running properly.
