2004 Acura RSX engine

Your vehicle has certain ‘‘readiness
codes’’ that are part of the on-board
diagnostics f or the emissions
systems. In some states, part of the
emissions testing is to make sure
these codes are set. If they are not
set, the test cannot be completed.
If your vehicle’s battery has been
disconnected or gone dead, these
codes are erased. It takes several
days of driving under various
conditions to set the codes again.To check if they are set, turn the
ignition switch to ON (II), without
starting the engine. The Malf unction
Indicator Lamp will come on f or 20
seconds.If itthengoesoff,the
readiness codes are set. If it blinks
f ive times, the readiness codes are
not set. If possible, do not take your
vehicle f or a state emissions test
until the readiness codes are set. See
State Emissions Testing on pages

If your vehicle needs to be towed,
call a prof essional towing service or,
if youbelongtoone,anorganization
that provides roadside assistance.
Never tow your vehicle behind
another vehicle with just a rope or
chain. It is very dangerous.
There are three popular types of
prof essional towing equipment.
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. The tow
truck uses metal cables with hooks
on the ends. These hooks go around
parts of the f rame or suspension and
the cables lif t that end of the vehicle
of f the ground. Your vehicle’s sus-
pension and body can be seriously
damaged.
If your Acura cannot be transported
by f lat-bed, it should be towed by
wheel-lif t equipment with the f ront
wheels of f the ground. 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. ShifttoD,thentoN.
Turn of f the engine. Start the engine. Release the parking brake.
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).

NOTICE: Improper towing preparation
will damage the transmission. Follow
the above procedure exactly. If you
cannot shif t the transmission or start
the engine (automatic transmission),
your vehicle must be transported with
the f ront wheels of f the ground.

Your vehicle has several identif ying
numbers in various places.
The Vehicle Identif ication Number
(VIN) is the 17-digit number your
Acura dealer uses to register your
vehicle f or warranty purposes. It is
also necessary f or licensing and
insuring your vehicle. The easiest
placetofindtheVINisonaplate

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.
In Canada, Acura vehicles comply
with the Canadian emission
requirements, as specif ied in an
agreement with Environment
Canada, 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 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.

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)
or the Powertrain Control Module
(PCM) uses various sensors to
determine how much air is going
into the engine. It then controls how
much f uel to inject under all operat-
ing conditions.
This system constantly adjusts the
ignition timing, reducing the amount
of HC, CO, and NOx produced.
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
Genuine Acura 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 from
the rest of your vehicle. Read your
warranty manual for more inf orma-
tion.
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 ), nitrogen
(N ), and water vapor.
