s Control s
Onboar d Refuelin g Vapo r
Recover y
The Onboard Refueling Vapor Recovery (ORVR) system captures
the fuel vapors during refueling. The
vapors are adsorbed in a canister filled with activated carbon. While driving, the fuel vapors are drawn
into the engine and burned off.
Exhaus t Emission s Control s
The exhaust emissions controls include three systems: PGM-FI,
Ignition Timing Control and Three
Way Catalytic Converter. These three systems work together tocontrol 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 andevaporative emissions control

systems.
PGM-FI System

The PGM-FI System uses sequential multiport fuel 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 fuel to inject under all operat- ing conditions.
Ignition Timing Control System
This system constantly adjusts the ignition timing, reducing the amountof HC, CO and NOx produced.
Three Way Catalytic Converter
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 (C02), dinitrogen (N2), and water vapor. Replacemen
t Part s
The emissions control systems are designed and certified 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 newGenuine Acura replacement parts or
their equivalent for repairs. Using
lower quality parts may increase the emissions from your car.
The emissions control systems are covered by warranties separate from
the rest of your car. Read your
warranty manual for more informa- tion.

Thre
e Wa y Catalyti c Converte r
The three way catalytic converter contains precious metals that serveas catalysts, promoting chemical
reactions to convert the exhaust
gasses without affecting the metals.
The catalytic converter is referred to as a three-way catalyst, since it acts
on HC, CO, and NOx. A replacement
unit must be an original Acura 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 fire any com-
bustible materials that come near it. Park your car away from high grass,dry leaves, or other flammables. A defective three way catalytic
converter contributes to air pollution,
and can impair your engine's per-
formance. Follow these guidelines to
protect your car'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 ineffective. Keep the engine tuned-up.
Have your car diagnosed and
repaired if it is misfiring, back-
firing, stalling, or otherwise not running properly.

Stat
e Emission s Testin g

Testin g o f Readines s Code s
If you take your vehicle for a state emissions test shortly after the
battery has been disconnected or
gone dead, it may not pass the test.
This is because of certain "readiness codes" that must be set in the on-
board diagnostics for the emissions systems. These codes are erased
when the battery is disconnected, and set again only after several daysof driving under a variety of
conditions.
If the testing facility determines that
the readiness codes are not set, you
will be requested to return at a later date to complete the test. If you must
get the vehicle re-tested within the
next two or three days, you can condition the vehicle for re-testing
by doing the following. Make sure the gas tank is nearly,
but not completely, full (around 3/4). Make sure the vehicle has been
parked with the engine off for 8
hours or more. Make sure the ambient

temperature is between 20° and 95°
F.
Without touching the accelerator
pedal, start the engine and let it
idle for 20 seconds. Keep the vehicle in Park
(automatic transmission) or
Neutral (manual transmission).
Increase the engine speed to 2,000
rpm and hold it there until the
temperature gauge rises to at least 1/4 of the scale (approximately 3
minutes).
