2001 Acura TL ignition

This indicator comes on f or a f ew
seconds when you turn the ignition
switch ON (II). If it comes on at any
other time, it indicates one of the
engine’s emissions control systems
may have a problem. Even though
you may f eel no dif f erence in your
car’s perf ormance, it can reduce
your f uel economy and cause your
car to put out excessive emissions.
Continued operation may cause
serious damage.Youshouldalsohavethedealer
inspect your car if this indicator
comes on repeatedly, even though it
may turn of f as you continue driving. If the indicator remains on past three
driving trips, or the f uel cap was not
loose or missing, have the car
checked by the dealer as soon as
possible. Drive moderately until the
dealer has inspected the problem.
Avoid full-throttle acceleration and
driving at high speed. If you have recently ref ueled your
car, the cause of this indicator
coming on could be a loose or
missing f uel f ill cap. Check the cap
and tighten it until it clicks several
times. Replace the fuel fill cap if it is
missing. Tightening the cap will not
make the indicator turn of f
immediately; it takes at least three
driving trips.

If you keep driving with the
malf unction indicator lamp on, you can
damage your car’s emissions controls
and engine. Those repairs may not be
covered by your car’s warranties.

If it comes on at any other time, it
indicates a problem with the car’s
brake system. In most cases, the
problem is a low f luid level in the
brake f luid reservoir. Press lightly on
the brake pedal to see if it f eels
normal. If it does, check the brake
f luid level the next time you stop at a
service station (see page ). If the
fluid level is low, take the car to your
dealer and have the brake system
inspected f or leaks or worn brake
pads.
However, if the brake pedal does not
f eel normal, you should take
immediate action. Because of the
brake system’s dual-circuit design, a
problem in one part of the system
will still give you braking at two
wheels. You will f eel the brake pedal
go down much f arther bef ore the car
begins to slow down, and you will
have to press harder on the pedal.
The distance needed to stop will be
much longer.Slow down by shif ting to a lower
gear, and pull to the side of the road
when it is saf e. Because of the
longer distance needed to stop, it is
hazardous to drive the car. You
should have it towed, and repaired as
soon as possible. (See
on page .)
If you must drive the car a short
distance in this condition, drive
slowly and cautiously.

It comes on and stays lit if you do not

Turn the ignition switch to LOCK
(0). Make sure the headlights and
all other accessories are off.
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. Removing these f uses
requires a Phillips-head screw-
driver.
Check the smaller f uses in the
under-hood f use box and all the
fuses in the interior fuse boxes by
pulling out each f use with the f use
puller provided in the under-hood
fuse box.
If something electrical in your car
stops working, the f irst thing you
should check f or is a blown f use.
Determine f rom the chart on pages
and , or the diagram on the
fuse box lid, which fuse or fuses
control that component. Check those
f uses f irst, but check all the f uses
bef ore deciding that a blown f use is
not the cause. Replace any blown
f uses and check the component’s
operation. 3.

If you decide to tow your car with all
f our wheels on the ground, make
sure you use a properly-designed and
attached tow bar. Prepare the car for
towing as described above, and leave
the ignition switch in Accessory (I)
so the steering wheel does not lock.
Make sure the radio and any items
plugged into the accessory power
socket are turned of f so they do not

Trying to lif t or tow your car by the
bumpers will cause serious damage.
The bumpers are not designed to
support the car’s weight.
The steering system can be damaged if
the steering wheel is locked. Leave the
ignition switch in Accessory (I), and
make sure the steering wheel turns
f reely bef ore you begin towing.

The exhaust emissions controls
include f our systems: PGM-FI,
Ignition Timing Control, Exhaust
Gas Recirculation and Three Way
Catalytic Converter. These four
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 f rom the crankcase and
evaporative emissions control
systems.The emissions control systems are
covered by warranties separate from
the rest of your car. Read your
warranty manual for more inf orma-
tion.
The PGM-FI System uses sequential
multiport f uel injection.
It has three subsystems: Air Intake,
Engine Control, and Fuel Control.
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 Exhaust Gas Recirculation
(EGR) system takes some of the
exhaust gas and routes it back into
the intake manif old. Adding exhaust
gas to the air/f uel mixture reduces
the amount of NOx produced when
the f uel is burned.
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 Honda replacement parts or
their equivalent f or repairs. Using
lower quality parts may increase the
emissions f rom your car.
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.
