2001 HONDA ACCORD SEDAN check engine

Air Conditioning System
Optional for U.S. DX model

Your car's air conditioning is a sealed system. Any major maintenance,
such as recharging, should be done
by a qualified mechanic. You can do a couple of things to make sure the
air conditioning works efficiently.
Periodically check the engine's
radiator and air conditioning condenser for leaves, insects, and
dirt stuck to the front surface. These
block the air flow and reduce cooling efficiency. Use a light spray from a
hose or a soft brush to remove them.

The condenser and radiator fins bend

easily. Only use a low-pressure spray

or soft-bristle brush to clean them.
AIR CONDITIONING CONDENSER

Run the air conditioning at least once
a week during the cold weather
months. Run it for at least ten
minutes while you are driving at a steady speed with the engine at
normal operating temperature. This
circulates the lubricating oil con-
tained in the refrigerant.
If the air conditioning does not get as

cold as before, have your dealer

check the system. Recharge the

system with Refrigerant HFC-134a

(R-134a). (See Specifications on page 328.)

Whenever you have the air conditioning

system serviced, make sure the service

facility uses a refrigerant recycling
system. This system captures the
refrigerant for reuse. Releasing
refrigerant into the atmosphere can

damage the environment.

Taking Care of the Unexpected

If Your Engine Won't Start
Nothing Happens or the Starter Motor Operates Very Slowly
When you turn the ignition switch to START (III), you do not hear the
normal noise of the engine trying tostart. You may hear a clicking sound
or series of clicks, or nothing at all.
Check these things:
Your car has the ImmobilizerSystem. You should use a
properly-coded master or valet key
to start the engine (see page 57).
A key that is not properly coded will cause the immobilizer systemindicator in the dash panel to blink
rapidly. Check the transmission interlock.
If you have a manual transmission,
the clutch pedal must be pushed all the way to the floor or the
starter will not operate. With an
automatic transmission, it must be
in Park or Neutral.
Turn the ignition switch to ON (II).
Turn on the headlights and check their brightness. If the headlightsare very dim or don't light at all,
the battery is discharged. See
Jump Starting on page 304. Turn the ignition switch to START
(III). If the headlights do not dim,
check the condition of the fuses. If
the fuses are OK, there is proba-
bly something wrong with the electrical circuit for the ignitionswitch or starter motor. You will
need a qualified technician to
determine the problem. (See
Emergency Towing on page 320 .)
If the headlights dim noticeably or
go out when you try to start the engine, either the battery is dis-
charged or the connections arecorroded. Check the condition of
the battery and terminal connec-
tions (see page 260). You can
then try jump starting the car from a booster battery (see page 304).

Taking Care of the Unexpected

If Your Engine Won't Start, Jump Starting
The Starter Operates Normally In this case, the starter motor's
speed sounds normal, or even faster
than normal, when you turn the
ignition switch to START (III), but
the engine does not run.
Are you using the proper startingprocedure? Refer to Starting the
Engine on page 193 .Do you have fuel? Turn the
ignition switch to ON (II) for a
minute and watch the fuel gauge.
The low fuel level warning light may not be working, so you werenot reminded to fill the tank.
There may be an electrical problem, such as no power to the
fuel pump. Check all the fuses (see page 315).
If you find nothing wrong, you will
need a qualified technician to find
the problem. See Emergency
Towing on page 320 . Jump Starting
If your car's battery has run down,
you may be able to start the engine
by using a booster battery. Although
this seems like a simple procedure,
you should take several precautions.
You cannot start a Honda with an automatic transmission by pushing
or pulling it. To jump start your car, follow these
directions closely:
1. Open the hood and check the physical condition of the battery(see page 260). In very cold
weather, check the condition of the electrolyte. If it seems slushy
or like ice, do not try jump starting
until it thaws.

If a battery sits in extreme cold, the electrolyte inside can freeze.
Attempting to jump start with a frozen battery can cause it to rupture.

2. Turn off all the electrical acces- sories: climate control, stereo
system, lights, etc.
Put the transmission in Neutral or
Park and set the parking brake.

Taking Care of the Unexpected
A battery can explode if you do

not follow the correct procedure,
seriously injuring anyone nearby.
Keep all sparks, open flames,
and smoking materials away
from the battery.
NOTICE

If Your Engine Overheats
4. If the temperature gauge stays at the red mark, turn off the engine.
5. Wait until you see no more signs of steam or spray, then open the

hood.

6. Look for any obvious coolant leaks, such as a split radiator hose.
Everything is still extremely hot,so use caution. If you find a leak, it
must be repaired before you
continue driving (see Emergency
Towing on page 320).
7. If you don't find an obvious leak, check the coolant level in the
radiator reserve tank (see page 184). If the level is below the
MIN mark, add coolant to halfway
between the MIN and MAX marks.
8. If there was no coolant in the reserve tank, you may also have to
add coolant to the radiator. Let the
engine cool down until the pointer reaches the middle of the tempera-
ture gauge, or lower, before check- ing the radiator.
9. Using gloves or a large heavy cloth, turn the radiator cap
counterclockwise, without pushing
down, to the first stop. This
releases any remaining pressure in
the cooling system. After the
pressure releases, push down on
the cap and turn it until it comes
off. 10. Start the engine and set the
temperature control dial tomaximum (climate control to
FULL AUTO at 90°F/32°C). Add
coolant to the radiator up to the
base of the filler neck. If you do
not have the proper coolant mixture available, you can add
plain water. Remember to have
the cooling system drained and refilled with the proper mixture as
soon as you can.

11. Put the radiator cap back on tightly. Run the engine and watch
the temperature gauge. If it goes
back to the red mark, the engine
needs repair. (See Emergency
Towing on page 320.)
12. If the temperature stays normal, check the coolant level in the
radiator reserve tank. If it has
gone down, add coolant to the MAX mark. Put the cap back on

tightly.

Taking Care of the Unexpected
Removing the radiator cap

while the engine is hot can

cause the coolant to spray out, seriously scalding you.

Always let the engine and radiator cool down before

removing the radiator cap.

Low Oil Pressure Indicator

LOW OIL PRESSURE INDICATOR

This indicator should light when the ignition switch is ON (II), and go out
after the engine starts. It should
never come on when the engine is
running. If it starts flashing, it
indicates that the oil pressure dropped very low for a moment, then
recovered. If the indicator stays on
with the engine running, it shows that the engine has lost oil pressure
and serious engine damage is
possible. In either case, you should
take immediate action.
Running the engine with low oil
pressure can cause serious mechanical damage almost immediately. Turn offthe engine as soon as you can safely get
the car stopped.

1. Safely pull off the road and shut off the engine. Turn on the hazard
warning indicators.
2. Let the car sit for a minute. Open the hood and check the oil level(see page 182). Although oil level
and oil pressure are not directly
connected, an engine that is very
low on oil can lose pressure during
cornering and other driving

maneuvers.

3. If necessary, add oil to bring the level back to the full mark on thedipstick (see page 234). 4. Start the engine and watch the oil
pressure indicator. If the lightdoes not go out within ten seconds,
turn off the engine. There is a mechanical problem that needs to
be repaired before you can continue driving. (See Emergency
Towing on page 320.)

NOTICE

Malfunction Indicator Lamp

MALFUNCTION INDICATOR LAMP

(For
L4-
LEV)

This indicator comes on for a few 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 feel no difference in your car's performance, it can reduce
your fuel economy and cause your car to put out excessive emissions.
Continued operation may cause
serious damage.
(For V6 and L4- ULEV)

This indicator should light when the ignition switch is ON (II), and go out
after the engine starts. 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 feel no difference in

your car's performance, it can
reduce your fuel economy and cause
your car to put out excessive
emissions. Continued operation may

cause serious damage.

If you have recently refueled your

car, the cause of this indicator
coming on could be a loose or

missing fuel fill 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 off

immediately; it takes at least three
driving trips. If the indicator remains on past three
driving trips, or the fuel 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.
You should also have the dealer inspect your car if this indicator
comes on repeatedly, even though it
may turn off as you continue driving.

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

Malfunction Indicator Lamp

Readiness Codes
Your car has certain "readiness codes" that are part of the on-board
diagnostics for 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 car's battery has been
disconnected or gone dead, these
codes are erased. It takes severaldays of driving under various
conditions to set the codes again.
If possible, do not take your car for a
state emissions test until the
readiness codes are set. See State
Emissions Testing on page 336.
(For V6 and L4-ULEV)
To check if they are set, turn the ignition ON (II), but do not start
the engine. The Malfunction
Indicator Lamp will come on for
20 seconds. If it then goes off,
the readiness codes are set. If it blinks 5 times, the readiness
codes are not set. See State
Emissions Testing on pages 301 and
302.
