2004 HONDA CIVIC check engine

Saf ely pull to the side of the road.
Put the transmission in Neutral or
Park, and set the parking brake.
Turn of f all accessories, and turn
on the hazard light.
If you see steam and/or spray
coming f rom under the hood, turn
of f the engine. Wait until you see
no more signs of steam or spray,
then open the hood.If you do not see steam or spray,
leave the engine running and
watch the temperature gauge. If
the high heat is due to overloading,
the engine should start to cool
down almost immediately. If it
does, wait until the temperature
gauge comes down to the midpoint,
then continue driving.
If the temperature gauge stays at
the red mark, turn of f the engine.Look f or any obvious coolant leaks,
such as a split radiator hose.
Everything is still extremely hot,
so use caution. If you f ind a leak, it
must be repaired bef ore you
continue driving (see
on page ).
If you don’t f ind an obvious leak,
check the coolant level in the
radiator reserve tank. Add coolant
if the level is below the MIN mark.

If there was no coolant in the
reserve tank, you may need to add
coolant to the radiator. Let the
engine cool down until the pointer
reaches the middle of the tempera-
ture gauge, or lower, bef ore check-
ing the radiator.Using gloves or a large heavy
cloth, turn the radiator cap
counterclockwise without pushing
down to the first stop. After the
pressure releases, push down on
the cap and turn it until it comes
off.
Start the engine and set the
temperature control dial to
maximum. Add coolant to the
radiator up to the base of the f iller
neck. If you do not have the
proper coolant mixture available,
you can add plain water.
Remember to have the cooling
system drained and ref illed with
the proper mixture as soon as you
can.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
on page ).
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.

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.

This light should never
come on when the engine is
running. If it starts f lashing
or stays on, the oil pressure has
dropped very low or lost pressure.
Serious engine damage is possible
and you should take immediate
action. Saf ely pull of f the road, and shut
of f the engine. Turn on the hazard
warning indicators.
Let the vehicle sit f or a minute.
Open the hood, and check the oil
level (see page ). An engine
very low on oil can lose pressure
during cornering and other driving
maneuvers.
If necessary, add oil to bring the
level back to the full mark on the
dipstick (see page ).
Start the engine, and watch the oil
pressure indicator. If it does not go
out within ten seconds, turn of f
the engine. There is a mechanical
problem that needs to be repaired
bef ore you can continue driving.
(See on page
). If the charging system
indicator comes on brightly
when the engine is running,
the battery is not being charged.
Immediately turn of f all electrical
accessories. Try not to use other
electrically operated controls such as
the power windows. Keep the engine
running; starting the engine will
discharge the battery rapidly.
Go to a service station or garage
where you can get technical
assistance.

If the indicator remains on, or the
f uel cap was not loose or missing,
have the vehicle checked by the
dealer as soon as possible.
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 battery has been
disconnected or gone dead, these
codes are erased. If takes at least
three days of driving under various
conditions to set the codes again.
To check if they are set, turn the
ignition to ON (II), without starting
the engine. The Malf unction
Indicator Lamp will come on f or 20
seconds. If it then goes of f , the
readiness codes are set. If it blinks 5
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.
Refer to State Emissions Testing for
more inf ormation (see page ).
If the indicator comes on
while driving, it means one
of the engine’s emission
control systems may have a problem.
Even though you may f eel no
dif f erence in your vehicle’s
perf ormance, continued operation
may cause serious damage.
If you have recently ref ueled your
vehicle, the indicator coming on
could be a loose or missing f uel f ill
cap. Tighten the cap until it clicks at
least three times. Tightening the cap
will not turn the indicator turn of f
immediately; it takes at least three
days of normal driving. 205
