2006 HONDA ACCORD COUPE check engine

Ifyoufindnothingwrong,youwill
need a qualified technician to find
the problem. Seeon page .
There may be an electrical
problem, such as no power to the
fuel pump. Check all the fuses
(see page ). Do you have fuel? Check the fuel
gauge; the low fuel indicator m ay
not be working. Are you using a properly coded
key? An improperly coded key will
cause the immobilizer system
indicator in the instrument panel
to blink rapidly (see page ).
In this case, the starter motor’s
speed sounds normal, or even faster
than normal, when you turn the
ignition switch to the START (III)
position, but the engine does not run.
Are you using the proper starting
procedure? Refer to on page .
Turn the ignition switch to the
START (III) position. If the
headlights do not dim, check the
condition of the fuses. If the fuses
areOK,thereisprobably
something wrong with the
electrical circuit for the ignition
switch or starter motor. You will
need a qualified technician to
determine the problem (see
on page ).
If the headlights dim noticeably or
go out when you try to start the
engine, either the battery is
discharged or the connections are
corroded. Check the condition of the
battery and terminal connections
(see page ). You can then try
jump starting the vehicle from a
booster battery (see page ). 59

Start the vehicle. If the starter
motor still operates slowly, check
that the jumper cables have good
metal-to-metal contact.
If the booster battery is in another
vehicle, have an assistant start
that vehicle and run it at a fast idle. Connect the second jumper cable
to the negative ( ) terminal on
the booster battery. Connect the
other end to the grounding strap
as shown. Do not connect this
jumper cable to any other part of
the engine.
Connect one jumper cable to the
positive ( ) terminal on your
vehicle’s battery. Connect the
other end to the positive ( )
terminal on the booster battery.

Put the radiator cap back on
tightl y. Run the engine, and watch
the temperatu re 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.
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. 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
temperature gauge or lower
befo re checking the radiato r.
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 temperatu re
gauge comes down to the midpoint,
th en continue driving.
If the temperatu re gauge stays at
the red mark, turn off the engine.
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
on page ).
If you do not f ind an obvious leak,
check the coolant level in the
radiator reserve tank. Add coolant
if the level is below the MIN mark. Start the engine, and set the
temperature to maximum heat
(climate control to AUTO at
‘‘ ’’). 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.

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 indicator should never come on
when the engine is running. If it
starts flashing or stays on, the oil
pressu re has dropped very low or
lost pressure. Serious engine
damage is possible, and you should
take immediate action. Let
the vehicle sit for 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 10 seconds, turn off the
engine. There is a mechanical
problem that needs to be repaired
befo re 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.
Saf ely pull of f the road and shut
of f the engine. Turn on the hazard
warning lights.

If the indicator comes on
while driving, it means one
of the engine’s emissions control
systems may have a problem. Even
though you may feel no difference in
your vehicle’s performance, it can
reduce your fuel economy and cause
increased emissions. Continued
operation may cause serious damag e. If
your vehicle battery has been
disconnected or gone dead, these
codes are erased. It takes at least
three days of driving under various
conditions to set the codes again.
To check if they are set, turn the
ignition switch to the ON (II)
position without starting 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. If possible, do not
take your vehicle for a state
emissions test until the readiness
codes are set. Refer to
for more
info rmation (see page ).
Your vehicle 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.
This
indicator may also come on with
the ‘‘D’’ indicator.
If
the indicator comes on repeatedly,
even though it may turn off as you
continue driving, have the vehicle
checked by the dealer as soon as
possible.
If you have recently refueled your
vehicle, the indicator coming on
could be due to a loose or missing
fu el fill cap. You will also see a
‘‘CHECK FUEL CAP’’ message on
the information display. Tighten the
cap until it clicks at least once (see
page ). Tightening the cap will
not turn the indicator of f
immediately; it takes several days
of normal driving. 300
