2007 HONDA CIVIC HYBRID check engine

Check the f luid level with the engine
at normal operating temperature.Remove the dipstick (yellow loop)
f rom the transmission, and wipe it
with a clean cloth.
Insert the dipstick all the way into
the transmission securely as
shown in the illustration.
Remove the dipstick and check
the f luid level. It should be
between the upper and lower
marks within the HOT range.If the level is below the lower
mark, add f luid into the dipstick
hole to bring it to the level
between the upper and lower
marks.
Pour the f luid slowly and caref ully
so you do not spill any. Clean up
any spill immediately; it could
damage components in the engine
compartment.
Always use Honda CVT Fluid
(Continuously Variable
Transmission f luid).
Park the vehicle on level ground.
Start the engine and let it run until
the radiator fan comes on, then
shut of f the engine. For accurate
results, wait about 60 seconds
bef ore going to step 2, but don’t
wait longer than 90 seconds. 3.

Diagnosing why the engine won’t
start falls into two areas, depending
on what you hear when you turn the
ignition switch to the START (III)
position:
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 12 volt battery and terminal
connections (see page ). You
canthentryjumpstartingthe
vehicle from a booster battery
(see page ).
You
hear nothing, or almost
nothing. The engine’s starter
motor does not operate at all, or
operates very slowly.
You can hear the starter motor
operating normally, or the starter
motor sounds like it is spinning
faster than normal, but the engine
does not start up and run. Wh
en you turn the ignition switch to
the START (III) position, you do not
hear the normal noise of the engine
trying to start. You may hear a
clicking sound, a series of clicks, or
nothing at all.
Check these things:
Check the transmission interlock.
The transmission must be in Park
or neutral or the starter will not
operate. 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 .
Turn the ignition switch to the ON
(II) position. Turn on the
headlights, and check their
brightness. If the headlights are
very dim or do not come on at all,
the battery is discharged. See
on page . 223 223212237

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 ).
Are you using the proper starting
procedure? Refer to
on 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. Ifyoufindnothingwrong,youwill
need
a qualified technician to find
the problem. See
on page .
Do
you have fuel? Check the fuel
gauge; the low fuel indicator may
not be working.
There may be an electrical
problem, such as no power to the
fuel pump. Check all the fuses
(see page ).

µStart the vehicle. If the starter
motor still operates slowly, check
that the jumper cables have good
metal-to-metal contact.
Keep the ends of the jumper cables
away from each other and any metal
on the vehicle until everything is
disconnected. Otherwise, you may
cause an electrical short.
If the booster battery is in another
vehicle, have an assistant start
that vehicle and run it at a fast idle. Once your vehicle is running,
disconnect the negative cable f rom
your vehicle, then f rom the
booster battery. Disconnect the
positive cable f rom your vehicle,
then from the booster battery.
If your vehicle’s 12 volt battery is
disconnected or goes dead, the IMA
battery level gauge reading will not
be correct the next time you turn the
ignition switch to the ON (II)
position. It will show less than the
actual level temporarily. It will show
the correct level af ter you drive f or
at least 30 minutes.
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. 7. 6.

Start the engine, and set the
interior temperature to maximum.
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.
Put the radiator cap back on
tightl y. Run the engine, and check
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.
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 don’t find an obvious leak,
check the coolant level in the
radiator reserve tank (see page
). 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 reading
reaches the middle of the
temperature gauge or lower
bef ore checking the radiator. 8. 9.

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.

If necessary, add oil to bring the
level back to the full mark on the
dipstick (see page ).
This
indicator should never
come on when the engine is
running. If it starts flashing
or stays on, the oil pressure has
dropped very low or lost pressure.
Serious engine damage is possible,
and you should take immediate
action. The
engine running generates the oil
pressure. When the Auto Idle Stop is
acti vated, the engine is stopped, the
oil pressu re is dropped, and the low
oil pressu re indicator does not come
on.
Safely
pull off the road, and shut
off the engine. Turn on the hazard
warning lights.
Let the vehicle sit for a minute.
Op en the hood, and check the oil
level (see page ). An engine
very low on oil can lose pressure
during cornering and other driving
maneuvers.
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 m echanical
problem that needs to be repaired
bef ore you can continue driving
(see on page
).

Running the engine with low oil
pressure can cause serious mechanical
damage almost immediately. Turn of f
the engine as soon as you can saf ely get
the vehicle stopped.

If the indicator comes on repeatedly,
even though it may turn off as you
continue driving, have your vehicle
checked by your dealer as soon as
possible.
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 damage. If
the battery in your vehicle 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 five 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.
If
you have recently refueled your
vehicle, the indicator coming on
could be due to a loose or missing
fuel 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 at least three
days of normal driving. 151

If you keep driving with the

not be covered by your vehicle’s
warranties. This indicator may also
