2007 HONDA S2000 check 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
the temperatu re gauge stays at
the red mark, turn off the engine.
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,
th en continue driving.
If
you see steam and/or spray
coming from under the hood, turn
off the engine. Wait until you see
no more signs of steam or spray,
th en open the hood.
Safely
pull to the side of the road.
Put the transmission in neutral,
and set the parking brake. Turn
off the all accessories, and turn on
the hazard warning indicators.
If you don’t find an obvious leak,
check the coolant level in the
radiator reserve tank. Add coolant
if the level is below the MIN mark
(see on
page ).

Steam and spray from an
overheated engine can
seriously scald you.
Do not open the hood if steam
is coming out.

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
befo re checking the radiato r. 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. 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.
Start the engine, and set the
temperature control dial to
maximum heat. 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.

Safely pull off the road, and shut
off the engine. Turn on the hazard
warning indicators.
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.
If necessary, add oil to bring the
level back to the full mark on the
dipsti ck (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.
This indicator 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. 1.

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 go off as you
continue driving, have your vehicle
checked by a dealer as soon as
possible.
If
this 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.
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. 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. Ref er to for more
inf ormation (see page ).
If you have recently ref ueled your
vehicle, the indicator coming on
could be due to a loose or missing
f uel f ill cap. You will also see a
‘‘CHECK FUEL CAP’’ message on
the inf ormation display. Tighten the
cap until it clicks at least once.
Tightening the cap will not turn the
indicator of f immediately; it can take
several days of normal driving. If your vehicle’s battery has been
disconnected or gone dead, these
codes are erased. It can take several
days of driving under various
conditions to set the codes again.
