2001 HONDA ODYSSEY check engine

This indicator should light when the
ignition switch is ON (II), and go out
af ter the engine starts. It should
never come on when the engine is
running. If it starts f lashing, it
indicates that the oil pressure
dropped very low f or 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.Saf ely pull of f the road and shut
of f the engine. Turn on the hazard
warning indicators.
If necessary, add oil to bring the
level back to the full mark on the
dipstick (see page ).
Let the vehicle sit f or a minute.
Open the hood and check the oil
level (see page ). Although oil
levelandoilpressurearenot
directly connected, an engine that
is very low on oil can lose pressure
during cornering and other driving
maneuvers. Start the engine and watch the oil
pressure indicator. If the light
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 .)

LLOOWWOOIILLPPRREESSSSUURREEIINNDDIICCAATTOORR 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 remains on past three
driving trips, or the f uel cap was not
loose or missing, have the vehicle
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.
Youshouldalsohavethedealer
inspect your vehicle if this indicator
comes on repeatedly, even though it
may turn of f as you continue driving.This indicator may also come on
along with the ‘‘D ’’ indicator.
This indicator should light when the
ignition switch is ON (II), and go out
af ter 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 f eel no dif f erence in
your vehicle’s perf ormance, it can
reduce your f uel economy and cause
your vehicle to put out excessive
emissions. Continued operation may
cause serious damage. If you have recently ref ueled your
vehicle, the cause of this indicator
coming on could be a loose or
missing f uel f ill 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 of f
immediately; it takes at least three
driving trips.

Malf unction Indicator L amp

MMAALLFFUUNNCCTTIIOONNIINNDDIICCAATTOORRLLAAMMPP If you keep driving with the
malf unction indicator lamp on, you can
damage your vehicle’s emissions
controls and engine. Those repairs may
not be covered by your vehicle’s
warranties.

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 vehicele’s battery has been
disconnected or gone dead, these
codes are erased. It takes several
days of driving under various
conditions to set the codes again.If possible, do not take your car f or a
state emissions test until the
readiness codes are set. To check if
they are set, turn the ignition ON (II),
but do not start 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. See State
Emissions Testing on pages and
