2006 HONDA ACCORD ignition

Diagnosing why the engine won’t
start f alls into two areas, depending
on what you hear when you turn the
ignition switch to the START (III)
position:When 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 or series of clicks, or
nothing at all.
Store the wheel cover or center
cap in the trunk. Make sure it does
not get scratched or damaged. You can hear the starter motor operating normally, or the starter
motor sounds like it is spinning
f aster than normal, but the engine
does not start up and run.
You hear nothing, or almost
nothing. The engine’s starter
motor does not operate at all, or
operates very slowly.
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. Seeon page .
Check the transmission interlock.
If you have a manual transmission,
the clutch pedal must be pushed
all the way to the f loor or the
starter will not operate. With an
automatic transmission, it must be
in Park or neutral.
Check these things:

Store the wheel, jack, and tools
securely before driving.

In this case, the starter motor’s
speed sounds normal, or even f aster
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? Ref er to on page .
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 ). Do you have f uel? Check the f uel
gauge; the low f uel indicator may
not be working.
There may be an electrical
problem, such as no power to the
f uel pump. Check all the f uses
(see page ).
If the headlights dim noticeably or
go out when you try to start the
engine, either the battery is dis-
charged or the connections are
corroded. Check the condition of
the battery connections (see page ). You can then try jump
starting the vehicle from a booster
battery (see page ).
Turn the ignition switch to the
START (III) position. If the
headlights do not dim, check the
condition of the f uses. If the f uses
areOK,thereisprobably
something wrong with the
electrical circuit for the ignition
switch or starter motor. You will
need a qualif ied mechanic to
determine the problem (see
on page ). If youfindnothingwrong,youwill
need a qualif ied mechanic to f ind the
problem. See
on page .

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.If your vehicle’s 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.
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
or replace it. Tightening the cap will
not make the indicator turn of f
immediately; it takes at least three
days of normal driving.
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.To check if they are set, turn the
ignition switch to the ON (II)
position, 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 f ive 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 ). 277

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. This indicator may also
come on with the ‘‘D’’ indicator.

With the f ront wheels on the ground,
it is best to tow the vehicle no farther
than 50 miles (80 km), and keep the
speedbelow35mph(55km/h).If you decide to tow your vehicle
with all f our wheels on the ground,
make sure you use a properly-
designed and attached tow bar.
Prepare the vehicle for towing as
described above, and leave the
ignition switch in Accessory (I) so
the steering wheel does not lock.
Make sure the radio and any items
plugged into the accessory power
socket are turned of f so they do not
rundownthebattery.
If your vehicle is equipped with a
f ront spoiler, remove it bef ore
towing so it is not damaged.

The steering system can be damaged if
the steering wheel is locked. Leave the
ignition switch in ACCESSORY (I), and
make sure the steering wheel turns
f reely bef ore you begin towing.
Trying to lif t or tow your vehicle by the
bumpers will cause serious damage.
The bumpers are not designed to
support the vehicle’s weight.

the f use box lid, pull it toward you
and take it out of its hinges.The under-hood f use box is located
near the back of the engine compart-
ment on the driver’s side. To open it,

f use box lid, which f use or f uses
control that component. Check those
f uses f irst, but check all the f uses
bef ore deciding that a blown f use is
not the cause. Replace any blown
f uses and check if the device works.
Turn the ignition switch to the

The exhaust emissions controls
include f our systems: PGM-FI,
ignition timing control, exhaust gas
recirculation, and three way catalytic
converter. These f our systems work
together to control the engine’s
combustion and minimize the
amount of HC, CO, and NOx that
comes out the tailpipe. The exhaust
emissions control systems are
separate f rom the crankcase and
evaporative emissions control
systems.
The PGM-FI system uses sequential
multiport f uel injection. It has three
subsystems: air intake, engine
control, and f uel control. The
powertrain control module (PCM) in
automatic transmission vehicles or
the engine control module (ECM) in
manual transmission vehicles uses
various sensors to determine how
much air is going into the engine. Itthen controls how much f uel to inject
under all operating conditions. The emissions control systems are
designed and certif ied to work to-
gether in reducing emissions to
levels that comply with the Clean Air
Act. To make sure the emissions
remain low, you should use only new
Honda replacement parts or their
equivalent f or repairs. Using lower
qualitypartsmayincreasethe
emissions f rom your vehicle.
The emissions control systems are
covered by warranties separate f rom
the rest of your vehicle. Read your
warranty manual f or more inf orma-
tion.
The exhaust gas recirculation (EGR)
system takes some of the exhaust
gas and routes it back into the intake
manif old. Adding exhaust gas to the
air/f uel mixture reduces the amount
of NOx produced when the f uel is
burned.
This system constantly adjusts the
ignition timing, reducing the amount
of HC, CO, and NOx produced.
The three way catalytic converter is
in the exhaust system. Through
chemical reactions, it converts HC,
CO, and NOx in the engine’s exhaust
to carbon dioxide (CO ), nitrogen
(N ), and water vapor.
