2005 HONDA PILOT ignition

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.
If the malf unction indicator lamp
comes on along with the ‘‘D’’
indicator, there is a problem in the
automatic transmission control
system.
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 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 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. If this indicator comes on
while driving, it means one
of the engine’s emission control
systems may have a problem. Even
though you may f eel no dif f erence in
your vehicle’s perf ormance,
continued operation may cause
serious damage. To check if they are set, turn the
ignition to ON (II), 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 f or a state emissions test
until the readiness codes are set.
Refer to
f or more inf ormation (see page ).

235
If you keep driving with the
malf unction indicator lamp on, you can
damage your vehicle’s emission
controls and engine. Those repairs may
not be covered by your vehicle’s
warranties.

If something electrical in your
vehicle stops working, the first thing
youshouldcheckforisablownfuse.
Determine f rom the chart on pagesand , or the diagram on the
fuse box lid, which fuse or fuses
control that device. The diagram f or
theinteriordriver’ssidefuseboxis
on the kick panel below the f use box.
Check those f uses f irst, but check all
the f uses bef ore deciding that a
blown f use is the cause. Replace any
blown f uses, and check if the device
works.
Turn the ignition switch to LOCK
(0). Make sure the headlights and
all other accessories are off.
Remove the cover f rom the f use
box. Check each of the large f uses in
the primary under-hood f use box
by looking through the top at the
wire inside. Remove the screws
with a Phillips-head screwdriver.
Check the smaller f uses in the
under-hood f use box and all the
fuses in the interior fuse boxes by
pulling out each f use with the f use
puller provided in the primary
under-hood f use box.
Look f or a burned wire inside the
f use. If it is burned, replace it with
one of the spare f uses of the same
rating or lower.

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)
uses various sensors to determine
how much air is going into the
engine. It then 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 from
the rest of your vehicle. Read your
warranty manual f or more informa-
tion.
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. This system constantly adjusts the
ignition timing, reducing the amount
of HC, CO, and NOx produced.
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.
