2004 HONDA ELEMENT sensor

Your airbag system includes:Two SRS (Supplemental Restraint
System) f ront airbags. The driver’s
airbag is stored in the center of
the steering wheel; the f ront
passenger’sairbagisstoredinthe
dashboard. Both are marked ‘‘SRS
AIRBAG.’’
Automatic seat belt tensioners
(see page ).
Sensors that can detect a
moderate to severe frontal impact
or side impact in models equipped
with side airbags. A sophisticated electronic system
that continually monitors and
records inf ormation about the
sensors, the control unit, the
airbag activators, and driver and
frontpassengerseatbeltusewhen
the ignition is in the ON (II)
position.
On models equipped with side
airbags, one for the driver and one
f or a f ront passenger. The airbags
arestoredintheouteredgesof
the seat-backs. Both are marked
‘‘SIDE AIRBAG’’ (see page ). An indicator on the instrument
panel that alerts you to a possible
problem with your airbags,
sensors, or seat belt tensioners
(see page ).
If you ever have a moderate to
severe f rontal collision, sensors will
detect the vehicle’s rapid
deceleration.
Emergency backup power in case
your vehicle’s electrical system is
disconnected in a crash.
On models equipped with side
airbags, an indicator on the
dashboard that alerts you that the
passenger’s side airbag has been
turned of f (see page ). If the rate of deceleration is high
enough, the control unit will instantly
inf late the driver’s and f ront
passenger’s f ront airbags, at the time
and with the f orce needed.

If you ever have a moderate to
severe side impact, the sensors will
detect rapid deceleration and signal
the control unit to instantly inf late
either the driver’s or the passenger’s
side airbag.Only one airbag will deploy during a
side impact. If the impact is on the
passenger’s side, the passenger’s
side airbag will deploy even if there
is no passenger.
To get the best protection f rom the
side airbags, occupants should wear
their seat belts and sit upright and
well back in their seats.
The passenger’s side airbag has a
cutof f system designed to turn of f
the passenger’s side airbag if a child’s
head is in the airbag’s deployment
path (see page ).
If the side airbag of f indicator comes
on, have the passenger sit upright.
Once the passenger is out of the
deployment path of the side airbag,
the system will turn the airbag back
on and the indicator will go out
within a f ew seconds.
A f ront seat passenger should not
use a cushion or other object as a
backrest. It may prevent the cutof f
system f rom working properly.

The PGM-FI System uses sequential
multiport f uel injection.
It has three subsystems: Air Intake,
Engine Control, and Fuel Control.
The Engine Control Module (ECM)
or 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 operat-
ing conditions.
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 ), dinitrogen
(N ), and water vapor.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 exhaust emissions controls
include three systems: PGM-FI,
Ignition Timing Control, and Three
Way Catalytic Converter. These
three 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 from the crankcase and
evaporative emissions control
systems.
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.
