2004 HONDA INSIGHT sensor

Your airbag system includes:Two SRS (Supplemental Restraint
System) airbags. The driver’s
airbag is stored in the center of
the steering wheel; the passenger’s
airbag is stored in the dashboard.
Both are marked ‘‘SRS AIRBAG.’’
Sensors that can detect a
moderate to severe frontal
collision. A sophisticated electronic system
that continually monitors and
records inf ormation about the
sensors, the control unit, the
airbag activators, and driver and
passenger seat belt use when the
ignition is in the ON (II) position.
An indicator on the instrument
panel that alerts you to a possible
problem with your airbags (see
page ).
Emergency backup power in case
your vehicle’s electrical system is
disconnected in a crash.
If you ever have a moderate to
severe f rontal collision, sensors will
detect the vehicle’s rapid
deceleration. If the rate of
deceleration is high enough, the
control unit will instantly inf late the
driver’s and passenger’s airbags.
Automatic seat belt tensioners
that tighten the seat belts during a
moderate to severe frontal
collision.

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 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 emissions control systems are
covered by warranties separate from
the rest of your vehicle. Read your
warranty manual f or more informa-
tion.
