Malfunction Indicator Lamp

Check Engine Light
This system is called OBD II (On-Board
Diagnostics-Second Generation) and is intended
to assure that emissions are at acceptable
levels for the life of the vehicle, helping to produce
a cleaner environment.
208
Your vehicle has a
computer which
monitors operation of the
fuel, ignition, and
emission control
systems.
The check engine light comes on to indicate that
there is a problem and service is required.
Malfunctions often will be indicated by the system
before any problem is apparent. This may
prevent more serious damage to your vehicle.
This system is also designed to assist your service
technician in correctly diagnosing any malfunction.
Notice: If you keep driving your vehicle
with this light on, after awhile, the emission
controls might not work as well, your vehicle's
fuel economy might not be as good, and the
engine might not run as smoothly. This
could lead to costly repairs that might not be
covered by your warranty.
Notice: Modifications made to the engine,
transmission, exhaust, intake, or fuel system
of your vehicle or the replacement of the
original tires with other than those of the same
Tire Performance Criteria (TPC) can affect
your vehicle's emission controls and can cause
this light to come on. Modifications to these
systems could lead to costly repairs not
covered by your warranty. This could also
result in a failure to pass a required Emission
Inspection/Maintenance test. See Accessories
and Modifications on page 347.
