If
the
Light
Is
On
Steady
Have you recently changed brands of fuel?
You
may be able to correct the emission system
malfunction by considering the following:
Did you just put fuel into your vehicle?
If
so,
reinstall the fuel cap, making sure to fully install
the cap. The diagnostic system can determine
if
the fuel
cap has been left
off
or improperly installed. This will
allow
fuel
to evaporate into
the
atmosphere.
A
few
driving trips should turn the light off.
Did you just drive through a deep puddle of water?
If
so,
your electrical system may be wet. The condition
will usually
be
corrected when the electrical system
dries out. A few driving trips should turn the light off.
Are you low on fuel?
As your engine starts to run out of fuel, your engine may
not
run
as efficiently
as
designed since small amounts of
air are sucked into the fuel line causing a misfire. The
system can detect this. Adding fuel should correct this
condition. Make sure
to
install the fuel cap properly. It
will take a few driving trips to turn the light off.
If
so,
be sure to fuel your vehicle with quality fuel (see
“Fuel” in the Index). Poor fuel quality will cause your
engine not to run as efficiently as designed. You may
notice this as stalling after start-up, stalling when
you
put the vehicle into gear, misfiring, hesitation on
acceleration or stumbling on accelerati,on. (These
conditions may go away once the engine is warmed up.)
This will be detected by the system and cause the light
to turn on.
If you experience this condition, change the fuel brand
you use. It will require at least one full tank of the
proper fuel to turn the light off.
If none of the above steps have made the light turn
off,
have your dealer or qualified service center check the
vehicle. Your dealer has the proper test equipment and
diagnostic tools to fix any mechanical or electrical
problems
that
may have developed.
