Did
you recently put fuel into your vehicle?
If so, reinstall the fuel cap, making s111-e to fully install
the cap. The diagnostic system can cleter~nine
if the fuel cap
has been left off
or improperly installed. A loose or
missing fuel cap
will allow fuel to evaporate into the
atmosphere.
A few driving trips with the cap properly
installed 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.
Have you recently changed brands of fuel?
I1 so, be sure to fuel your vehicle with cpality fuel (see
“Fuel”
in the Index). Poor fuel quality will cause your
engine not to
r11n as e,fficiently as designed. You may
notice this
as stalling after start-up, stalling when you put
the vehicle
into gear, mistlring, hesitation on acceleration
or
stumbling on acceleration. (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 one or more of these conditions,
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
problcnls that may have developed.
