4-22 Instruments and Controls
Light On Steady: An emission
control system malfunction has
been detected on the vehicle.
Diagnosis and service might be
required.
An emission system malfunction
might be corrected.
. Make sure the fuel cap is fully
installed. See
Filling the Tank on
page 8 ‑ 48 . The diagnostic
system can determine if the
fuel cap has been left off or
improperly installed. A loose or
missing fuel cap allows fuel to
evaporate into the atmosphere.
A few driving trips with the cap
properly installed should turn the
light off.
. If the vehicle has been driven
through a deep puddle of water,
the vehicle's electrical system
might be wet. The condition is
usually corrected when the
electrical system dries out.
A few driving trips should turn
the light off.
. Make sure to fuel the vehicle
with quality fuel. Poor fuel quality
causes the engine not to run as
efficiently as designed and may
cause: stalling after start-up,
stalling when the vehicle is
changed into gear, misfiring,
hesitation on acceleration,
or stumbling on acceleration.
These conditions might go away
once the engine is warmed up.
If one or more of these
conditions occurs, change the
fuel brand used. It will require at
least one full tank of the proper
fuel to turn the light off.
See Gasoline Specifications on
page 8 ‑ 45 .
If none of the above have made
the light turn off, your dealer/retailer
can check the vehicle. The
dealer/retailer has the proper test
equipment and diagnostic tools to
fix any mechanical or electrical
problems that might have
developed.

governments have or might begin
programs to inspect the emission

inspection if the check engine
light is on with the engine
