If the Light Is On Steady
You might be able to correct the emission system
malfunction by considering the following:
Did you recently put fuel into your vehicle?
If so, reinstall the fuel cap, making sure to fully
install the cap. See Filling the Tank on page 381.
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.
Did you just drive through a deep puddle of water?
If so, your 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.
Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel.
See Gasoline Octane on page 379. Poor fuel
quality causes the engine not to run as efficiently
as designed. You might notice this as stalling
after start-up, stalling when you put the vehicle into
gear, misfiring, hesitation on acceleration, or
stumbling on acceleration — these conditions
might 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, your dealer/retailer can check the vehicle.
Your dealer/retailer has the proper test equipment
and diagnostic tools to fix any mechanical or
electrical problems that might have developed.
