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 5-8. 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 5-5. 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.
