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. See

“Filling Your Tank” in the Index. It will take a few

driving trips to turn the light off.

Have you recently changed brands of fuel?

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 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

problems that may have developed.

Emissions Inspection and Maintenance Programs

Some state/provincial and local governments have or

may begin programs to inspect the emission control

equipment on your vehicle. Failure to pass this

inspection could prevent you from getting a

vehicle registration.

Here are some things you need to know in order to help

your vehicle pass an inspection:

Your vehicle will not pass this inspection if the

SERVICE ENGINE SOON light is on or not

working properly.

Your vehicle will not pass this inspection if the OBD

(on

-board diagnostic) system determines that critical

emission control systems have not been completely

diagnosed by the system. The vehicle would be

considered not ready for inspection. This can happen if

you have recently replaced your battery or if your

battery has run down. The diagnostic system is designed

to evaluate critical emission control systems during

normal driving. This may take several days of routine

driving. If you have done this and your vehicle still does

not pass the inspection for lack of OBD system

readiness, see your dealer or qualified service center to

prepare the vehicle for inspection.
