Malfunction Indicator Lamp

Check Engine Light

Your vehicle has a

computer which monitors

operation of the fuel,

ignition, and emission

control systems.

This system is called OBD II (On-Board

Diagnostics-Second Generation) and is intended to

make sure that emissions are at acceptable levels for

the life of the vehicle, helping to produce a cleaner

environment. The check engine light comes on to

indicate that there is a problem and service is required.

Malfunctions often will be indicated by the system

before any problem is apparent. This can prevent more

serious damage to your vehicle. This system is also

designed to assist your service technician in correctly

diagnosing any malfunction.

Notice:

If you keep driving your vehicle with this

light on, after a while, the emission controls

might not work as well, your vehicle’s fuel economy

might not be as good, and the engine might not

run as smoothly. This could lead to costly repairs

that might not be covered by your warranty.

Notice:

Modifications made to the engine,

transmission, exhaust, intake, or fuel system of

your vehicle or the replacement of the original tires

with other than those of the same Tire Performance

Criteria (TPC) can affect your vehicle’s emission

controls and can cause this light to come on.

Modifications to these systems could lead to costly

repairs not covered by your warranty. This could

also result in a failure to pass a required Emission

Inspection/Maintenance test. See

Accessories

and Modifications on page 5-3

This light should come on, as a check to show you it is

working, when the ignition is on and the engine is

not running. If the light does not come on, have it

repaired. This light will also come on during a

malfunction in one of two ways:

•

Light Flashing

— A misfire condition has been

detected. A misfire increases vehicle emissions

and could damage the emission control system on

your vehicle. Diagnosis and service might be

required.

•

Light On Steady

— An emission control system

malfunction has been detected on your vehicle.

Diagnosis and service might be required.
