Malfunction Indicator Lamp

Check Engine Light

A computer system called OBD II (On-Board

Diagnostics-Second Generation) monitors operation of

the fuel, ignition, and emission control systems. It makes

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 an OBD II

problem and service

is required.

Malfunctions often are 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 replacement tires that do not

match your vehicle’s original tires 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.

When the ignition is turned to ON/RUN, this light comes

on and should go out after a few seconds as a check

to show it is working. If the light does not come on, have

it repaired. This light also comes 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.
