The Check engine indicator light

illuminates when the ignition is first

turned to the ON/RUN position to

check the bulb. If it comes on after

the engine is started, one of the

engine's emission control systems

may be malfunctioning. The light

may illuminate without a

driveability concern being noted.

The vehicle will usually be driveable

and will not require towing.

What you should do if the check
engine light illuminates

Light turns on solid:
This means that the OBD II system

has detected a malfunction.
Temporary malfunctions may cause

your Check engine light to

illuminate. Examples are:

1. The vehicle has run out of fuel.

(The engine may misfire or run

poorly).

2. Poor fuel quality or water in the

fuel.

3. The fuel cap may not have been

properly installed and securely

tightened.

These temporary malfunctions can

be corrected by filling the fuel tank

with good quality fuel and/or

properly installing and securely

tightening the gas cap. After three

drive cycles without these or any

other temporary malfunctions

present, the Check engine light

should turn off. (A driving cycle

consists of a cold engine startup

followed by mixed city/highway

driving). No additional vehicle

service is required.
