OBD port FORD CROWN VICTORIA 1999 2.G Owners Manual

Check engine
Your vehicle is equipped with a
computer that monitors the engine's
emission control system. This system
is commonly known as the On Board
Diagnostics System (OBD II). This
OBD II system protects the environment by ensuring that your vehicle
continues to meet government emission standards. The OBD II system also
assists the service technician in properly servicing your vehicle.
TheCheck Engineindicator light illuminates when the ignition is first
turned to the ON 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 drivable 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 yourCheck Enginelight 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 driving cycles without these or any other
temporary malfunctions present, theCheck Enginelight should turn off.
(A driving cycle consists of a cold engine startup followed by mixed
city/highway driving.) No additional vehicle service is required.
If theCheck Enginelight remains on, have your vehicle serviced at the
first available opportunity.
Light is blinking:
Engine misfire is occurring which could damage your catalytic converter.
You should drive in a moderate fashion (avoid heavy acceleration and
deceleration) and have your vehicle serviced at the first available
opportunity.
