FORD 2008 Crown Victoria - Manual (Page 11)

Service Engine Soon: The Service
Engine Soon indicator light
illuminates when the ignition is first
turned to the ON position to check
the bulb and to indicate whether the vehicle is ready for
Inspection/Maintenance (I/M) testing. Normally, the
ЉService engine soonЉ
light will stay on until the engine is cranked, then turn itself off if no
malfunctions are present. However, if after 15 seconds the
ЉService
engine soon
Љ light blinks eight times, it means that the vehicle is not
ready for I/M testing. See the Readiness for Inspection/Maintenance
(I/M) testing in the Maintenance and Specifications chapter.
Solid illumination after the engine is started indicates the On Board
Diagnostics System (OBD-II) has detected a malfunction. Refer to On
board diagnostics (OBD-II) in the Maintenance and Specifications
chapter. If the light is blinking, engine misfire is occurring which could
damage your catalytic converter. Drive in a moderate fashion (avoid
heavy acceleration and deceleration) and have your vehicle serviced
immediately by your authorized dealer.
Under engine misfire conditions, excessive exhaust temperatures
could damage the catalytic converter, the fuel system, interior
floor coverings or other vehicle components, possibly causing a fire.
Powertrain malfunction
indicator (if equipped):
Illuminates when a powertrain fault
has been detected. Contact your
authorized dealer as soon as possible.
Check fuel cap (if equipped):
Illuminates when the fuel cap may
not be properly installed. Continued
driving with this light on may cause
the Service engine soon warning
light to come on. Refer to Fuel
filler cap in the Maintenance and Specifications chapter.
