Lincoln Aviator: Catalytic Converter / On-Board Diagnostics (OBD-II)
Your vehicle has a computer known as the
on-board diagnostics system (OBD-II) that
monitors the engine’s emission control
system. The system protects the environment
by making sure that your vehicle continues
to meet government emission standards. The
OBD-II system also assists a service
technician in properly servicing your vehicle.
When the service engine soon
indicator illuminates, the OBD-II
system has detected a malfunction.
Temporary malfunctions may cause the
service engine soon indicator to illuminate.
Examples are:
- Your vehicle has run out of fuel—the
engine may misfire or run poorly.
- Poor fuel quality or water in the fuel—the
engine may misfire or run poorly.
- The fuel fill inlet may not have closed
properly.
- Driving through deep water—the
electrical system may be wet.
You can correct these temporary
malfunctions by filling the fuel tank with good
quality fuel, properly closing the fuel fill inlet
or letting the electrical system dry out. After
three driving cycles without these or any
other temporary malfunctions present, the
service engine soon indicator should stay off
the next time you start the engine. A driving
cycle consists of a cold engine startup
followed by mixed city and highway driving.
No additional vehicle service is required.
If the service engine soon indicator remains
on, have your vehicle serviced at the first
available opportunity. Although some
malfunctions detected by the OBD-II may not
have symptoms that are apparent, continued
driving with the service engine soon indicator
on can result in increased emissions, lower
fuel economy, reduced engine and
transmission smoothness and lead to more
costly repairs.
WARNING: Do not park, idle or drive
your vehicle on dry grass or other dry
ground cover. The emission system heats
up the engine compartment and exhaust
system, creating the risk of fire...
Some state and provincial and local
governments may have
Inspection/Maintenance (I/M) programs to
inspect the emission control equipment on
your vehicle...
