On-Board Diagnostics monitors the components
of your em ission control system. Each monitored
component in your eng ine system has been as­
signed a code. In case of a ma lfunction, the com­
ponent will be identified and the fault stored as a
code in the control module memory.
The MI L light may also illuminate if there is a
leak in the on -board fuel vapor recovery system.
If the light illuminates after a refueling, stop the
vehicle and make sure the fuel filler cap is prop­ erly closed (only vehicles with gasoline engine)
