On-Board Diagnostics monitors the components of your emission
control system. Each monitored component in your engine system
has been assigned a code . In case of a malfunction, the component
will be identified and the fault stored as a code in the control
module memory .
The MIL 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 properly closed
