Which statement about the Malfunction Indicator Lamp (MIL) best reflects the material?

• A. The MIL indicates a fault in the emission control system, and the vehicle can be driven to end of shift.
• B. The MIL indicates a battery issue.
• C. The MIL indicates fuel level is low.
• D. The MIL indicates oil pressure is low.

Answer: (A)

The Malfunction Indicator Lamp is the check engine light that alerts you when the vehicle’s onboard diagnostics detects a fault in the engine management or emissions control system. That’s why the statement that best fits the material is that the MIL signals an emission-control fault. It isn’t primarily indicating a battery issue, a low fuel level, or low oil pressure, which are shown by other, separate indicators. If the MIL is on steadily, you can usually drive to a repair facility or end of shift, but if it’s flashing, stop driving and address it immediately to protect the engine and catalytic converter.
