What is the malfunction indicator light (MIL)?
This is a warning light located on the vehicle’s dashboard. The color of an illuminated MIL can be red, amber, or yellow. If the MIL stays illuminated while the engine is running, the vehicle’s “OBD II” system has detected a potential emissions problem. The MIL can read, “Check Engine,” “Check Engine Soon,” or simply be an image of an engine. Certain severe engine malfunctions may cause the MIL to blink or flash on and off. These conditions require a reduction in speed and immediate service. Consult your owner’s manual for further guidance.
