Malfunction Indicator Light (MIL) comes on and remains on for 3 seconds as a bulb test each time ignition switch is turned to ON position. If PCM receives an incorrect signal or receives no signal from battery voltage input, charging system, coolant temperature sensor, manifold absolute pressure sensor or throttle position sensor, MIL will glow. MIL will also glow if certain emission-related faults exist. This warns driver that PCM is in limp-in mode and immediate repairs are necessary. MIL can also be used to display fault messages. For additional information, see TESTS W/CODES - 3.3L GASOLINE article in the ENGINE PERFORMANCE section.
