Accord L4-2156cc 2.2L SOHC (1991)
Malfunction Indicator Lamp: Description and Operation
The ECU illuminates the "CHECK ENGINE" warning light, located on the instrument panel left side, above the gauges, if a problem is detected in any
of the monitored systems. This light is the primary means of notifying the driver that a problem exists. The ECU also stores a trouble code in erasable
memory, and flashes the LED on the ECU at the same time.
