In this article, we'll talk about such a useful thing as Programmed Fuel Injection or FI. All owners of the Honda CBR 600 F4i will sooner or later have to deal with such a problem as the flashing of the FI (MIL) light.
These short and longer blinks represent the error codes. Each blink carries a certain number, which in turn will tell you about your malfunction. Long blinks (1.3 seconds) - number 10, short (0.5 seconds) - number 1.
For example: the light flashes twice 1.3 times and once faster (0.5 seconds). This tells us that error code 21 is a faulty O2 sensor (California only). If twice fast (0.5 seconds) - code 2, the vacuum hose of the MAP sensor is removed or disconnected, the MAP sensor is not working.
