Honda cb 190 Program Control Fuel Injection Failure

Failure causes of Honda cb 190 program-controlled fuel injection

The faults of fuel system are mainly concentrated in machinery and wiring. Because the fault is hidden and the symptoms are not obvious, technicians often misjudge it. This paper analyzes the fault diagnosis idea of Honda fuel system from several typical cases, that is, it is particularly important to read the data stream and analyze it effectively, especially to pay attention to whether the adjustment signal of ST, the opening of IAC, the rotation speed corresponding to MAP data match, and whether all signals are interrelated in the fuel closed-loop control process. At this time, we can observe whether the external conditions match the data performance.
