Abstract:
The present teaching aims to provide: a cam angle sensor fault diagnosis apparatus for straddled vehicle, capable of detecting a fault of a cam angle sensor installed in a straddled vehicle and guessing a fault place; an engine system; and a straddled vehicle. A cam angle sensor fault diagnosis apparatus for straddled vehicle includes: a cam signal receiving unit connected to a signal output line through which a cam angle sensor outputs a cam signal in accordance with the rotation angle, the cam signal receiving unit being configured to receive a cam signal via the signal output line; a state determination unit that determines one or two fault states of the cam angle sensor from a disconnection state, a power supply fault state, and a ground fault state, distinguishably from the other fault states, in accordance with a signal level of a cam signal received by the cam signal receiving unit; and a signal output unit that outputs a fault signal representing the one or two fault states determined by the state determination unit, in such a manner that the fault signal representing the one or two fault states is different from a fault signal representing the other fault states.

Claim (Index 4):
The cam angle sensor fault diagnosis apparatus for the straddled vehicle according to  claim 3 , wherein\n in a case either where the holding period in which the signal level representing the main detection object is held is at least longer than the main reference period, or where the holding period in which the signal level representing the sub detection object is held is at least longer than the sub reference period, the state determination unit determines the one or two fault states of the cam angle sensor from the disconnection state, the power supply fault state, and the ground fault state, distinguishably from the other fault states, and in a case where the signal level of the cam signal has changed twice or more in a period that is at least shorter than the main reference period, the state determination unit determines the one or two fault states of the cam angle sensor from the disconnection state, the power supply fault state, and the ground fault state, distinguishably from the other fault states.
