An engine air shutoff valve system with an improved sensor that facilitates a position detection of the shutoff valve is disclosed. The air shutoff valve system may include a shutoff valve, an indicator, and at least one solid-state proximity sensor. The shutoff valve is moveable between an open and closed position. The indicator is operatively coupled to the shutoff valve. The indicator is movable between a normal state and a tripped state in respective correspondence with the open and closed positions of the shutoff valve. At least one solid-state proximity sensor can be configured to detect when the indicator is in the tripped state.
