Abstract: An electronic throttle control system is described having a housing (22) with a motor (40), throttle valve (60), gear mechanism (48,102,104), and fail-safe mechanism (104,132,134). A spring member (132) attached to a gear member (104) and default lever (134), and which is biased when the throttle valve (60) is in its fully open and closed positions, operates to open the throttle valve in the event of an electric failure, thus allowing the vehicle to limp home. The spring member (132), default lever (134) and associated gear member (104) are interfit together as a group and inserted in the housing (22) as a subassembly (140), thus improving assembly time and expense.
