Abstract
An electronic throttle control unit includes an air bypass channel having a removable obstruction that opens in response to receiving an electronic throttle control fault signal and thereby allowing the vehicle a limp home condition. The throttle plate defaults to a fully closed position upon engine-off to substantially prevent evaporation and escape of hydrocarbons from the intake manifold to the atmosphere.
