DESCRIPTION

The throttle body mounts to the intake manifold. The throttle position sensor and throttle actuating DC motor are integral to the throttle body. The throttle body is a non serviceable item, replace the throttle body as an assembly.

The throttle blade will not close completely when engine is shut down. This engine off blade position is for start up. The electric throttle body will adjust the throttle blade for idle control as the idle air control valve adjusted idle speed previously on cable actuated throttle bodies. The electric throttle body will also adjust the throttle blade for normal driving operation. The throttle blade will move to the engine off blade position if throttle body codes are set to provide air for limp-in mode.
