Ford BL3Z-9E926-B Throttle Body Assembly

The Ford BL3Z-9E926-B is an electronic throttle body assembly designed for the 3.5L GTDI EcoBoost V6 engine. It integrates the throttle position sensor and actuator motor into a single aluminum housing unit. This component regulates airflow into the engine intake manifold based on accelerator pedal position signals from the ECU. The assembly features a 6-pin electrical connector interface and is mounted on the left (driver) side of the intake manifold. It supersedes the original BL3Z-9E926-A design with updated internal motor logic and improved gear durability. The unit is calibrated for drive-by-wire systems requiring precise idle control and rapid throttle response under boost pressure.
