Toyota 22030-37020 Throttle Body Assembly

The Toyota 22030-37020 is an electronic throttle body assembly designed for precise airflow regulation in 1.8L 4-cylinder engines. The unit integrates a throttle position sensor (TPS) and electric actuator motor for drive-by-wire control. It features a bore diameter calibrated for the 2ZR-FE engine platform, ensuring factory-spec idle stability and throttle response. Constructed with die-cast aluminum housing and composite throttle plate, the assembly undergoes flow testing to meet OEM airflow calibration standards. The electrical connector uses a sealed 6-pin interface compatible with the vehicle engine control module. Mounting flange pattern matches original equipment specifications for direct bolt-on installation without modification.
