Land Rover Part Number: LR078546 - Throttle Body and Motor
LR078546 is a throttle body and motor assembly fitted within the engine intake system of 3.0 V6 D Gen2 diesel engines. The electric motor positions the throttle plate under control of the engine management system to meter intake air across idle, part-throttle and full-throttle conditions. The component mounts to the throttle housing and interfaces with the intake tract and associated sensors to deliver accurate airflow control; regular inspection of the throttle housing and electrical connections helps maintain consistent throttle response and avoid erratic idle or reduced performance related to airflow-control faults.
