Idle Position Switch

This switch is a vacuum controlled switch mounted on a bracket on right side of engine compartment. This switch senses intake manifold vacuum and sends an electrical signal to ECM in relation to amount of manifold vacuum. The ECM uses this information to distinguish between closed throttle (idle) and open throttle positions.
