Where is the intake manifold runner control sensor on 2001 3.8 ford mustang?

The 2001 Ford Mustang 3.8L V6 doesn't have a dedicated "intake manifold runner control sensor" in the same way some other engines with variable intake geometry do. Instead, the system uses a different approach. The intake manifold runner control is managed by a Variable Intake Manifold (VIM) system, and the position of the runners is controlled by a motor, not a sensor that specifically reports its position.

There's no single sensor that directly reports runner position. The engine control module (ECM) monitors engine conditions (like engine speed and load) and controls the motor which changes the runner position accordingly. Any fault diagnosis related to the VIM system would focus on the motor itself, its wiring, or the ECM's control of the system. You'd likely find diagnostic trouble codes (DTCs) related to the VIM if there's a problem.
