The ECU (Engine Control Unit) on a 2001 Ford Taurus is typically located
under the dashboard, on the driver's side. However, it's not always easily accessible and might be tucked away behind other components. You'll likely need to remove some trim panels to reach it.
It's strongly recommended to consult a repair manual specific to your 2001 Ford Taurus. This manual will provide diagrams and instructions for accessing the ECU safely without causing damage. Improper removal can damage wiring harnesses or other components.
