Where is the idle air control valve located on a 2001 Chevrolet Impala?

On a 2001 Chevrolet Impala, the Idle Air Control (IAC) valve is typically located on the throttle body. The throttle body itself is usually found on the intake manifold, near the engine's front. It's a relatively small, cylindrical valve often with a single electrical connector.

However, precise location can vary slightly depending on the engine type (3.4L V6 or 3.8L V6). The best way to locate it is to:

1. Consult your Impala's repair manual: This is the most reliable source for the exact location and appearance of your IAC valve.

2. Use an online parts diagram: Many websites (like auto parts store websites) allow you to input your vehicle's year, make, and model to access diagrams showing the location of all components. Search for "2001 Chevrolet Impala parts diagram" and look for the throttle body and IAC valve.

3. Visually inspect the throttle body: The IAC valve is usually easily visible once you locate the throttle body. Look for a small valve with a wire harness connected.

Be cautious when working near the throttle body and IAC valve. Disconnect the negative battery terminal before working on these components to prevent accidental damage or injury.
