Where is the engine control module located on a 2001 Chevy silverado?

The Engine Control Module (ECM) on a 2001 Chevy Silverado is typically located under the hood, on the driver's side, often attached to the inner fender well. However, the exact position can vary slightly depending on the engine size and other options.

To be certain, you should:

* Consult your owner's manual: This is the best resource for the exact location in your specific vehicle.

* Look for a large, rectangular black box with numerous connectors: This is the most likely candidate. It may have labels or markings indicating it's the ECM or PCM (Powertrain Control Module, which often functions as the ECM).

* Use a wiring diagram: A wiring diagram for your specific year and model will clearly show the ECM's location.

Don't be afraid to look around thoroughly. It might be partially obscured by other components.
