Where is the ECM on a 2002 Pontiac Grand Am?

The Engine Control Module (ECM) on a 2002 Pontiac Grand Am is typically located under the hood, near the firewall, often attached to the inner fender well. It's usually a fairly large, rectangular black box with numerous connectors. However, its exact location might vary slightly depending on the engine and options installed on the specific vehicle.

To be certain, you should:

* Consult your owner's manual: This is the best resource for the precise location.

* Check online repair manuals: Sites like Chilton or Haynes often have diagrams showing the ECM's location.

* Look for a large black box with many wires near the firewall: This is the most likely candidate.

Remember to disconnect the negative battery terminal before working near any electrical components.
