The ECU can be seen in the center of the engine bay under the front engine cover. First we will need to remove the engine cover.

Lift back on each corner of the rear section of the engine cover. You will notice it will “pop” up easily with little effort.

Note that on the front portion of the engine cover, you will see two clips that will need to be disconnected from the air duct.
