About the Nissan Pathfinder-Armada Engine Computer (ECU/ECM/PCM)

The Engine Computer (ECU/ECM/PCM) is your vehicle's brain, controlling fuel injection, ignition timing, emissions, and overall engine performance. A failing ECU can cause check engine lights, poor fuel economy, starting issues, and erratic engine behavior. The Engine Computer (also known as ECU, ECM, PCM) is a critical component for your Nissan Pathfinder-Armada.
