About the Toyota Avalon Engine Computer
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.
Replacement Guide
ECU replacement requires matching the unit to your vehicle's VIN. Some units are plug-and-play while others need dealer programming. Used OEM units from the same model year and engine are often preferred as they may not require reprogramming.
