The Honda Accord 2010 year (Tao/Thailand, 8th generation) 2.0 R20A engine uses an Engine Control Unit (ECU/engine computer) that manages:

• Fuel injection timing & amount (electronic multi-point injection system).
• Ignition timing (coil-on-plug ignition).
• Variable valve timing (i-VTEC system) control.
• Electronic throttle body (drive-by-wire system).
• Idle air control & emissions monitoring (EGR, O2 sensors, catalytic converter).
• OBD-II diagnostic functions for fault detection and communication with scan tools.

The ECU for this model is often marked with a code like ''Y9'' on the sticker/label.

• ''Y9'' indicates the specific ECU version used for the Accord 2.0 R20A engine (market-specific).
• It is mounted in the engine bay fuse/ECU box area or near the passenger footwell, depending on version.
• It communicates with other modules (ABS, transmission, immobilizer, etc.) via CAN bus.

Would you like me to also list the exact ECU part numbers (37820-XXXX-Y9) that match this Accord 2010 2.0 R20A, so you can cross-check with replacements?
