Engine control in the Camry Hybrid

The 2AR-FXE is a 2.5-liter gasoline engine used in Toyota’s hybrid powertrain. Its engine control module manages functions such as fuel injection, ignition timing and electronic throttle operation. It also works with the hybrid control system to deliver the engine output requested for driving and charging.

In practice, this coordination helps determine when and how the gasoline engine contributes alongside the electric motor. The hybrid system controls the broader interaction between the engine, motor and battery, while the engine controller governs the engine’s operating conditions.
