Question

Quizplus · Accepted Answer

Closed loop fuel control is the term used to describe when the engine's computer (ECU or ECM) begins to control the fuel mixture based on feedback from sensors, including the oxygen sensor (O2 sensor), once the engine has reached its operating temperature. This allows for more precise fuel management compared to open loop control, which operates without feedback from the oxygen sensor.
