The term MOST-Likely used to describe the speed of O₂ sensor oscillations between rich and lean is: A) trip B) drive cycle C) switch ratio D) heat soak

Question

Quizplus · Accepted Answer

The term "switch ratio" is most likely used to describe the speed of sensor oscillations between rich and lean conditions in an oxygen sensor. This term refers to how quickly the sensor can switch its output signal from indicating a rich mixture to a lean mixture and vice versa, which is crucial for the engine control unit (ECU) to adjust the fuel mixture for optimal performance and emissions control.
