Toyota Oxygen Sensor

How Do Oxygen Sensors Work?

Oxygen sensors operate based on a chemical reaction that generates a voltage signal proportional to the level of oxygen in the exhaust gases. Here’s a simplified breakdown of their operation:

  1. Sensing Element: The core component of an oxygen sensor is typically made of zirconia ceramic coated with a layer of platinum.
  2. Chemical Reaction: As exhaust gases pass over the sensor, a chemical reaction occurs between the platinum and the oxygen in the exhaust.
  3. Voltage Generation: This reaction generates a voltage signal that is sent to the engine control unit (ECU). The voltage varies depending on the oxygen concentration in the exhaust gases.
  4. Data Interpretation: The ECU interprets this signal to determine whether the engine is running rich (too much fuel) or lean (too much air) and adjusts the air-fuel mixture accordingly.
