The A/F sensor is a planar dual-cell limit current sensor. The sensor element of the A/F sensor is the combination of a Nernst concentration cell (sensor cell) with an oxygen pump cell, which transports ions. It has a heating element in the element.
The sensor is capable of accurately measuring λ=1, but also in the lean and rich range. With its control electronics, the sensor emits a clear and continuous signal over a wide λ range (0.7 < λ < air).
The exhaust gas components diffuse through the diffusion gap at the oxygen pump electrode and the Nernst concentration cell, where they are brought to thermodynamic equilibrium.
An electronic circuit controls the pump current through the oxygen pump cell so that the composition of the exhaust gases in the diffusion gap remains constant at =1. Therefore, the A/F sensor is able to indicate the air/fuel ratio by this pumping current. Additionally, a heating element is built into the sensor to ensure the required operating temperature of 700 to 800°C (1,292 to 1,472°F).
