λ Oxygen Sensors

The exhaust gas oxygen sensor or Lambda sensor is the key sensor in the engine fuel control feedback loop. The on board computer uses the sensor’s input to balance the fuel mixture, leaning the mixture when the sensor reads rich and enriching the mixture when the sensor reads lean. When hot (at least 350 °C), the zirconium dioxide element in the sensor’s tip produces a voltage that varies according to the amount of oxygen in the exhaust compared to the ambient oxygen level in the outside air. The greater the difference, the higher the sensor’s output voltage. Sensor output ranges from 0.2 volts (lean) to 0.8 volts.

 

All our Lambda sensors have four wires: two for the heater, and two for the signal.
