Lambda Sensor

In contact with exhaust gas, the oxygen sensor generates an electrical signal of which the value
represents the amount of oxygen present in the exhaust gas itself.
Because the censor and needs to reach a temperature of about 350°C to function correctly, in
order to avoid thermal shock at cold engine condition, the computer foresees in sensor heating.
Sensor and heater are integrated in a ceramic element thus obtaining fast heating. In this way
in very short period of time is obtained the control in so-called closed loop ( lambda control)
