Lambda sensors operate by measuring the amount of oxygen in the exhaust
The levels calculated by the lambda are sent as data to the ECU which then calculates and determines how best to achieve the ideal mixture of air and fuel at combustion
Whilst the pre-cat lambda sensor communicates to the ECU regulating the air/fuel ratio;
the post-cat lambda sensor performs a diagnostic role, monitoring the catalytic converter
Before a vehicle fails an emission test or the engine check light appears, drivers may notice increased fuel consumption and/or a rough idle
Many lambda sensor failures will simply be a result of age
The lambda sensor operates in extremely high temperatures so damage to the heater element of the sensor is the most frequent fault, along with vibration/damage and contamination
