    lambda or oxygen sensors are used to reduce vehicle emissions by ensuring that engines burn their fuel efficiently and cleanly, by measuring the proportion of oxygen in the remaining exhaust gas, and by knowing the volume and temperature of the air entering the cylinders amongst other things, an ECU can determine the amount of fuel required to burn to ensure complete combustion.

    not sure what engine you have most sensors are approx 80

    Increased fuel consumption, Hesitation on acceleration, Stalling, Rough idling could all be caused by the sensor.

    what was the fault code? if it was exhaust gas exit temp then yes looks like the above part.
    if the fault code was lambda/oxygen sensor then you need the part below.
