Evening all. I have an engine management light on, 1.25cc petrol 2006 Fiesta, Code P0030 Oxygen Sensor malfunction. My code reader does delete the code, but it comes back. Any quick fixes for this type of fault please?

    Thanks all; yes, as a heads up to anyone else doing this (the sensor behind the engine under the rear of the airbox), you WILL need a 22mm 'special' socket. I tried a ring spanner but just would not work. Saying that, the sockets are easily available online, £6 I paid, it was fine.
