What steps should I take to replace the oxygen sensor in my 2015 Ford Fiesta 1.5 TDCi MK7? Also, where is the sensor located? Can you help me?

    Hi,

    The sensor is located right at the top of the cat in front of the engine. It simply screws out, and the new one screws back in again. Do it when the engine is warm and be sure to use a good fitting tool so that it doesn't slip and round the nut.

    @TomsFocus Are there no two oxygen sensors? That's not the blue cable in the photo, is it? And what are those two sensors, the green and blue ones?

    Those two are temperature sensors. The oxygen sensor is higher up. It's not shown on your picture.
