I'm sorry, but this vehicle isn't offered in the US, so I don't have specifics on it. The 1.4L isn't available here. However, If I recall correctly, I read the intake manifold needs removed to access it. I tried to find pics online. I found one. Take a look at it. If I am correct, that is under the intake manifold and there is a coolant line blocking it as well. There should be a rubber or plastic cover over the opening. The sensor is down inside.
Here is a link that explains how in general one is replaced, but yours is a bit different because of location:
Let me know if this helps. Sorry I don't have more info.
