Whether it looks alright or not, is unfortunately no help to you. If they go they do not look any different.

You are probably best to change the sensor, get the EML code reset & see if that helps.

Even if it is not the cause you need to eliminate obvious faults to help with the rest of the diagnosis.

If you can, you are best to get the correct sensor, rather than one of the "universal" ones, as I have found them to be cheaper yes, but less reliable on the whole. Some cars are more sensitive in this respect than others.

It is possible, but it certainly won't help.

One of the symptoms in some cars is rough/erratic idling, so as you know it seems to be dodgy, change it & then see what happens.

What martycossie says could be worth a try too, also when you are under the bonnet, have a good look round for any loose plugs or hoses around the intake side of the engine.
