Although I have covered the Bank 2 sensor install, I thought it still might be useful to cover Bank 1.

I discuss the symptoms to look out for if you think yours might be at fault too. For me it was issues with hot starts, and the reoccurring P0340 error code.

If I was to do it again I would probably remove the plenum to gain more access, but did managed to do it this time without any major dismantling.
