I'm certain about B1S1. I looked under the hood this AM. You are correct --- it is clearly visible and reachable w/o removing the engine plastic cover. However, to remove the O2 sensor wire plug/harness, it appears to be further towards the rear of the engine. I could not see where the wires ended. So, looks like I need to remove the engine cover.
You do. Sorry.
