Everyone keeps saying the Bank 1 Sensor 1 is the one in the back of the engine by the firewall, but according to my Haynes Manual it shows it as the one in front near the radiator (Pg 6-18). Can someone please clarify as soon as possible since I have an Oxygen Sensor here ready for install and I was about to put it in the front Thanks Dave

Please excuse my ignorance, I'm a Home Theater guy and not a real car guy, but what exactly "is" a B1S1??? You say to replace it, but what is it??? Oxygen Sensor??? Thanks for any help Feel free to do this to me for such a stupid question :chairshot: Dave
