Where is the bank 1 sensor 2 located?

updated 3/1/09
I just want to say thanks for you information on the O2 sensor location. I had heard conflicting stories. Some said that bank 1 was the bank that the number 1 cyl. Was located on. However there was only 1 sensor on that side at the manifold, then the exhaust pipe crossed over and hook up to the right bank. On the passanger side there three. 1 at the manifold, 1 before the cat, 1 after the cat. So if I understood you correctly then the sensor located at bank 1 one sensor 2 that would be the sensor on the passanger side(right bank) before the converter. Thanks for all your help.

Hello,

Bank 1 is on the passenger side

Bank 1 Sensor 1 would be in the exhaust manifold

Bank 1 Sensor 2 would be the next sensor back.

If you have a dual exhaust it would be the sensor just in front of the cat.

Single exhaust would also be in front of the cat the exact location would depend on the design of the exhaust going into the cat.

Bank 2 would be the drivers side and the sensors run the same as bank 1
