Bank 2, sensor 2 is at the bottom of the engine as you look in from the bumper. It is installed in the exhaust pipe just below the catalytic converter. The bank 1, sensor 2 is at the same location on the back of the engine below the firewall.

SOURCE: Where exactly are the Oxygen Sensors I think

If your car has 4 O2 sensors, there should be two located on the rear of the motor by the exhaust pipe where if enters the engine. And the other two are located after the catalitic converter on the tailpipe under the car. Bank one will always be on the side where spark plug for cylinder 1 is located. Hope this helps.

Where is sensor1 bank1 o2 sensor on a 95 avalon


Bank refers to the side of the engine. Bank1 is always the same side as the number one cylinder. Bank 2 is always the other side of the motor on a v-6 or v-8

Sensor refers to before or after the catalytic converter. Sensor 1 is always before the cat. sensor 2 is always after the cat.

Bank1 sensor 1 on your vehicle - since the number one cylinder is on the backside of the motor closest to the firewall the B1S1 - O2 would be in the exhaust manifold on the back side of the engine before the catalytic converter.
