Where is the sensor?

I have a 1998 Toyota Avalon with a 3.0 v 6 engine. The check engine light is on with a code of P0135. That indicates a bad O2 sensor in Bank one-sensor one. I can not find this sensor. I have found the bank one sensor 2 coming out of the manifold and sensor 3 after the Catalaytic Converter, but, for the life of me, I can not find the bank one-sensor one.

Can anyone help?

it should be right on manifold or on pipe before cat Opposite of bank 2
bank 1 is the bank that contains cylinder 1
most likely the right side i believe

It's the one between the rear of the engine and the firewall on the exhaust manifold. Can be gotten to from the top reaching behind from the drivers side.
