O2 OXYGEN SENSOR

Engine Performance problem
1997 Toyota Corolla 4 cyl Front Wheel Drive Automatic 382000 miles

How many O2 oxygen sensors are on my Toyota Corolla engine. 1997 4 cylinder. When I look up the code P0136, it refers to the second sensor on bank 1 and where should I be looking for it.

Hi LouP,

It is the sensor after the catalytic converter.
