I had the code scanned on my 2003 corolla by autozone. It said I had a bad catalytic converter. My mechanic said it could be the sensor behind the cat. A new catalytic converter was 979 dollars. Bosch 15733 Oxygen Sensor, Universal Type Fitment

My mechanic wanted 235 dollars to do the sensor so I took a chance and did it my self. My check engine light was on for 5 months till I changed the sensor. I disconnected the battery to reset the light. I have driven 1100 miles since then with no light. Changing the sensor was a piece of cake.  Bosch 15733 Oxygen Sensor, Universal Type Fitment

The old sensor came out easily enough with a wrench. Installed the new one and connected the wires. Done in about 4o minutes. The sensor came with a chart to tell you what coor wire to connect to which. No problems.
