P1133 - Heated Oxygen Sensor (HO2S) insufficient switching Bank 1 sensor 1

If I remember right that's the oxygen sensor before the cat, driver side. I think there's a way to test them with a multimeter...if you've got over 100,000 though you might want to swap out anyway; I just replaced mine with Bosch.
