P1133 HO2S Insufficient Switching Sensor1
The PCM monitors o2 Sensor activity for 100 seconds, and counts the number of times o2 signal voltage crosses from rich to lean, and lean to rich thresholds. If the PCM doesn't see the o2 sensor switch enough times, P1133 will be set.
Lean to Rich: Less than 300 mV to more than 600 mV
Rich to Lean: More than 600 mV to less than 300 mV

I asked in the other thread, but I don't know if it was answered, how did you extend the harness from the o2 sensor?

It looks like a ZZP plug-and-play extension harness.
That o2 sensor is brand new out of the box from ZZP. There is no way it's bad.

New doesn't mean it's good. Even AC Delco has their bad days, like any other company.
