P1133 is in the OE manual for '00OBW; it says DTC P1133 - FRONT OXYGEN (A/F) SENSOR HEATER CIRCUIT HIGH INPUT. (sorry about the caps-cut&paste).
As already mentioned there was a recall on the front o2 sensors where they'll replace it for free (some piece can break off or something I think); so if it hasn't been done yet and your vehicle was included might as well get it done.

I would expect so but I hate to troubleshoot and then find
there was a difference.

I had this same code P1133 and the OBDII said however (LOW) below and I was able to clear the code by replacing the sensor. Used a Denso 234-9018. Do not buy a UNIVERSAL O2 sensor. It will NOT work!! Needs to be OEM on this car. Believe me I tried it. The OE unit made by Denso can be bought at auto parts stores and is the same as the dealer OE part. 3x check that they sell you the right unit for a MT Legacy which is not the same at the AT one.
It seems the diagnostics pathway attached above is just for a high condition.
My Legacy had 115k, started to smell a little rich, and then on cold mornings, idle RPM would be very high for a few minutes and then when the car warmed was fine. Seems that both the sensor heater was messed up as well as the actual o2 sensor part.
The sensor came out easily despite the awkard angle.
I spend hours on mind so wanted to at least share my experiences.

Let the car idle a few minutes and hold the bung with an open end wrench, then turn sensor.
