Re: 2000 Alero 3.4 Heat Circuit Sensor 1 Bank 1
Hi- I have a 2000 Alero 3.4 with the same problem.

P0131 O2 sensor circuit low volts (bank 1 sensor 1).

Any chance you have the part number or anything for the AC Delco O2 sensor? Was it before or after the cat converter? I really appreciate the help.

Thanks again-

Nick
