When I had that problem on my 1997 buick lesabre, I had to replace the catalyst converter and the 02 sensor on it. It resolved the issue with the code.
It has a conector, just un plug it. Then remove the 02 sensor from the exhaust.

Disconnect positive cable first then negative. Reconnect the negative cable first then positive.
Bank 1 sensor 1 was the upstream 02 sensor located before the catalytic con on my 03.
Check your battery cables. Some computerized vehicles have to be reset. Disconnect the battery for about 5 minutes and then reconnect.

First you need to find which one is bad. After you find out which one is bad you remove the 02 sensor from the exhaust pipe with an 02 sensor socket. Then you disconnect the sesor from the electrical connector. After that you can install the new one. Be carefull it's not the easist job to do in the drive way.

Hi Every one Can you help meWhere Is the heater 02 sensor and heater circut fault sensor 1 for 1999 Honda Civic?
That is the sensor in the catalytic converter.
That would be the sensor after the catalytic converter.
the black wires are for the heater circuit, the blue and white are the sensor wires. the universal sensor probably wont work though, its best to bite the bullet and get the correct one from toyota.
