I am only guessing, that that would be a heating element built into a 3 wire O2 sensor, and doesn't apply to a 2 wire sensor. As far as you still having the code after changing the sensor: 1) DID YOU ERASE THE ERROR CODE FROM THE ECM AFTER CHANGING THE SENSOR AND BEFORE TURNING THE KEY ON? 2) Are you aware the these vehicles usually have 2 O2 Sensors on them? Maybe you changed the wrong one, or maybe they were both bad. Hope this helps.
