Disconnect the O2 sensor from the main engine harness. Using a multi-meter, measure the resistance between the two black wires (that are actually connected to the O2 sensor, not the engine harness side).
Is the reading between 15-40ohms? If no, replace the O2 sensor.
If you don't have a meter, then your guess is as good as anyone elses on here - so go with the shotgun approach to troubleshooting and just replace the thing.

Just what I needed to know !! However, I still have a doubt, is the "heater" part of the sensor or a different part ??
