Difference between Zirconia & Titania<br />
Zirconia<br />
Zirconia sensors have an 18mm thread size.<br />
Zirconia sensors generate a voltage,<br />
this voltage will be low if the air / fuel mixture is lean (high Oxygen).<br />
If the mixture is rich (low Oxygen) the voltage will be higher.<br />
The range is between 0 and 1 Volt.<br />
Titania<br />
Titania sensors have a 12mm or 18mm thread size.<br />
Titania sensors have a voltage supplied from the ECU (electronic control unit)<br />
and the sensor varies its resistance in relation to how much oxygen is in the exhaust.<br />
To identify this type of sensor, one of the wires is generally Red and the sensors look smaller.<br />
