Quick Check List
1. Count the number of wires on the original sensor.
2. Check the colour of the wires
a. If the sensor has black, grey, purple or white wires, it will be a Zirconia sensor.
b. If the sensor has one red wire (and or yellow) with the possible exception of some
Japanese vehicles, it will be a Titania sensor.
3. If it is a Titania sensor then check the original thread size of the sensor.
4. If you have ant doubt or query, please contact us.
* In some applications fitted with three wire Titania oxygen sensors, the output is 0 to 5 volts. |
