Oxygen sensor collect the data via a ZrO2 ceramic chip which is centered in the sensor prob. It is covered by metal prob shell to protect direct damage from contaminate and heat of the exhaust gas. The air of exhaust gas in the react chamber and fresh air from atmosphere would have a O2 density difference which cause the ZrO2 and Exotic metal plating to create a voltage difference. The chip will send the electronic signal to ECU for further calculation into a digital data
