The Oxygen sensor is reads exhaust Gauze temperature.
A "thin" (fuel poor) air/fuel mixture burns hotter than a rich (fuel excess) mixtures. The O2 sensor monitors the heat of the exhaust to send the computer real-time information on the engine's fuel ratio. The O2 sensor closes the computer's information loop, allowing it to double check its calculations and adjust for unknown variables like air density and oxygen content.
Function
One shot the beginning Oxygen sensor monitors the engine. The moment continuously checks the converter to build definite its working.
Mixture and Heat
O2 (Oxygen) sensors are temperature probes that sit in the engine's exhaust stream and recorder it. The pc uses the monitored confidence to charge assorted parameters including injector pulse timing and ignition timing.
Location
Any automobile mythical thanks to 1996 Testament posses at least two Oxygen sensors, one between the engine and the catalytic converter and another after the converter.There are several different types of O2 sensors, but most (Lambda probes) contain a small piece of zirconium dioxide (or zirconia) crystal. Zirconium dioxide is an electroceramic material, which means it can convert heat energy into electrical energy. The computer reads the voltage emitted by the zirconia crystal and uses that to extrapolate for exhaust temperature, which is further extrapolated to indicate its oxygen content.
