Oxygen Sensors – Technology, Types, Evolution, and Life Expectancy

Since the implementation of OBDII, the oxygen sensor has been a main staple of engine management systems. Modern oxygen sensors are much faster and more accurate than their older counterparts. This allows the engine to enter closed loop control faster which decreases emissions and fuel usage by as much as 15-20%.  O2 sensors are separated
