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
Oxygen Sensor Questions Answered
If an O2 sensor is not reading properly or is borderline, it should be replaced regardless of its age or mileage.
Why O2 Sensors Fail To Calculate Exhaust Levels Over Time
As miles accumulate, O2 sensors effectively “catch a cold,” meaning they can’t breathe like they should.
