Upstream vs Downstream O2 Sensor – A Comparison – VehicleJack

The location of an O2 sensor is relative to the catalytic converter. An upstream sensor is closer to the head, whereas a downstream one is present at the back of the catalytic converter (CAT). In other words, an upstream is before the CAT and is also known as pre-CAT, whereas the downstream is after the CAT; therefore, it is known as post-CAT.
