It's the one after the cat. converter
There are 2 sensors The upstream O2 sensor is mounted in the ehxaust manifold The downstream O2 sensor is mounted in the exhaust pipe after the catalytic converter
The upstream heated oxygen sensor is located ahead of the catalytic converter The downstream heated oxygen sensor is located behind the converter

The upstream O2 sensor is mounted in the ehxaust manifold The downstream O2 sensor is mounted in the exhaust pipe after the catalytic converter
The upstream oxygen sensor is located in the exhaust pipe between the exhaust manifold and the catalytic converter The downstream oxygen sensor is located at the catalytic converter outlet
The speed sensor for a 1999 Chevrolet Cavalier is located on the side of the transmission. It has two wires coming out of it.
You have two.Sensor one is located in the exhaust manifold.Sensor two is located in the exhaust pipe downstream of the catalytic convert.Check related links below for removal of sensor one.
On a 1999 Toyota Corolla, the oxygen sensor is typically located in the exhaust system. There are usually two sensors: one upstream (pre-catalytic converter) and one downstream (post-catalytic converter). The upstream sensor is found on the exhaust manifold or near the front of the catalytic converter, while the downstream sensor is located further along the exhaust pipe after the catalytic converter. You may need to lift the vehicle or access it from underneath for better visibility.
It is in the exhaust after the converter.
