Cylinders 1,3, and 5, the sensor after the catalytic converter. Find the exhaust pipe coming from the front of the vehicle and follow it until you see the O2 sensor after the catalytic converter.
On the Lexus SC 300, the oxygen sensors are typically located in the exhaust system. There are usually two types: the upstream (pre-catalytic converter) O2 sensor, which is found before the catalytic converter, and the downstream (post-catalytic converter) O2 sensor, located after it. Depending on the specific model year, these sensors can be found on both sides of the exhaust system, near the engine and the catalytic converter.

A/F Sensor for Bank 2 Sensor 1. It is the O2 sensor on the front manifold.
where is the O2 sensor on a 2002 chevy trailblazer
It is a real pain. My suggestion is to take it to a shop.
On a Lexus IS300, the O2 sensor signal can typically be found in the engine bay, connected to the exhaust system. The upstream O2 sensor is located in the exhaust manifold or just after it, while the downstream sensor is located after the catalytic converter. You can access the wiring harness connector for the O2 sensors by following the exhaust pipes and locating the sensors. For precise identification, consulting the vehicle's service manual is recommended.
The 2002 Chevy Cavalier 02 sensor can be found attached to the air cleaner housing. The O2 sensor will be on the back side of the air cleaner housing.

To replace the oxygen sensor (sensor 1, bank 1) on a Lexus SC 300, first, ensure the engine is cool and disconnect the negative battery terminal. Locate the sensor, typically found on the exhaust manifold or upstream of the catalytic converter, and unplug the electrical connector. Use an O2 sensor socket or wrench to carefully unscrew the old sensor, then install the new sensor by threading it in and tightening it securely. Finally, reconnect the electrical connector and the battery terminal before starting the vehicle to check for proper operation.
