You will find all O2 sensors threaded into the exhaust system at various points.
I find that situation occurs with our RX300 when someone hits/bumps the turn signal switch arm. Often the "toggle" for the lights changes to the "off" position. It's somewhat frustrating when you turn the car on at night expecting the headlights to turn on automatically. All you need to do is turn it back to the "on" position.
O2 sensors are always located on the exhaust system.O2 sensors are always located on the exhaust system.
Synthetic 0W30 if you can find it. If not use Synthetic 5W30

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 best place to find a Lexus SC430 would be at a dealership that sells the Lexus. One could also find a used Lexus at used car dealerships or online.
