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.

The sensor runs under the seat and out to the exhaust pipe under the back of the car. You will have to remove the two bolts holding the seat to replace it.

in the car
In a 2002 Lexus RX 300, Sensor 1 Bank 1 refers to the upstream oxygen sensor located on the driver's side of the vehicle, before the catalytic converter. To replace it, first, ensure the engine is cool and disconnect the negative battery terminal. Then, locate the sensor, unplug the electrical connector, and use an oxygen sensor socket or wrench to unscrew it from the exhaust pipe. Install the new sensor by reversing these steps, ensuring it's securely tightened and the connector is reattached.
I don't know the cost of the sensor but it is just a mamtter of unplugging the old one, unscrewing it and installing the new one. GoodluckJoe
