The Lexus RX300 has multiple oxygen sensors located in different parts of the exhaust system. According to the search results, there are two sets of oxygen sensors on the Lexus RX300. One set is located just past the catalytic converters, while the other set is located on the exhaust manifolds before the catalytic converter. The oxygen sensor nearest to the radiator can be easily accessed with an oxygen sensor socket and a wrench.
It’s important to note that the number and location of oxygen sensors may vary depending on the specific model year and engine configuration of the Lexus RX300. It is always recommended to consult the vehicle’s owner’s manual or a trusted mechanic for the most accurate and up-to-date information.

How many oxygen sensors does a Lexus rx300 have?
Materials Needed. There are two sets of oxygen sensors on the Lexus RX.
Can I drive with a failing O2 sensor?
Can I Drive My Car With A Bad Oxygen Sensor? We recommend against driving with a bad O2 sensor as the powertrain is not running on the correct fuel mixture. While it may perform fine in the beginning, if your engine is running rich and using too much fuel it might begin to clog the catalytic converter.
Where are all the O2 sensors located?
Most cars have at least two oxygen sensors located throughout the exhaust system; at least one in front of the catalytic converter and one or more downstream from the catalytic converter. The “pre-cat sensor” regulates fuel supply, while the downstream sensor measures the efficiency of the catalytic converter.
Where is Bank 1 sensor 1 on a Lexus RX300?
This sensor works for Bank 1 Sensor 1 (before catalytic converter, access from underneath the vehicle) and Bank 2 Sensor 1 (between the engine and radiator, accessed from the top). Note: Recommend using two jack stands for added safety while working under the vehicle.
