Lexus IS300 O2 Sensors
The Lexus IS300 has a total of four oxygen (O2) sensors. These sensors are named B1S1, B1S2, B2S1, and B2S2. “Bank 1” refers to the first bank of cylinders (cylinders 1-3), and “Bank 2” refers to the second bank of cylinders (cylinders 4-6).

How many O2 sensors do I have?
Most cars will have several oxygen sensors. There will be one in front of the catalytic converter and one in every exhaust manifold. Modern vehicles usually have at least four oxygen sensors placed at key points in the exhaust system.
Do I have to replace all 4 O2 sensors?
Do I need to replace all of the sensors at once? It is best to replace O2 sensors in pairs. For example, if you replace the downstream left sensor, you should also replace the downstream right.
Can I replace my O2 sensor myself?
You can do these yourself if you can get to them you just need a good O2 sensor wrench and some seafoam green label deep creep creeping oil. They tend to get pretty stuck if they have been on a while. A little anti seize helps on install.
Is it OK to drive with a bad 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.
How many 02 sensors does a gs300 have?
There are (4) O2 sensors on that car, one in each exhaust manifold and one in back of each catalytic converter.
How much does it cost to replace the oxygen sensor on a Lexus IS300?
The average cost for a Lexus IS300 Oxygen Sensor Replacement is between $762 and $937. Labor costs are estimated between $506 and $638 while parts are priced between $256 and $299. This range does not include taxes and fees, and does not factor in your unique location.
Should I replace all O2 sensors at once?
Manufacturers recommend replacing O2 sensors in pairs (both Upstream or both Downstream). An older, slower sensor can cause an imbalance in the engine management system, leading to poor fuel economy and possible damage to the catalytic converter.
Are oxygen sensor 1 and 2 the same?
What is Sensor 1 & 2? The sensor number is telling us where on the exhaust system the O2 sensor or Exhaust temperature sensor is mounted. The 1st sensor is located closest to the engine and the last is located at the rear of the exhaust system.
Can I replace 1 O2 sensor?
Manufacturers recommend replacing O2 sensors in pairs (both Upstream or both Downstream). An older, slower sensor can cause an imbalance in the engine management system, leading to poor fuel economy and possible damage to the catalytic converter.
How much does it cost to replace 4 O2 sensors?
Many sensors, nonetheless, cost between $20 and $100. Your mechanic’s labor costs also likely vary based on a few factors, including how difficult it is to access your sensors. Typically, labor costs for a sensor replacement are around $150.
