Number of Oxygen Sensors in a Lexus GS300
The Lexus GS300 typically has four oxygen sensors. These sensors are positioned in the exhaust pipe and are responsible for measuring the amount of oxygen in the exhaust. They play a crucial role in maintaining the proper fuel-to-air ratio for optimal engine performance and emissions control.

How many O2 sensors does a Lexus is300 have?
There are 4 sensors on this car, the front 2 are air fuel ratio sensors, the 2 rear are oxygen sensors. The one you refer to is VERY VERY common to fail, it’s under the car in the center exhaust pipe, the wire runs up into the cabin and it plugs in under the passenger front seat (not at all fun or easy to change).
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.
How many O2 sensors does a 2002 Lexus es300 have?
There are FOUR (2 A/F Sensors, and 2 Heated Oxygen Sensors) on this vehicle.
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.
How can I tell which O2 sensor is bad?
A decrease in fuel efficiency can be a telltale sign that an O2 sensor is not performing as it should. This can happen because of a fuel mixture that is either too lean or too rich. Such a swing in A/F ratio is a sign that an upstream or control sensor is faulty.
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.
How many O2 sensors does a Lexus es300 have?
The Lexus ES has four oxygen sensors.
Should I replace all 4 O2 sensors at once?
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.
How many O2 sensors does a V6 have?
Modern vehicles with V-6 or V-8 engines could have as many as four O2 sensors — one located in each cylinder bank and one after each catalytic converter. If either the oxygen sensor in the cylinder block or the one for the catalytic converter fails, your vehicle could experience serious engine problems.
How many O2 sensors do you 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.
