What are the sensors on a Lexus GS300?

One of these sensors is an oxygen sensor, which on a Lexus GS300 is placed along the exhaust. If one of the oxygen sensors is reading incorrectly, then the computer won’t know how much fuel or spark to give the engine, and the result will be choppy idle and loss of power.

Where are the sensors located in a car?

The engines in cars today use a computer to diagnose information from sensors placed throughout the vehicle to control the air, fuel and spark to make the engine run properly. One of these sensors is an oxygen sensor, which on a Lexus GS300 is placed along the exhaust.

How do you replace an exhaust oxygen sensor?

Remove the oxygen sensor and discard it. Place the replacement oxygen sensor in the bung on the exhaust and tighten it in place using the oxygen sensor socket and the ratchet. Reconnect the wiring harness to the pigtail on the sensor. Repeat the process for any additional sensors on the exhaust.

Where are the oxygen sensors on a Lexus?

The Lexus will have a bank 1 and a bank 2 O2 sensor: one is near the firewall and in front of the catalytic converter; the other is behind the converter closer to the rear. They should primarily be the same part, just different lengths of wiring. The bulb part is connected to the exhaust. Figure 1. Location of the oxygen sensors.

When do you Know Your oxygen sensor is bad?

The first indication of a problem with your vehicle’s oxygen sensor is often when the “check engine” light comes on. Failing sensors cause jerky movements, trouble starting, and reduced fuel efficiency if they aren’t replaced. Oxygen sensors are necessary for vehicles to combine the proper ratio of gas and oxygen into fuel.

Where is the bank 2 O2 sensor on a Lexus?

Overall it’s an easy job, but care should be exercised in handling these parts.

They should primarily be the same part, just different lengths of wiring.

How do you replace an oxygen sensor on a Lexus?

Special oxygen sensor socket. If you have a thread chaser tool, it is a good idea to use it to clean out the bunghole after the sensor has been removed. It will make inserting the new sensor into the bunghole much easier. This will also help keep the sensor bulb from cross-threading.

Are there any genuine oxygen sensors for Lexus?

We offer a full selection of genuine Lexus Oxygen Sensors, engineered specifically to restore factory performance. Please narrow the Oxygen O2 Sensor results by selecting the vehicle.

Where do you place an oxygen sensor on a ratchet?

Place the oxygen sensor socket onto the end of a 3/8-inch ratchet and place it over the oxygen sensor. There is a slot on the oxygen sensor socket that will allow the wire lead from the oxygen sensor to run out the side and not get damaged.
