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. 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.
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 are Bank 1 and 2 O2 sensors located?
Summary. If your DTC code says: Bank 1 Sensor 1 = O2 sensor located before the catalytic converter, on the side with Cylinder #1. Bank 1 Sensor 2 = O2 sensor located after the catalytic converter, on the side with Cylinder #1. Bank 2 Sensor 1 = O2 sensor located before the catalytic converter, on the side with Cylinder #2.
Where are the O2 sensors located on a diesel engine?
Generally, if we are talking about O2 sensors: Some Diesel engines have a lot of exhaust temperature sensors and it can use Sensor 1 – 2 – 3 – 4 etc. In these cases = Sensor 1 is located nearest the engine and the last sensor in the read of the exhaust system.

How much does it cost to connect an O2 sensor?
The O2 sensor is connected to a quick-disconnect wiring harness and the special socket is needed to prevent the wires from getting twisted and bound up using a normal socket. The special tool can cost from $8 – $100 depending on the style and brand you choose. Overall it’s an easy job, but care should be exercised in handling these parts.
How do you remove an oxygen sensor socket?
Spray the threads with lubricant to make removal easier. After the lubricant has had time to penetrate the sensor bulb threads, put the special socket over the threads and break it free. Once you have loosened the bulb, finish removal by hand. Figure 3. Special oxygen sensor socket.
What are test only SMOG stations ( O2 sensor )?
Ask-A-Tech! What are Test Only Smog Stations? The Oxygen Sensor, also known as the O2 Sensor is the component responsible for delivering exhaust information to a vehicle’s emissions computer. Most late model vehicles will be equipped with both a pre-CAT oxygen sensor and a post-CAT oxygen sensor.
Why do you need an oxygen sensor in a Lexus?
The oxygen sensors in your Lexus play a very important role in how your car operates. This little gadget can cause many headaches when it decides that it doesn’t want to function properly any longer.
Where is the O2 sensor located on a car?
Location: Oxygen sensors are always located along the exhaust path and before the tailpipe. In vehicles with only a pre-CAT O2 sensor the sensor will be located either directly before the catalytic converter or on the exhaust manifold.

Can a faulty oxygen sensor cause a smog failure?
Needless to say oxygen sensors require periodic replacement. Failure to do so will more then likely cause a smog check failure. 4 out of 10 high CO failed smog checks will be due to a defective, damaged or lazy oxygen sensor.
Location: Oxygen sensors are always located along the exhaust path and before the tailpipe. In vehicles with only a pre-CAT O2 sensor the sensor will be located either directly before the catalytic converter or on the exhaust manifold.
What does it mean when your O2 sensor is not responding?
If your upstream O2 sensor continuously gives out a voltage that is consistently about 450 mV, this may mean that your oxygen sensor is not responding to the fuel mixture. On the other hand, if the O2 sensor gives out a voltage that is constantly above 550 mV, that means that there is too much fuel mixture or your O2 sensor might be contaminated.
