Bank 1 Sensor 2 Location on a Lexus IS250
The Bank 1 Sensor 2 on a Lexus IS250 is located on the driver’s side after the catalytic converter. It can be found downstream (post-cat) left, and it is situated on the driver’s side before the catalytic converter . This sensor is responsible for regulating and reporting on the temperature of the burn in the exhaust system, and it is essential for the proper functioning of the vehicle.
If you’re receiving a diagnostic trouble code (DTC) through an OBD-II scan tool related to the Bank 1 Sensor 2, it’s important to address this issue promptly to prevent potential damage to the catalytic converter.

What is oxygen sensor Bank 1 sensor 2?
“Bank 1” refers to the side of the engine where cylinder number 1 is located. In most vehicles, this is the side where the cylinder 1 spark plug resides. In V-shaped or boxer engines, Bank 1 is usually on the left side. “Sensor 2” indicates the downstream oxygen sensor after the catalytic converter.
Which sensor is Bank 1 sensor 2?
Usually O2 sensors are refered to as Bank 1 and Bank 2. Bank 1 would be the front sensor before the cat and Bank 2 would be the sensor after the cat. O2 sensors can all look alike but have different numbers because the flute design or voltage readings can vary. Be sure to use the correct sensor for your car.
Where is Bank 1 sensor 2 located?
The first sensor is placed between the engine and the catalytic converter. While the second is located behind it if you know this it’s very easy to locate the faulty O2 sensor.
Which O2 sensor is Bank 1 sensor 2 upstream or downstream?
Sensor 1 is the upstream oxygen sensor. It is the sensor that measures the oxygen content in the exhaust, providing an input to the computer, which determines how to adjust the air/fuel ratio. Sensor 1 is the sensor closest to the engine. Sensor 2 is the downstream oxygen sensor.
How much does it cost to replace the O2 sensor on a Lexus IS250?
Labor costs are estimated between $139 and $175 while parts are typically priced around $225.
Which is Bank 1 sensor 2?
Sensor 2 on the Bank 1 side means that it is located on the side of the engine that contains the #1 cylinder. The sensor 1 is tasked with reading the amount of oxygen in the exhaust system and then emitting a voltage measurement between 0.1 and 0.9 volts.
What side of the engine is Bank 1 sensor 2?
Bank. 1 is always located on the side of the engine with cylinder number 1 cylinder number 1 is always located at the front or the most forward cylinder on the engine. Bank.
How many 02 sensors are on a Lexus IS250?
Essentially, on the is250, there are four to be considered. There are 2 Upstream sensors (Bank 1 Sensor 1 and Bank 2 Sensor 1) and 2 Downstream sensors located after the cats (Bank 1 Sensor 2 and Bank 2 Sensor 2).
Is Bank 1 sensor 2 upstream?
The first oxygen sensor is known as upstream oxygen sensor and the second oxygen sensor is known as downstream oxygen sensor.
Where is the oxygen sensor bank 2 sensor 1 on a Lexus IS250?
In the Lexus IS250, Bank 2 Sensor 1 indicates the air fuel oxygen sensor, which You can find on the driver’s side of the vehicle. If You get under the vehicle and remove the plastic cover, You should see it relatively visible on the exhauSTSystem.
