Where is the bank 1 sensor 1 on a 2010 Lexus rx350?
As a seasoned auto repair professional, I often get questions about the location of specific sensors in vehicles. One common query is about the Bank 1 Sensor 1 on a 2010 Lexus RX350. This sensor plays a crucial role in monitoring the engine's performance and ensuring optimal fuel efficiency. In this article, I'll explain where to find it and why it's important.
Understanding Bank 1 Sensor 1
Before diving into its location, let’s clarify what "Bank 1 Sensor 1" means. In automotive terms:
- Bank 1: Refers to the side of the engine where cylinder 1 is located. On a V6 engine like the one in the 2010 Lexus RX350, this is typically the side closest to the firewall (the rear of the engine bay).
- Sensor 1: Indicates the oxygen sensor located upstream, before the catalytic converter. This sensor monitors the air-fuel mixture in the exhaust gases and sends data to the engine control unit (ECU) to adjust fuel delivery.
Location of Bank 1 Sensor 1 on a 2010 Lexus RX350
On the 2010 Lexus RX350, the Bank 1 Sensor 1 is located on the exhaust manifold of the engine's Bank 1 side. Specifically, it is positioned:
- On the rear side of the engine, closer to the firewall.
- Mounted directly on the exhaust manifold, before the catalytic converter.
- Accessible from the top of the engine bay, though it may require removing some components for better visibility and access.
Tips for Locating and Replacing the Sensor
If you’re planning to locate or replace the Bank 1 Sensor 1, here are some tips to make the process smoother:
- Use a repair manual: A detailed repair manual for the 2010 Lexus RX350 can provide diagrams and step-by-step instructions.
- Disconnect the battery: Always disconnect the battery before working on electrical components to avoid short circuits.
- Use the right tools: An oxygen sensor socket and a ratchet wrench are essential for removing and installing the sensor.
- Be cautious of heat: If the engine has been running, let it cool down before working near the exhaust manifold to avoid burns.
Why is Bank 1 Sensor 1 Important?
The Bank 1 Sensor 1 is critical for maintaining your vehicle's performance and efficiency. It ensures the engine runs with the correct air-fuel mixture, which helps:
- Improve fuel economy.
- Reduce harmful emissions.
- Prevent damage to the catalytic converter.
- Maintain smooth engine operation.

Frequently Asked Questions
What side of the vehicle is bank 1?
Identify Bank 1 — Determine which side of the engine is Bank 1. In a V-type engine, Bank 1 is the side with cylinder number one. For inline engines, there is only one bank, so locate the exhaust manifold connected to cylinder number one.
Where is bank 1 sensor 1 on a Lexus RX300?
Bank1 Sensor1 is mounted to the exhaust manifold on the side of the engine closest to the firewall.
Is bank 1 sensor 1 on driver side or passenger side?
The real truth is that you can't simplify it and say that bank 1 is on the driver's side or vice versa because different engines can have cylinder 1 on different sides. We drive on different sides also, so it's just really confusing and misleading to guess which side bank 1 -2 is.
How much does it cost to replace a bank 1 catalytic converter?
For direct-fit options, a replacement can cost anywhere from $300.00 to $2,500.00, depending on the model, for just the cost of the part. You should also think about labor costs, which could cost between $70 and $130 an hour to install the converter.
What is the location of bank 1 sensor 1?
If you are staying in front of your car and looking into the windshield, the bank one sensor one will be the sensor on the left( where the air filter box is) , before the catalytic converter ( upper sensor).
Where is the bank 2 sensor 1 on a 2010 Lexus rx350?
Bank 2 Sensor 1 will be close to the manifold accessible through the engine bay (Figure 3). Bank 1 Sensor 1 is behind the engine before the main catalytic converter (Figure 4). The two other sensors are located after the catalytic converters.
Is bank 1 sensor 1 upstream or downstream?
upstream
The bank 1 sensor 1 (upstream) O2 sensor is on the passenger side on or before the mini catalytic converter. The bank 1 sensor 2 is further down the exhaust pipoe after the cat.
Is bank 1 sensor 1 on the driver side?
The real truth is that you can't simplify it and say that bank 1 is on the driver's side or vice versa because different engines can have cylinder 1 on different sides. We drive on different sides also, so it's just really confusing and misleading to guess which side bank 1 -2 is.
Where is the bank 1 converter located?
When the engine has two banks of cylinders (as in a 'V' or flat layout), the catalytic converters located on the side of the engine with the number one cylinder are referred to as the bank 1 converters. The bank two catalytic converters are on the opposite side.
Where is the bank 1 sensor 1 on a Lexus RX350?
Understood, so bank 1 is the rear bank on the engine so the one closest to the windshield and sensor 1 is the one upstream of the catalytic converter so its closest to the engine. Its not very visible from under the hood.
