This video goes over how to replace an oxygen sensor on a 2007 Lexus ES 350 with a 3.5 motor. This should be the same process for any 2006-2010 Lexus ES 350 with the same motor. An oxygen sensor is used by the engine's computer to determine the correct air to fuel ratio needed so that the engine will run efficiently. There are oxygen sensors before the catalytic converter and sensors after the catalytic converter. The ones before the catalytic converter are called upstream and the ones after the converter are called downstream. This Lexus ES 350 has four oxygen sensors, 2 before the catalytic converter and 2 after the catalytic converter. This can vary on different models and manufacturers. Some vehicles can have as many as six. You can drive a vehicle with bad O2 sensors for a period of time if you can put up with the poor performance and decreased gas mileage, but over time it will hurt the longevity of your motor and cause failure of your catalytic converter because your motor wasn’t running efficiently as the manufacturer intended. The most common signs of a bad oxygen sensor are a check engine light, decreased fuel economy, hesitation, rough idling, or misfiring.

Hello sir. I’m getting a P0051 code on my 2004 ES330 after fixing an exhaust leak. Do you know the location of that sensor?
I’m not sure if it’s the one in front of the engine or the one before the cat on the exhaust.
Front of the engine, Its the one before the Cat.
(P0051 code) HO2S Heater Control Circuit Low (Bank 2 Sensor 1).
A ES330 has four O2 sensor's, two on Bank one and two on bank two.
Will the check engine light turn off itself after replacing the sensor?
Not always , if you don't have a scan tool disconnect your battery which causes the ECU to reset the check engine light which is equivalent to a hard reboot on a desktop computer.
Great video.
What about a Bank 1 Sensor 1 for an 07 ES 350 Lexus?
Same basic principle, but on the backside of the motor by the firewall, it's the first oxygen sensor.
@@TheAutoTeacher It looks so manageable that I may try to do it my self. I recently had my Catalytic converter replaced and afterwards. My check engine light still on w/ this code. My mechanic wants to charge $140 for /labor.
my lexus es330 2005 got diagnosed with an O2 sensor code and i was wondering if that can also be the cause of my steering noise when i make a full turn both left and right
No, that would have to do with a breakdown of your power steering fluid or a bad rack and pinion .
@@TheAutoTeacher appreciate your response! but wow thats even worse then i thought :(
what is the oem part number
For this Lexus part number 8946707010. But I would call the dealer with your Vin number to make sure you get the proper part.
I changed out this exact sensor your pointing to in the beginning of video.
And now my back mufflers sound louder than before .
Only thing I noticed was the O2 sensor was a bit shorter than the old sensor it had .
Is this normal?
The Oxygen sensors should look exactly like the old one that you remove and it's always a good idea to use whatever was recommended by the manufacturer. Replacing the oxygen sensor will have nothing to do your vehicles exhaust being louder.
Hello, my friend, I am from Saudi Arabia, and I have the same car, and I have the engine check mark, and I checked the engine, and I got a code P0420. Is this code the same as the problem that you changed now, or is this code for another sensor? Please reply please
No, we had a PO151 which means that O2 Sensor Circuit Low Voltage (Bank 2 Sensor 1) has been detected.
There are many variables that could cause your PO420 code ,it can be caused by various things such as a malfunctioning catalytic converter, a clogged air filter, a vacuum leak, spark plugs or O2 oxygen sensors that are beginning to fail .
Great video! I feel a lot more confident about replacing it myself now. Do you know the torgue specifications for the O2 sensor, or do you just tighten it by feel?
Thank you, by feel.
I just had bank 1 sensor 1. I have no idea where it is. Could you possibly shed some light on the location please.
Bank one, sensor one is backside of the motor by the firewall. It's the first
one from the top .
Can you also do the downstream as well
Sorry, the customer already picked up the car.
it said "check vsc" so i though it had something to do with suspension system or sum lol
Yes, but whenever a Toyota/Lexus throws an engine code, it will also disable the VSC light and triangle. Fix the reason for the PO code and your VSC light should go off.
Thank you. Ver informative and to the point.
You're welcome!
I got check engine light and slip indicator light
Was told its an electric issue
With the 02 sensor im guessing its the oxygen sensor or whatever.
Its causing slight issues when my transmission/acceleration.
Is this an expensive fix?
Mines a 2010
What are your PO codes ?
@@TheAutoTeacher not sure I have someone on their way he is going to scan for data
I know the car has been picked up but to change bank 2 sensor 2 would that be from under the car or from the top?
From under the car.
Would the bank 2 sensor 1 be in the same location on a 2019 Lexus es350?
yes
@@TheAutoTeacher thank you :)
Where would bank 1 sensor 1 be?
Sorry no video on that one. The other side of the engine, by the firewall is 1,3,5 and it would be the one before the catalytic converter.
Does the brand really matter?
Unfortunately yes, if you buy something unbranded for a third the price you can't expect the quality and longevity that you would get from a OEM part.
Good video what about po138
Bank 1 Sensor harness is open or shorted or Bank 1 Sensor 2 circuit has poor electrical connection. But most likely it's a Faulty Oxygen Sensor Bank 1 Sensor 2 .
@@TheAutoTeacher thanks for the response
I’ve got similar issues but now to replace the sensors , they all different mounting so I don’t know which is for which
What PO code do you have?
Hey hi. I got that code on my 2007 Lexus ES350 (same color than yours): P0051 H02S Heater Control Circuit Low (Bank 2 Sensor 1).
I ordered the ox. sensor, but I won't be able to install it until few days. Is it bad to drive with a defective oxygen sensor?
Thank you.
You can drive a vehicle with bad O2 sensors for a short period of time if you can put up with the poor performance and decreased gas mileage, but over time it will hurt the longevity of your motor and cause failure of your catalytic converter because your motor wasn’t running efficiently as the manufacturer intended.
@@TheAutoTeacher Ok, I understand. Thanks a lot for your help. I'm supposed to get the sensor tonight and will have it installed as soon as I can.
@@TheAutoTeacher hi, does that one help in gas mileage because mine is getting the worse gas mileage have changed the plugs still the same now m getting p0355 E coil will changed it next week planning to changed the 02 sensor also
@@TheAutoTeacher yeah I ain't driving mines until replaced for the fact it's loosing gas rapidly
