Part #234-9051

I just got this code a couple days ago. I think I can change this myself.Thanks for the video.2008 rx350 with 135,000

Thanks for watching, David! It may be a bit challenging to get to, especially since one of the O2 sensors on your RX350 is located towards the firewall. It is not as easy to get to. The one on the front of the engine may be a bit tricky too. Good luck! Let me know how it goes! Also, be sure to check your fuel cap. Sometimes a faulty or loose gas cap may throw this code.

@@MaximumDIYGarage I finally got the sensor out and the threads came out with it so now I have a real challenge now 😞

[@MaximumDIYGarage]

Wow, hopefully the threads inside the exhaust manifold are fine

Great video! Thanks

[@MaximumDIYGarage]

Thank you, Michael! I’m glad you found it helpful! I have a few more GX videos on the channel.

When you add an 04 Lexus gx470 to where it says “check if it fits”. It says that this sensor is not compatible. Any word on that?

[@MaximumDIYGarage]

Yes, this may be because 2003-2004 were non-VTTi engines, so emissions settings are different.

We had the bank 1 Sensor replaced, and the dash lights are still on. ???

[@MaximumDIYGarage]

Hook up a code reader and find out what code is being displayed. You can go to any Autozone, Advance Auto Parts or O’Reily’s to get your dash lights read for free

@@MaximumDIYGarage Thanks, we did and they said to give it a week or so and go out and do some highway driving.

[@MaximumDIYGarage]

Hopefully that will do it. It may also be helpful to disconnect the battery for 1 to 3 minutes to help reset the computer

[@MaximumDIYGarage]

That works too if you can get to the O2 sensor!

[@DericEvansComedian]

@@MaximumDIYGarage ain't no if...... IT'S WIDE OPEN SPACE ON BOTH SIDES

[@MaximumDIYGarage]

Great tip!

[@DIYNorth]

that looks like a bit of a pain to get at.

[@MaximumDIYGarage]

You are correct! The most challenging part was accessing the harness and unplugging that. Still, as you know, this saves you a boat load of cash if you DIY, so it’s definitely worth the time and effort!

[@wallysordo9930]

Can you access the sensor from below?

[@MaximumDIYGarage]

I did not try that, but I suppose you can.
