This video shows the replacement of air/fuel and O2 sensors (commonly all referred to as O2 sensors) on a 2004 Lexus RX 330. The engine is a Toyota V6 with the code 3MZ-FE. This engine comes in various vehicles including Highlander, Camry, Solara as well as Lexus RX 330 and ES 330. No product sponsorship or endorsement.
Tools needed include:
Ratchet, 3/8 (1/2 inch preferred where it fits).
12 and 10 mm sockets to remove plastic in the way.
A selection of socket extensions.
O2 sensor sockets: I used a Lisle 12100 (similar to a Texton) and a Powerbuilt offset 648691. Powerbuilt and OEM also make some nice sets.
Jack and stands.
Your favorite penetrant.
Denso parts:
Air/fuel sensors: 234-9042
located before the cats
O2 sensor (front of engine): 234-4168
O2 sensor (rear of engine): 234-4509
Part numbers may differ slightly with other models.

    I heard there’s something called “ adaptation values “ which you should do it with your OBD after replacing any oxygen sensor so they can read the new date but not the stored old data. Any idea on this one ? Great video by the way 👍🏼

    Thanks for watching! I have heard of the term with certain codes like P2097. Whenever I have replaced sensors on Toyotas I let the PCM figure it out and see if it resets. If not after some short drives, I reset it with my scanner.

    @@costantineyoussif6679 those two codes point to the upstream pre-cat air fuel sensor on the left side not the downstream. If it were my vehicle, I would replace that particular sensor and see if that solves the problem. You should only see smoke at start up on cold mornings. Also need to check the coolant to make sure the heads and gaskets are ok.

    Just my opinion, more emission issue than drivability, but I don't like having the codes. If it were me, I would try a cat cleaner in the gas tank first. If that doesn't work, replace the sensor. If that doesn't work try: kzread.info/dash/bejne/pmiBpbewkcjXcZc.html

The worker who has really helpful told me that it was probably an 02 sensor. Any thoughts as to what it could be? Im going to the mechanic shop two days from now. Thanks!!

    The combination of those codes usually means you need a new gas cap. I would look at that, check the vacuum lines, and probably a PCV valve.

    Maia, good question. I would think an experienced mechanic would take 2 hours tops. I purchased the Denso OEM sensors from Amazon for right around $200. I understand that mechanics have to make it worth their while, but if it were me, I would check some other estimates.
