I know it's been posted before. I am in an urgent situation and in need for a quick answer...hope someone can help me out ASAP.

Me and my friend is installing the Borla full cat back exhaust on my car. We use the proper O2 sensor tool and PD buster around the sensor to ensure we can get the sensor off without stripping it.... However it still happened....the right side O2 sensor got seize up from factory, when we get it off. The thread stripped a little bit and now it won't fit in properly.

Where can I get the Oem O2 sensor ASAP. Does the Lexus carry it? Or autozone etc?

And how do we replace it, it seem like the wire come in one piece and go inside the car....

This is Urgent....I really appreciate the helps.

 

Just found the O2 part # it's DENSO Part # 2344521....
Anyone can provide me a DIY on how to replace it? joeZ mention it has to remove the carpet I believe. Thanks.

 

Glad you found it, but I'm not sure where it leads to. Hopefully someone can chime in quick,for you. Best of luck.

 

If you can't figure it out tonight, just zip tie that thing up in there. You'll have a cell, but I would think the car should run fine until you have an answer.

 

Have it over-nighted or 2day' from sewell parts.

 

Thank you for all your guys reply. We are able to put it back on the car somehow....but it's not tight.... I drove 15 minutes to home, so far no check engine lights. I am planning to call AutoZone first thing in the morning...i was told they have a warehouse in my area.....so hopeful i can get the Sensor within 2 days before my friend PCS to AZ.

As for now....I am hoping to have someone to show me how to replace the whole sensor, a DIY or a diargram from service manual etc.

Thanks again for all you guys' help! I have to go to sleep now....long day today

Ordered my O2 Sensor from AutoZone for 108.00; will be here tomorrow.

Anyone can help with the DIY?

 

Might have to splice into the existing wire as I'm sure it runs all the way to the computer. I don't recall how the wire is connected to the sensor. How does the sensor come from AutoZone? Is there a wire coming out of it. I need a picture so I can remember what it looks like.

Edit: My bad, looks like there's a plug on the end of the wire, so I would assume you just have to figure out how to get to it. Someone should know how to do this.

$108.00 seems cheap. CL price on Sewell is $139.36.

 

Ray, this DIY isn't specific to the IS-F but it should still help you along the process - let me know if it helps at all - also check your PMs.

The O2 sensor plug ends are located under the interior carpet floor, right next to the trans tunnel....

There is one on the drivers side and one on the passenger side..

Visually speaking, it would be under your leg/calf area..


Also, the Lexus / Toyota OEM Part #: 89465-30730 & Denso Part #: 234-4521

Yeah, I *JUST* had it done. Just pull the rug away from the center console and you'll be able to see the plug. Screw the O2 sensor in and then fish the connector through the hole and you'll feel it coming up from under the carpeting. Like Joez says, it's by the calf area on the side of the tranny tunnel. No clips to remove and nothing to unscrew. Just pull the carpeting away from the tunnel a little. Once you get it, plug it in. Then just put the carpet back under the plastic edge. Plug the boot back in the hole. Too bad I threw away my other sensor - I could've overnighted it to you. I wanted two brand new sensors installed at the time of my new exhaust.

 

Ray the DIY i sent you explains the carpet removal step by step

 

THANKS FOR EVERYONE'S KIND HELP!! I will try to do that tomorrow if i am staying up late at work like today!

1 CAR 1 LOVE!!!

 

Here's a picture of the passenger side. The driver side is the same but the pedal gets in the way a little.

 

Just put your fingers under the edge of the rug and pull. Simple as that. And when done, stuff it back in. You'll need a guy pushing the wire from underneath while you're on top looking for it.
