^^ Sounds like the original installer jacked up your O2 sensor....... !!!

You will have to buy a new one or try to find used one at a junkyard..

or

maybe check with Tommy to see if he can repair the damage sensor or wiring, since they found the one with the problem.
"Low voltage on LT Rear o2 sensor. Twisted, Excessive Resistance"

Sorry to hear the bad news..

Hey Mark (This is Warren btw). It was nice meeting you at Tommy's place the other day. I'm sorry to hear about the o2 sensors issue. Like Tommy and I mentioned, since now you have concrete evidence from the dealer that the o2 sensors are bad, you may want to go back to the place where they installed and see if you can come to a resolution to get it fixed. There's no guarantee they'll reimburse you, but I would give it a try.

You may have to be persistent on getting some sort of reimbursement because according to yelp, it looks like these guys have a record of screwing up people's car and trying to charge more to get it fixed, so be careful!: http://www.yelp.com/biz/promax-motorsports-alhambra

 

do you have to tools to wiggle the o2 sensor?...bring it back to the first shop ask them for help..they may charge you cheaper a little bit.

 

^^ Ouch to those Yelp Reviews....

dude mark, i didn't realize it was you when i posted. WTF man why didn't you come to your friends and have US do the install correctly for you? instead of some shop who honestly doesn't car about your car.

 

Just went to promax and fight for my right. but they refuse to help me out and do any reimbursement and replacing service for me.
They claim that my o2 sensor was rusted and hard to remove so they send it out to other shops for unstallment and charge me 15 more dollars for it and still end up like this.
So what do i do now?

 

I have found two website with cheaper o2 sensor but not sure are those the one that will fit. Please check it for me every one!

Hey Mark, I found this post on my.is (http://my.is/forums/f115/oxygen-sensors-faq-334479/). It's a thread about o2 sensors, and they list vendors that sell oe products. Since we use Denso, here's the site: http://www.densoproducts.com/results...ctCategoryID=2. I've never bought from them personally. Around $90+ship a piece.

As for those A-holes at promax, I'm sorry to hear that they're not taking responsibility for their mistakes. As you read from those Yelp reviewers, these guys try to blame you even though they screw up. I would write a bad review on Yelp and even file a complaint with the BBB (Better Business Bureau): http://www.la.bbb.org/ComplaintInformation.aspx

You are looking for #4 below .. Rear O2 sensor..

List price shows $177, but you should be able to find it online for around $125 (for one) from a Lexus dealer...



Good Luck

Joe Z

 

Do you know which online lexus dealer sells at that price? i have been search around but no luck.
Here is the link that a member provide from denso website: http://www.densoproducts.com/results...ctCategoryID=2

Do you think this is the one?

Mark

 

Just brought the o2 sensor direct from denso website. let's see what's up.

 

Did you get Denso part # 234-4521 ???



I guess you can't go wrong for $92... Also, I guess you confirmed which one is the problem... right?

I strongly recommend for Tommy to install the new sensor once you get it..

Joe Z

 

GL with the install. I hope you get that CEL fixed. +1 for Tommy

 

when u going mark? We can hang out at Tommy's again. ahhaha
