Hey All,

I went to get car smogged today, have engine light on, has been on for a couple of years now and have never had an issue with the car, or passing smog. I have a 2005 IS 300 with about 70k miles on it. The guy at the smog shop said was reading:

P0057 - Bank 2 / Sensor 2

Which I believe is o2 sensor. I called the local mechanic, and he said it sounded like about $150 in labor, and Lexus replacement part is $250.

After looking at some of the threads, that seems high for the part, I can't find the part number anywhere, but from what I have read is that Denso product for $60 will work just fine.

Any suggestions on strategy, should I get part, and then take to mechanic to install? Does his quote seem low / high?

Does anyone know the part number / what to buy?

Thanks so much!

Here's a list of O2 sensors from the Denso website (Denso makes the OEM toyota sensors).

Bank 2 Sensor 2 is the one under the passenger seat floor. It is the downstream 4,5,6.
Denso part # 234-4517

You can order the part here
https://www.densoproducts.com/Sensor...cts-c1318.aspx

Or search places like Amazon or eBay for that part # and compare prices.

His quote on the labor seems high, but they're probably factoring in the sensor being seized in there, so they have to blowtorch it for a while to get it out.

You can potentially do this yourself, if you have some tools, and oxygen sensor socket, a big *** breaker bar, and lots of penetrant liquid. And time.

My local Lexus dealer charges $150/hr

Awesome, thank you so much!

So the part looks like it is about $50, is Denso the brand that I want to go with? That's what I read elsewhere, how confident are you that replacing that sensor will make the P0057 error go away, and so I can get smogged?

I am annoyed / concerned that the mechanic quoted me $250 for the lexus part over the phone, and $150 in labor, how difficult is it to install / what do you think someone should be charging me to install?

Obviously not holding you to anything, just a rough opinion would be awesome.

Well, everything points to an O2 sensor problem. If the problem persists after the sensor is changed, then you would have something wrong with the ECU or the wiring harness. Normally, that's not the case with IS300s.

Labor is going to be hard, because depending on how much surface rust there is under the car, it could be as simple as buying an O2 sensor socket and getting under there with a breaker bar, or a trip to a Merlins where they put the car on the lift and blowtorch the sucker for 10 minutes straight

And yes, Denso is the brand to use. They make the sensors for Toyota.

I ordered the right part from Densoproducts.com.

Can I look and determine how much surface rust is under the car, and get an idea of roughly what mechanic should be charging me (just to make sure the quote they give me is not way out of line)?

What / where would I should be looking to determine surface rust

Thanks again, you are da man!

I guess you could, but either way you're still gonna have to pay what they charge you. They usually charge flat rates for jobs. Otherwise you're just going to have to shop around and find a place that charges a rate you think is fair

install yourself if possible. changing an O2 sensor is easy.
