Pinkskunk

First and foremost, i would like to thank all those you helped out the fellow members here with their problems. your help have lead me to this far, as oppose to the dealership which would run me close to thousand of dollars.

after reading some of the postings, i brought my car to Autozone and have them read my VSC/Engine light on.

th outcome is:
Code P1155
Bank2
Sensor1

The guy gave me the part number as follow:
Bosch O2 Sensor O.E. type.

Fit OE
Type: Wideband A/F
Wires:4
Part#: 15217
Retail: 169.99

--------------------------------------------------------
i read this site and it seems to me my 2001 RX300 model code P1155 is the A/F Sensor.

i have 2 questions for you:

1) Where is this sensor located? is it in the picture i attached?
2) Is that the rigt part number?

Welcome to ClubLexus!

If you do a search, you'll find several postings warning people to use OEM Toyota/Lexus sensors, and not other brands such as Bosch. That's what I would do.

I am the second person to tell you search or at least scroll through the first page. This one can be easily found if you do either.

Ands I am the 3rd one. You can buy the real deal (OEM) online for less than the BOTCH, and you don't have to worry about whether it's gonna work right or not!
