Hi,

as I had a problem with the oxygen sensor on my 2003 1gen RX300 I am stuck now with VSC light on.
I do remember I saw somewhere step by step instructions to do a zero point calibration on RX300 - similar to this: https://www.toyota-4runner.org/5th-g...libration.html - not sure if it is the same and I do not want to shortcut wrong pins... :-)

Do you have something of this sort for our RX's...?

My oxygen sensor seems fine... It fell out of socket during winter travel to Cracow.
Since it was New Year period all garages were closed.
I've done an additional 250 miles with it hanging below the car (at first I thought I only have a hole in my exhaust - only when the "check engine" light came on and it started to knock from the bottom I realized what has happened) and... surprisingly it seems to be fine.
The socket is fixed, the sensor is back in, the car is quiet again, check engine light is off and not coming back... so all that is left is to switch off the VSC light too.

Thanks for instructions ;-) I've lost them somewhere on my PC

???? There was a reply here (between my posts) with the link... and it's gone :-(

All sorted.
In the OBD socket - top row from the left 3rd pin
bottom row from the left 5th pin.
Car levelled, ignition on, few short connections with a bit of wire... VSC blinks fast.
Ignition off, wire out - Bobs your uncle, all is fine VSC light is OFF.
