hello everybody, new lexus owner, sc430 pebble edition, i have a question, i recently got cel light on and vsc also on, plus that other light cant remember, ran obd scanner and got code p0031 h02 sensor heated control circuit low bank 1 sensor 1, any idea how to proceed? what could be causing this, is it the actual sensor or could it be something else?if its the sensor does any one knows if its passenger or driver and where its located? and if you have a part number, i tried for days on the web to search but no luck, thanks in advance, I love the car

 

I have this problem often. My mechanic suggested I go to You Tube and find a video to see how to reset. He said it is not difficult. With that encouragement, I searched and found this info. I am unable to post the link to the video, but the title caption is:

Re-calibrate reset the VSC TRAC on Lexus SC430

”Following the replacement of the O2 sensors on my wife's Lexus SC430, the shop failed to reset the VSC TRAC lights. I was able to DIY the reset using a paper clip. First, make sure the vehicle is on a level surface and the front wheels are facing straight forward. With the keys NOT in the ignition set the paper clip to the jump the appropriate pins. Then insert the key and turn the ignition to ON but do not actually start the motor. The VSC lights will flash consistently, meaning the system is being reset. You only need to see the blinking for a few seconds. Now turn the ignition off and remove the keys. Next remove the paper clip thus disconnecting the jumper. Start the car and the lights should turn off.”

 

this might be the video you referenced.
weird that you couldn’t post a link
jump pins 4&14 on the OBDII connector

 

Agreed. Thanks for posting.

 

Yes, the jumper hack still works as of 6-1-24. Thanks!

 

In Georgia they just do an emissions inspection.
