If one is out of whack, of course it can throw an A/F ratio off, even though there is what I like to call a default mode. A little too rich and you can kiss the other O2 sensor goodbye.

OK well just came on to type the same thing with my CEL and VSC lights. I will go to Auto Zone tomorrow and post the codes here and hopefully some (cough cough LexMex ) can help me out.
Car has been perfect until Saturday morning these lights came on, its a 01 and I have been freaking out since.
Hopefully post some codes tomorrow evening.

Check to make sure the air filter housing is completely closed. Last year after I changed my air filter, the CEL and VSC lights came on. I did not connect the two, and took it to the dealer. They charged me $60 to tell me that I had not completely snugged my air box after putting a new filter in. Don't know what the connection was with the VSC, but it turned both lights off.

Well yesterday morning the lights were gone after 2 days of being on. now they still off as of this morning. Does anyone know if I go to autozone if they still can tell what it was. And where is the air filter box to look for that?

Sorry for my late response...just got back from a trip tonight. If the lights went out by themselves, an OBDII code reader (as exists at AutoZone) should be able to pull up the old codes that were stored, even though the CEL no longer appears.

replacing the under the car sensor was a nightmare, the bad o2 had to be torched off then the manifold had to be rethreaded
dont attempt this unless you have a lift and torch

And thier back
I didnt know that Auto Zone could pull the codes of the lights werent on so I didnt go but now am forced to do something. Once I get the codes I will post them.
I think I was ready to ignore the fact that they ever came on since the car seems to be running just fine.

OK P0128 was the code and here was the explaination
Check coolant level
Thermostat defective
ECT sensor defective
So I bought the thermostat and ECT - are they easy to install ? Help me if you can, any advice is appreciated. It was $50 for the two parts ..... so hopefully this works
Also I actually noticed my car was running cooler than it usually does.

I have changed out the thermostat to a TRD one back in late 2005. Not the easiest thing in the world to, though it is more easily accessible given it is on the right side of the engine block.

Sounds like I will be bringing it to my mechanic then. Is this something I should take care of right away? I have been driving around for 2 weeks or so now with this.....

As far as how long you can go on, I would not want to chance this more than a month. Keep in mind, that when these CELs occur, that there is a default mode in these RX300s, but engine parts don't always care and can and will fail.

Ok thanks for the info, I will probably try and get it done this week. I would take it to Lexus but I just cant afford dealer maintenance.
Right now the current temp is running a little under halfway and usually it is about half or a little over half.
