I've read the threads above and will take the car to an auto parts store and have the codes read. Everyone seems to be referencing a "button" for the trac light. I can't find one on my 2004 Lexus RX330. The car has 195,000 miles on it, and continues to run great. I've been told that my car will automatically fail its' next smog test in Colorado if the check engine light is on. I'd prefer to avoid the Lexus dealer and a couple of $180 oxygen sensors, if possible. Happy to do the battery reset, if anyone believes that actually works. Thanks.

 

Try asking your question in the RX forum. (This one is for the 1st gen GX)
Good luck getting your problem fixed.

I have a 2003 Lexus GX 470 can somebody help me with a DIY replacement of knock sensors. The only DIY I have found is for a rx 300, and that is a 6cyl.

 

Hope this help.

 

Can you start a new thread on this?
