What is your question?
I was told after they did the diagnostic that there was a problem with bank 1 and bank 2 catalytic converter and that if it had to be replacd it would be about $2,300. Is there any possible way that the problem could be anything other than that? My car floats like a boat and runs great. I've put about $850.00 in the last 3 or 4 weeks in maintenance and repairs and the whole time my car has run fine. There is no rotten egg smell and I haven't had any trouble starting my car.

Catalytic converters are federally mandated to be warranteed for 8 years or 80 000 miles. If you are still within that, then they are a warranty item. Exhaust leaks, and faulty oxygen sensors can also cause this. Faulty catalytic converters on a high mileage vehicle, however, are very possible. There does not need to be an odor, since sulfur has been essentially eliminated from gasoline. VSA and TRAC is the vehicle stability control and the traction control. A problem with one, will disable both, and illuminate both lamps. The traction control may be deactivated by a switch on the lower left of your dashboard. Switching off the traction control will also illuminate both lamps. Make sure the switch is in the on position. If it is, then you will need your vehicle scanned to identify the problem in that system as well.
Great answer by "devilscap4", I would plug in a scan tool and look at O2 sensor patterns especially the rear sensors to see if they are oscillating a lot or relatively flat as they should be if the catalytic converters are good.
You already have 2 excellent answers from 2 great tech. Here is what I'd like to add: Was your vehicle manufactured between February, 2003 and April, 2003 and your VIN range is between 40001284 and 40006137 or between 40001700 and 40012110 ?? If yes, there is a recall from Lexus and they will replace the converters for free, even if you are out of the 8 years/80K warranty. Recall / Campaign #: SSC3LE Let us know what happened. Zee
Hello, have you fixed the problems? I have 2004 RX330 and same 3 lights on: check engine, VSA, TRAC off. The diagnostic is the same a problem with bank 1 and bank 2 catalytic converters. One mechanic told me try the sensors first another one told me to change the converters. Do not know what to do. Thank you.
I just had the same 3 lights. One mechanic said it could be bad gas cap seal. He backed off and tightened it and the next day all the lights were off. They came back on a seek later after i got gas...so i tried go retighten the cap and the next day i drove it and the lights went off. Now today hi gdy about 1il out from home and the lights vome back on. But this the transmission stsrted acting up..slipping and switching gears irradically. I got it back home and switched cars,and hete se are at our eye doctors office eaiting 4 our appointments. I suspect a vacuum leak. Tell me if I'm wong!
