Unhappy check engine light codes

I own a 2000 RX300 with 145298 miles. I'm the original owner and have maintained the vehicle very well. Just recently replaced the bank 2 A/F sensor 1(code P1150). My CEL came on yesrteday and I had Autozone scan the trouble codes and the results are BBE VAP System vent control circuit:BB1- Open or short circuit condition, BB2- Poor electrical connection, BB3-Faulty vent control solenoid. Can anyone shed some light on these probable causes and or solutions. The SUV is running fine and can't notice any performance issues yet. Thanks in advance for advice.

Does the AZ printout have the P codes on it. I don't know offhand if these BB codes do us any good. please post the P codes if you have them.

Default Check Engine light P Codes

You're right, AZ printout has a p-code number. P0446 Thanks for the heads up "code58". That was the only P-code.

Jack- The best advice I can give you is go to www.obd-codes.com It is a terrific site and if your willing to spend the time researching (stick with it, don't give up!), I can almost guarantee you'll find all the information you need. I just spent about an hour on there researching the P0446 DTC and IF you dig, it's all there. P0446 is "evaporative emission control system control circuit malfunction", If you dig, it will tell you all you will ever need to know about what are the likely causes of this problem. The blue highlighted at the bottom of the one page will all lead you to forums on the P0446 DTC. Too much to post here but it's ALL there! Good Luck!

Edit: Jack, do you ever "top off" your tank? It may be the problem, but even if it isn't, you'll understand why you shouldn't ever do it!
