My 1999 Lexus ES 300 appeared having the same problem that you guys were talking about. The check engine and TRAC OFF lights stayed on for a while. After searching the web and reading a few of your postings, I got under the hood. To my surprise, the black hose behind the air filter did get disconnected. I simply reconnected the hose, and disconnected the battery for 15 minutes. Voila! The warning lights were gone! Thanks everyone for sharing the experience.

I am keeping my fingers crossed that this is the problem.
Right after I got it back from putting in new engine (due to oil sludge,I now learn) the Check engine and trac off lights came on.
Brought car back and
I had dealership check the code for these two lights being on &
the code says to replace solenoid for tranny ($600-$1000),
maybe the air filter hose has been disconnected.

I have an '01 Lexus RX 300. The VSC and TRAC OFF lights came on the dash. No manual! So, I found this forum and felt I had the problem solved. Took all this posted info to my mechanic (to save time/money) and after checking things out, he said that the hose and filters were OK . . . . that one of the Oxygen Sensors was bad/out/mal-functioning . . . . that it needs to be replaced ($350.00) . . . . that continued driving with a bad oxygen sensor will affect the fuel mixture and probably get lower mileage . . . . not dangerous.
Has anyone had this problem with the VSC and TRAC OFF lights???
AND . . . . consequently, we unplugged the battery (as suggested) . . . . replugged . . . . the lights came back on once . . . . then, not again . . . . BUT, SINCE REPLUGGING, the electronic data on the dash has been inaccurate (i.e., 25 mpg)!!! Anyway, no manual!
Has anyone had this (2nd) problem with unplugging the battery and electronic data display???
Any help would be GREATLY appreciated. Thanks in advance.

#34 of 73 Lexus RX300 using oil
May 11, 2010 (9:05 am)
I have noticed that my vehicle has to have oil added every time I fill up. I check it & its low, some times very low. Its not showing leaks on the ground. Any suggestions?

As wwest mentioned, it can also be an indication that the gas cap was removed and then replaced without refueling or the gas cap was left not fully tightened after refueling.
I solved my initial occurrence by reconnecting the hose behind the air filter cover. But a year later, the same lights came on. Refilling the gas tank, tightening the gas cap, and resetting the lights by disconnecting the battery for 15 minutes did the trick...

I have same problem from last night. Is it safe to drive for a few days until my husband can reconnect the hose and disconnect the battery?

Only if you're CERTAIN the CE is the result of the gas cap or air intake hose.
CE can be something much more serious.
