A week ago, on my Lexus ES 300 (2001), "Check Engine" and "Trac Off" lights came on. This coincided with me filling the gas tank to the brim to round the dollar to be paid. Some websites suggested that the "Trac Off" is related to the gas tank cap not being tight. I cleaned the gas tank cap and the tank opening. However, both lights persisted. On the same day, when I turned on the car again, there was a hesitance, a stuttering to come on, like the battery was going down. Both "Check Engine" and "Trac Off" lights were still on.The next day, the car wouldn't come on at all. It sounded as the battery was dead. I couldn't even jump start the car. Usually, if the battery is completely drained, jump starting will not work. So, I got a new battery from Costco ($56.99) and put it in. (There is a $9 fee if you do not turn in the old battery). It took 15-20 seconds of cranking to get the car started. Once it was started, the engine sounded fine and the RPM was normal. The "Check Engine" light was off. However, the "Trac Off" was still on. I cleaned the gas tank cap one more time. The next morning, when I turned the car on, there was no problem at all. It came on instantly as it used to be, didn't have any warning lights, and drove smoothly. The gas tank cap getting dirty and the battery being down are unrelated things, which just happened on the same day. I do not know which one caused which warning light to come on though.

once you replaced the battery you reset the computer and cleared all the error codes, causing everything to appear normal again. mine did the same thing and progressivley got worse. had the dealer hook it up and they told me the throttle position sensor was bad. this is located under the hood on the drivers side of the throttle body, part is $60 through toyotaparts.com.

The same thing happened to me on my 2004 IS 300. The first year that I had the car, the "check engine" and "traction off" lights began flashing. I drove straight to the dealer. Since the car was under warranty, there was no charge for replacing the part that caused the lights to flash. Now, it's happened again. This time, I will be charged for fixing the problem. I'm hoping that it won't be too expensive, as I've just spend quite over $500 to have a new key made (recently, lost my keys). I had heard that leaving the gas cap loose could cause this problem. Right away, I checked the gas cap. It was on tightly. So, that couldn't be the problem. I'm wondering why this keeps happening???
