Check engine and TRAC OFF light stays on

Hi,

I have a 93 GS300 and these two warning came on as I was driving. Before bringing it to the dealer, I want to learn more about these warning lights. Is this an ABS problem or traction control problem. If anyone has this problem before, please kindly let me know what the problem may be and what I can expect as far as the repair bill is concern.

Thanks in advance for your assistance.

you need to take it to the dealers as soon as possible, a few people in this sight had had that problem including me. Some people said it was there brakes but the majority of the people blamed it on the TPS ( Throttle Positioning Sensor ) and it had to be changed. Make sure they change the whole sensor and not just clean it off or whatever they do, its too bad lexus doesnt have a writeup for it yet alot of people have experienced the same problem. If the problem presesists like mine did then ask for there master tech. to run a test on your main computer as they did with mine and change the whole unit out. Now if the problem still presists then they have to change out your whole throttle body and that would fix it

. Luckly for me the dealership covered my car under warrenty even though I have 90,000 miles and numerous modefications on my car, now thats what I call customer satisfaction
