Check Engine light

2002 GS300 111K. Check Engine light just lit up while I was on the freeway. I checked the gas cap and it was secure. Next morning I drove home about 50 miles and the car ran fine with the light on. What might be the cause of this? I am going to call my local Toyota/Lexus mechanic to see how much a diagnostic will cost. What is a fair price to expect?

At this stage, I wouldn't pay anything to find out what the "check engine light" means, since some places offer a free check. I had the light come on and I went to a chain auto supply store that offers a free check. It turned out to be a minor matter that they could correct. The dealers, I understand, charge quite a bit just for the check that takes less than 5 minutes if you have the correct gizmo.

Dealer wants119.00 for check and local toyo/lex specialist wants 75.00 with that going to any reapirs needed.

The first thing to do is to disconnect the negative battery terminal for about one to five minutes, then reconnect it. That should turn off the "check engine" light. Assuming that works, then drive the car normally and see if the light comes back on.

Did your radio and seat settings come back after the battery was disconnected?
