While on vacation (of course) the lambda light came on. It was very hot and humid 46 degrees C on the dash thermometer. The car is running fine, gas milage has not changed. I cleared the warning light by disconnecting the battery, but it came back. I bought an Autoexray code scout reader and it indicates that there is nothing wrong! No codes.

Does anyone have a diagram that would explain what triggers this light? The Haynes manual is usless, doesn't even mention the warning light.

Many Thanks,
