My '95 GL's CEL light comes on because the insulation is gone on the harness leading to the coolant temperature sensor. I have to re-position the wires so that they don't touch and everything is fine. I know it is this problem because it makes the electric fan on the radiator come on. This morning the fan and CEL came on as soon as I cranked the engine and it was 34 degrees outside.... I don't think the engine was hot yet! I moved the wires so they wouldn't touch and the fan stopped and the CEL went off.
