Thumbs down 1992 Ford Taurus check engine light
Hello,
My friends 1992 Ford Taurus GL (3.0 engine) has a check engine light on. We have taken it to 3 diagnostic centers and they say there are NO codes in the computer to extract. We need to smog this car in CA, which cannot be done with this light on. I have NO idea what might be causing this light to be on as the car runs perfectly.
I have replaced the gas cap, main computer and throttle position sensor, but that is it.

If anyone has an idea what might cause the light, or what to trouble-shoot, please advise!

Thanks
