My low coolent light keeps coming on, but my coolant is not low. Is there a senser for the coolant.

yup, it'* in the passenger side tank of the rad.

Can cleaning the electrical contacts or something else simple be done to remedy this? Mine does the same thing.

same problem here

Since it one of those variable resistor type things, I'd bet so. Cross your fingers and hope?

My problem was my old, crappy coolant gummed up the sensor, and it always said I had coolant, when I didn't, but it also said I had coolant when I had some. A good cleaning is a very good chance it will fix your problem, otherwise it probably is a problem with the wiring.

I pulled the one out in my "92 SSEi, and cleaned the tip that is exposed to the coolant. It worked OK for a while, then started sending false low coolant signals again. I finally just unplugged it. No more warnings, false or otherwise.

You'd think you could get a replacement sensor somewhere. Can't be too expensive, can it?

If it were just a sensor it probably would be cheap, but it is a Module with three wires feeding it and probably a 10 cent chip in it. When I priced it at O'Reilly, I think it was over $40! I might consider replacing it if I could get one for $15 or $20, but more than that isn't worth it. I check my coolant every time I open the hood, and the radiator when I change the oil, and the temperature gauge constantly.

My check oil level light does the same thing.
Who needs these sensors anyway?
I always check under my hood. They are trying to idiot proof tooo much on cars today.
