After replacing what I thought was everything that has to do with the cooling system, I recently found out that there is another sensor that is below the distributor (93 civic coupe with D15).

Would this sensor have anything to do with my temp gauge not moving?

I know the temp gauge works (it has shot up before when my car did overheat), and I've replaced all the fuses and sensors associated with it (except the one mentioned above) but would just like opinions if anybody knoew if this has anything to do with the temp gauge not going to the halfway mark during normal everyday driving.
