So there are two signals produced within the sensor itself instead of being split off ? That could make it more tricky to troubleshoot should there be a problem. I recently suspected my CTS, but after troubleshooting, it seems to be OK. I don't have a heating problem, the dash temps appear normal, and the fans kick on at about the 3/4 mark on the dash. One thing that I can't explain is that when I disconnected the CTS, the fans immediately turned on. I read elsewhere on this forum that if the fans start after the CTS is disconnected, that indicates a bad CTS. Mine does that, but the cooling fans seem to be functioning normally.
