It's caled a "Thermal Time switch" because it works against temperature AND time. When you run the starter motor power from the accessory terminal goes to the TTS. If it is cold enough the TTS will ground the circuit activating the cold start valve. The TTS also is time sensitive. There is an element inside that heats up during operation and after a certain period of time will deactivate the CSV so you can't flood the motor during excessive cranking. This is all in the Workshop Manual, see D:01:10. The CSV can ONLY operate during cranking except if you do the plug swap. If you DO do the plug swap you MUST quickly remove the plug from the CSV once the motor starts or you will flood it. BTW make DAMM sure there is NOTHING plugged in the hot start relay plug near the fuse block. If there is then the CSV could be energized at times other than cranking and that is not good.
