This is the water thermo sensor code. Looks like I need to replace the sensor and while I'm doing that I'm going to replace the thermoswitch with a Miata one i got.

From search it said that the thermosensor is the top sensor and the thermo switch is the one underneath it on the back of the water pump housing. Is this correct?

What is the part number for the water thermo sensor ( water temp sensor )? I've read that it is # NF02-18-1840 , but then I read a post stating there are 3 variations of this p/n: #1, #2, and #3. Are there varying numbers and if so which one is the thermo sensor?

Summing it up, where are the thermo sensor and thermo switch located, and what is the p/n for the thermo sensor. Thanks for the help.
