Steve Brotherton has reported that the cold start valves duty is very short-lived. Used only at initial start-up. I believe that if your present climate is warm enough, it may not be a factor at all.

You'll need juice going thru the circuit to measure pressure(voltage). Check the sensor in parallel.

Go to the SEARCH facility and key in:

coolant temp sensor

in the search field. Click on "titles only" - 7 hits. Good info between all 7 posts.
