Ferrari Forum - View Single Post - What does the Coolant temp sensor do on a 308 QV on the recovery tank

JRV I am sure you know this one. What does it do and what does it send power to? I am refering to the coolant temp sensor for the CIS system on the recovery tank. Mine is a closed circuit when cold and open when warm. So it must divert power somewhere.
Here is where I get confused. I thought it was to tell the ECU open/closed loop but the 83' QVs have one and have no 02 sensor or ECU. Kind of a puzzling question. Any insight is appreciated.
