Coolant temp sender not working -- and -- Intake air temp sensor quirk? 140-160

D-Jet coolant temp sensor is at FRONT of head, next to aux air valve.
2 Wires from it, I believe, to ECU.
Sensor at back of head is for gauge only.
They are entirely separate functions.
Sensor below #4 exhaust port is thermal timer switch.

If D-jet collant sensor is shorted, either full rich or toally lean, I can't remember. Air temp sensor has minor effect.

It's probably the FRONT collant temp sensor that is disconnected.
