Excessive coolant consumption
 
Is it possible that a faulty ECT sending unit will cause excessive coolant consumption? My car is taking too much coolant I have to refill coolant every 3 months and I know the ECT is bad. Is getting my fixed but the question still in the Air

Is it leaking where the ECT inserts into the cylinder head? Do a coolant system pressure test while engine is cold. If an ECT sesnor is leaking it's possible it seals up (expands) at operating temp and leaks as the engine cools down (contracts). How much coolant are you losing per day, week or month?
Has the engine overheated?

Only if it's the source of a leak.

Wait......There are 3 temp sensors, which one is bad? If a Radiator fan temp switch fails, that can cause overheating which could cause coolant loss.

doesn't overheat it goes above normal temperature when idling but as soon as you start to drive the temperature goes down. but over time will consume all the coolant

the fan is wired to t will be on all the time and plus the radiator and fan are technically new just above a year old and I don't mistreat the car
