★ Top Answer
The 2018 Subaru Outback has its ambient air temperature sensor located at the front of the engine bay under the hood. The coolant temperature sensor, also referred to as the engine coolant temperature sensor (ECT sensor), is responsible for measuring the temperature of the coolant in the cooling system to monitor the engine's heat output and prevent overheating issues. Signs of a faulty coolant sensor include overheating, starting problems, rough idling, illuminated check engine light, and malfunctioning electric fans. Replacing the engine coolant temperature sensor typically costs between $120 and $160, with labor around $80 to $100 and parts priced at $40 to $50.
