Coolant Temperature Sensor / Switch HVAC: Description and Operation
The engine coolant ambient temperature sensor is located on the heater inlet line between the engine and the heater core. It detects coolant temperature
and converts it into a resistance value which is then input to the EATC unit. After disconnecting engine coolant ambient temperature sensor harness
connector, measure resistance between sensor terminals (1) and (2), using the table.
