1.9L SATURN "S" Series: Description

A fan control relay is used by Powertrain Control Module (PCM) to control engine cooling fan operation. Engine cooling fan is turned on or off by PCM dependent upon engine coolant temperature, vehicle speed or A/C request. Under high ambient temperatures, fan may run up to 4 minutes with key off.

Under normal operating conditions, cooling fan motor operates whenever Engine Coolant Temperature (ECT) is greater than 222°F (106°C) or A/C relay is commanded on less than 70 MPH. Cooling fan motor will turn off when temperature drops less than 212°F (100°C), cooling fan motor can run up to 4 minutes or until ECT drops less than 225°F (107°C) with ignition off. If DTC P0117 or P0118 is set, PCM will command cooling fan relay on to protect engine and transaxle until condition is corrected.
