COOLING FAN SYSTEM (1ZZ±FE/3ZZ±FE)
ON±VEHICLE INSPECTION
HINT:
It is normal that the cooling fan sometime rotates when the ignition switch is turned from ACC to ON.
1. CHECK COOLING FAN OPERATION WITH LOW TEMPERATURE (Below 94.5C (202F))
(a) Turn the ignition switch ON.
(b) Check that the cooling fan stops.
If not, check the cooling fan relay and engine coolant temperature sensor, and check if there is its connector
disconnection or circuit open between them.
(c) Disconnect the engine coolant temperature sensor connector.
(d) Check that the cooling fan rotates.
If not, check the fuses, cooling fan relay, ECM and cooling fan, and check for short in a circuit between the
cooling fan relay and the engine coolant temperature sensor.
(e) Reconnect the engine coolant temperature sensor connector.
2. CHECK COOLING FAN OPERATION WITH HIGH TEMPERATURE (Above 96C (205F))
(a) Start the engine, and raise coolant temperature to above 96C (205F).
HINT:
Coolant temperature is detected by the engine coolant temperature sensor on the water outlet.
(b) Check that the cooling fan rotates.
If not, replace the engine coolant temperature sensor.
3. INSPECT COOLING FAN
(a) Disconnect the cooling fan connector.
(b) Connect battery and ammeter to the connector.
(c) Check that the cooling fan rotates smoothly, and check the reading on the ammeter.
Standard amperage: Approximately. 8 to 12 A at 20C (68F)
(d) Reconnect the cooling fan connector.
