Oil Temperature Sensor/Switch: Description and Operation

Fan Timer System:
When the engine oil temperature is above approx. 1O5°C (221°F) after the engine is stopped, the condenser fan goes into operation to cool the engine for a maximum of 3O minutes.

When the temperature falls below approx. 9O°C (194° F), the fan is stopped.

The fan motor runs at a low speed to decrease operation noise by using a resistor to the motor voltage.

The oil temperature switch is located on the rear cylinder head cover and the fan timer unit is located under the PGM-FI ECU.

If necessary, the fan begins operation 5 seconds after the ignition switch is turned off.
