Component Inspection (Cooling Fan Speed Sensor)
- CHECK COOLING FAN SPEED SENSOR
- Turn ignition switch OFF.
- Disconnect electrically-controlled cooling fan coupling harness connector.
- Rotate the electrically-controlled cooling fan coupling slowly with hand and check the voltage between electrically-controlled cooling fan coupling connector terminals under the following conditions.VOLTAGE SPECIFICATION
+ - Condition Voltage (V) (Approx.) Electrically-controlled cooling fan coupling Terminal 5 4 - 5V direct current supply to terminal 2
- Terminal 4 connect to ground
0 <=> 5 NOTE: The voltage is in waveformIs the inspection result normal?
YES: INSPECTION END
NO: Replace Electrically-controlled cooling fan coupling.
