REMOVAL
• Drain the engine coolant. (!2-20)
• Remove the air cleaner chamber and throttle body. (!6-13)
• Disconnect the ECT sensor coupler 1.
• Remove the rear intake pipe and thermostat assembly.
(!3-13)

INSPECTION
• Check the ECT sensor by testing it at the bench as shown in
the figure. Connect the ECT sensor 1 to a circuit tester and
place it in the oil 2 contained in a pan, which is placed on a
stove.
• Heat the oil to raise its temperature slowly and read the col-
umn thermometer 3 and the ohmmeter.
• If the ECT sensor ohmic value does not change in the propor-
tion indicated, replace it with a new one.
" Temperature sensor specification
" Cooling fan operating temperature:
Standard (OFF→ON): Approx. 105 °C (221 °F)
(ON→OFF): Approx. 100 °C (212 °F)
NOTE:
As coolant temperature rises, the cooling fan operates for 5 sec-
onds when the temperature arrives each at 50 – 70 °C (122 –
158 °F), 70 – 90 °C (158 – 194 °F) and 90 – 110 °C (194 –
230 °F)/above 4 000 r/min.
Temperature Standard resistance
20 °C (68 °F) Approx. 2.45 kΩ
50 °C (122 °F) Approx. 0.811 kΩ
80 °C (176 °F) Approx. 0.318 kΩ
