ECT SENSOR INSPECTION
• Remove the ECT sensor. (5-77)
• 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.
