COOLING AND LUBRICATION SYSTEM
ECT Sensor
Removal
● Remove the left side cover.
● Disconnect the ECT sensor coupler [1].
● Place a rag under the ECT sensor and remove the ECT sensor.
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 water [2] contained in a pan, which is placed on a stove.
● Heat the water to raise its temperature slowly and read the
column thermometer [3] and the ohmmeter.
● If the ECT sensor ohmic value does not change in the proportion
indicated, replace it with a new one.
● If the resistance is noted to show infinity or too much different
resistance value, replace the ECT sensor with a new one.
Temperature Sensor Specification
Temperature Standard Resistance
60 (140 ) Approx. 0.704 k Ω
90 (194 ) Approx. 0.261 k Ω
120 (248 ) Approx. 0.111 k Ω
CAUTION
○
Take special care when handling the ECT sensor. It may cause
damage if it gets a sharp impact.
○
Do not contact the ECT sensor and the column
thermometer with a pan
