3. ECT (Engine Coolant Temperature) SENSOR
The sensor resistance decreases as the coolant tem-
perature increases as shown on the right table.
1) Disconnect the 2P connector from the thermo sensor
and measure the resistance between the sensor ter-
minals at the room temperature.
Standard resistance: 1
-
5 k!2
2) Connect the 2P connector and start the engine and
warm up the engine to normal operating temperature.
3) Stop the engine, and disconnect the 2P connector
and measure the resistance.
Standard resistance: 200
-
400 R
ECT sensor installation/removal is almost the
same as installation/removal of the sermo switch.
