6E2-36 ENGINE AND EMISSION CONTROL SYSTEM (SEQUENTIAL MULTIPORT FUEL INJECTION FOR H27 ENGINE)
Engine coolant temperature sensor (ECT sensor)
REMOVAL
1) Disconnect negative (–) cable from battery.
2) Drain cooling system.
3) Disconnect coupler from ECT sensor (1).
4) Remove ECT sensor from water outlet cap (2).
INSPECTION
Immerse temperature sensing part of ECT sensor in water and
measure resistance between sensor terminals while heating
water gradually.
If measured resistance doesn’t shown such characteristic as
shown in the figure, replace ECT sensor.
INSTALLATION
Reverse removal procedure noting the followings.
• Clean mating surfaces of sensor and water outlet cap (1).
• Use new O-ring.
• Tighten ECT sensor to specified torque.
Tightening torque
ECT sensor (a) : 15 N·m (1.5 kg-m, 11.0 lb-ft)
• Connect coupler to sensor securely.
• Refill cooling system.
