6E2-40 ENGINE AND EMISSION CONTROL SYSTEM (H25 ENGINE)
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, replace ECT sensor.
INSTALLATION
Reverse removal procedure noting the following.
• 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.
Heated oxygen sensor (sensor 1)
REMOVAL
1) Disconnect negative cable from battery.
2) Disconnect coupler of oxygen sensor(s).
[A] : Resistance [B] : Temperature [C] : ( ) for reference
WARNING:
To avoid danger of being burned, do not touch exhaust
system when system is hot. Oxygen sensor removal
should be performed when system is cool.
