6E-30 ENGINE AND EMISSION CONTROL SYSTEM
1. Viewed from terminal side
INSTALLATION
Reverse removal procedure noting the following:
D Clean mating surfaces of ECT sensor (1) and intake manifold.
D Replace O-ring with new one.
D Tighten ECT sensor (1) to specified torque.
Tightening Torque
.
(a): 15 N m (1.5 kg-m, 11.5 lb-ft)
D Connect connector to ECT sensor (1) securely.
D Refill coolant referring to Section 6B.
HEATED OXYGEN SENSOR (Sensor-1 and Sensor-2)
(IF EQUIPPED)
OXYGEN SENSOR HEATER INSPECTION
1) Disconnect sensor connector.
2) Using ohmmeter, measure resistance between terminals "V
and "GND" of sensor connector.
NOTE :
Temperature of sensor affects resistance value largely.
Make sure that sensor heater is at correct temperature.
Resistance of oxygen sensor heater :
5.0 – 6.4 W at 20_C, 68_F for HO2S-1
11.7 – 14.3 W at 20_C, 68_F for HO2S-2
If found faulty, replace oxygen sensor.
3) Connect sensor connector securely.
REMOVAL
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.
