HEATED OXYGEN SENSOR
(SENSOR-1 AND SENSOR-2)
OXYGEN SENSOR HEATER INSPECTION
1) Disconnect sensor coupler.
2) Using ohmmeter, measure resistance between terminals "V
and "GND" of sensor coupler.
NOTE :
Temperature of sensor affects resistance value largely.
Make sure that sensor heater is at correct temperature.
Resistance of oxygen sensor heater:
11.7 – 15.6 W at 20_C, 68_F
If found faulty, replace oxygen sensor.
3) Connect sensor coupler 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.
1) Disconnect negative cable from battery.
2) For sensor-2, remove console box.
3) Disconnect coupler of heated oxygen sensor and release its
wire harness from clamps.
4) For sensor-2, Hoist vehicle.
5) For sensor-1, remove exhaust manifold cover.
6) Remove heated oxygen sensor from exhaust manifold or ex-
haust pipe.
INSTALLATION
Reverse removal procedure noting the following.
D Tighten heated oxygen sensor to specified torque.
Tightening Torque for heated oxygen sensor
(a): 45 N·m (4.5 kg-m, 32.5 lb-ft)
D Connect coupler of heated oxygen sensor and clamp wire har-
ness securely.
D After installing heated oxygen sensor, start engine and check
that no exhaust gas leakage exists.
