INSPECTION
1. REMOVE RELAY BOX COVER
2. REMOVE A/F SENSOR HEATER RELAY (Marking: A/F
HTR)
3. INSPECT A/F SENSOR HEATER RELAY CONTINUITY
(a) Using an ohmmeter, check that there is continuity be-
tween terminals 1 and 2.
If there is no continuity, replace the relay.
(b) Check that there is no continuity between terminals 3 and
5.
If there is continuity, replace the relay.
4. INSPECT A/F SENSOR HEATER RELAY OPERATION
(a) Apply battery voltage across terminals 1 and 2.
(b) Using an ohmmeter, check that there is continuity be-
tween terminals 3 and 5.
If there is no continuity, replace the relay.
5. REINSTALL A/F SENSOR HEATER RELAY
6. REINSTALL RELAY BOX COVER

INSPECTION
INSPECT HEATER RESISTANCE OF HEATED OXYGEN
SENSOR (Bank 1 Sensor 2)
(a) Remove the passenger's seat.
(b) Disconnect the oxygen sensor connector.
(c) Using an ohmmeter, measure the resistance between the
terminals +B and HT.
Resistance:
At 20°C (68°F)11 - 16 W
At 800°C (1,472°F)23 - 32 W
If the resistance is not as specified, replace the sensor.
Torque: 44 N´m (450 kgf´cm, 32 ft´lbf)
(d) Reconnect the oxygen sensor connector.
(e) Reinstall the passenger's seat.
