INSPECTION
INSPECT HEATER RESISTANCE OF A/F SENSORS
(Bank 1 sensor 1, Bank 2 Sensor 1)
(a) Disconnect the A/F sensor connector.
(b) Using an ohmmeter measure the resistance between ter-
minals +B and HT.
Resistance:
At 20°C (68°F)0.8 - 1.4 W
At 800°C (1,472°F)1.8 - 3.2 W
If the resistance is not as specified, replace the sensor.
Torque: 44 N´m (450 kgf´cm, 32 ft´lbf)
(c) Reconnect the A/F sensor connector.

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
1. DRAIN ENGINE COOLANT
2. REMOVE ECT SENSOR
(a) Disconnect the ECT sensor connector.
(b) Using a 19 mm deep socket wrench, remove the ECT
sensor and gasket.
3. INSPECT ECT SENSOR
Using an ohmmeter, measure the resistance between the ter-
minals.
Resistance: Refer to the graph
If the resistance is not as specified, replace the ECT sensor.
4. REINSTALL ECT SENSOR
(a) Install a new gasket to the ECT sensor.
(b) Using a 19 mm deep socket, install the ECT sensor.
Torque: 20 N´m (200 kgf´cm, 14 ft´lbf)
(c) Connect the ECT sensor connector.
5. REFILL WITH ENGINE COOLANT

Heated Oxygen Sensor (Bank 1 Sensor 2)
Before installing the heated oxygen sensor,
twist the sensor wire counterclockwise
3 and 1/2 turns. HINT:
After installing the heated oxygen sensor,
check that the sensor wire is not twisted,
if it is twisted,remove the heated oxygen
sensor and reinstall it. The Location of Fuel Tank Cushion
