7. INSPECT AIR FUEL RATIO SENSOR HEATER RELAY
(a) Inspect the resistance.
(1) Using an ohmmeter, measure the resistance be-
tween the terminals.
Standard:
Tester ConnectionSpecified Condition
3 - 510 kW or higher
3 - 5Below 1W
(Apply battery voltage to terminals 1 and 2
If the result is not as specified, replace the air fuel ratio sensor
heater relay.

NOTICE:
Check around the quick connector for dirt or mud be-
fore this operation. Remove the dirt if necessary.
Be careful of mud because the quick connector has
an O-ring which seals the pipe and quick connector
that can be contaminated.
Do not use any tools in this operation.
Do not bend or twist the nylon tube. Protect the quick
connector by covering it with a vinyl or plastic bag.
When the pipe and quick connector are stuck, push
and pull the quick connector to release. Pull the quick
connector carefully.
