METERS AND GAUGES - Service Adjustment Procedures
ENGINE COOLANT TEMPERATURE GAUGE SIMPLE TEST NI8moO.
(1) Remove connector from engine coolant temperature
gauge unit in engine compartment.
(2) Ground harness side connector via test light.
(3) Turn ON ignition key.
(4) Check that test light flashes and gauge needle moves.
(5) If test light flashes hut the gauge needle does not move,
replace engine coolant temperature gauge.
If test light does not flash (and gauge needle does not
move), check fuse for broken wire, or resistance between
gauge terminals (see pages 8-174.). or break in harness.
ENGINE COOLANT TEMPERATURE GAUGE UNIT INSPECTION WIKO
Refer to GROUP 7 - Engine Coolant Temperature Gauge
Unit.
FOIL PRESSURE GAUGE SIMPLE TEST
(I) Disconnect the wiring connector from the oil preszi
gauge unit inside the engine compartment.
(2) Ground the connector at the harness through a test light.
(3) Turn the ignition key to the ON position.
(4) Check to be sure that the test light illuminates steadily
and the indicator of the oil pressure gauge moves.
(5) If both the test light and gauge operate, the circuit to the
gauge unit is normal and the gauge unit itself is faulty. If
the test light flashes but the gauge does not operate, the
gauge is faulty.
If neither the test light nor the gauge operates, the oil
pressure gauge circuit is faulty.
