Section 08 ELECTRICAL SYSTEM Subsection 05 (INSTRUMENTS AND ACCESSORIES)
When there is enough oil inside the oil tank (and therefore in the sensor reservoir), the sensor detects the liquid and the light DOES NOT turn onWhen the oil level goes at critical LOW level inside the oil tank (and therefore in sensor reservoir), the sensor detects the absence of liquid and the light TURNS ONTo check the oil sensor, unplug its connector and pull sensor out of oil tankUsing multimeter, check the continuity between the BLUE and BLUEBLACK terminalsWhen sensor is out of oil tank and its reservoir is empty, resistance must be infinite (open circuit)NOTE: Wait about 15-20 seconds before taking any reading to give the oil enough time to flow out or inside sensor reservoirSoak sensor in oil so that its reservoir fills upMaximum resistance should be approximately (closed circuit)TEST CONDITION Sensor OUT of oil Sensor soaked IN oil READING () (open circuit) max(closed circuit)
