Sensor Test
Remove sensor from floorboard. Wrap a thermometer and sensor with aluminum foil and place in an oil bath. See Fig 1. Connect test lamp and battery to sensor coupler terminals. Gradually heat oil. Test lamp should come on when temperature in aluminum foil reached 284-320°F (140-160°C). If sensor does not operate within specifications, replace sensor assembly.
NOTE:
Do not heat oil to more than 392°F (200°C).
