if there is an oil level sensor on it that would be located on either side of the oil pan near where it meets the engine block. This might also be a coolant sensor level warning light which in that case there would be a sensor on the side of the radiator or possibly in the reservoir.
i looked through my material i have on that truck but it does not show the dash light indicators , i believe that would be shown in the operators manual which i do not have. But there are only to fluid levels it would be indicating if it has an engine block pictogram in it, that would be oil level or coolant.
