It originally came with Freon (R12). Unless it has been converted then it will still contains R12. I suggest you have it converted to R134a, as Freon is so very expensive and hard to find.
R134a
The 2002 ford Ranger uses type R134 Freon. The Freon is added in the low pressure port of the ac system.

OEM refrigerant which came installed in 1993 was Freon R12. I suggest you convert it to R134a if it has not already been converted. R12 is far to expensive.

Being a 1992 model year it would be R-12 ( unless it has already been converted to use refrigerant R134a )

Some of the 1992 Rangers had the camshaft position sensor on top of the engine in the same hole where the distributor used to be. Some Ranger engines did not use a camshaft sensor at all.
