where is the cam sensor located on my 1992 Geo Storm I have a 1.6 liter engine

I have a 1992 Geo storm it cranks but does not start, i have tested all the sensors except the cam sensor, and I have replaced the main coil, still i get no spark from the coil. the distributor is functioning, all my fuses are good and connections to the battery are fine. where is the cam sensor located it is not mentioned in the Haynes manual or is it called something else?
