DTC 1371 is a problem with the Low-resolution pulse than is generated in the Opti. The Opti also generates a High-Resolution pulse and both pulses are sent to the PCM.
The problem could either be the Opti, or the wiring harness between the Opti and PCM. Here is the wiring diagram for the 95-97s. The optical module (within the Opti) can fail, or maybe there is debris (crap) on the Opti shutter/strobe wheel.
