I am not sure I understand your question about a CPS code on the 8 module. If you are referring to pin 8, I only have readouts on pins 3,6,7 & 14. Except for the push button and LED, all other pins are blank.

Ok .. Pin 8 would be Ign module on later models w/16 pin DM
So, yours will be Pin 3.
Like I said , I just can't find any info on that Cal version , mostly b/c it was early Cal w/16 pin...so I do not know what they have . I did find codes for that chassis, but Not Cal. Emmssions.
But I do have TN codes on Fed versions and you can ohm the sensors from the end of the cable and see if your WIS gives you those values..you can also flex the cable/harness and watch the meter for intermittant readings, indicating poorconnection/wiring.
The AllData just has "Check speed sensor wiring" as test for TN code. They also have a scope pattern test at ECU, but that does not help you. [ unless you have a DSO?]
I will do some more searching, but that is an early Cal car and info is hard to find...Your WIS would prob have more info than my AllData does.
