You can literally test it in less time than it takes to boil coffee water ;
AC voltage CPS test; Small clips on the meter leads really helps.
Unplug the connector at the back of the manifold with wires going down to the bell-housing/cps.
Probe the two wires to the cps with the meter set on AC volts. (a 200 scale on mine).
Crank the engine and note the voltage. (jump it if your battery is low)
Mine somehow works with only .3 my wiring/grounds must be pretty spiffy. .5 seems to be a good mark. One article talked of .5 to .8. **Update, it soon failed. I installed Napa #css980 in my 90.** @.4 now.
If you click on my Signature Cruiser's Renix stuff it right on-top with more...

Hmmmmm I'll check my EGR, Ive had similar issues on a GM car in the past.
I did plugs, wires, cap/rotor on the jeep roughly 5k miles ago.
