CPS generates an AC voltage signal. Has nothing to do with 5v reference voltage at other sensors.

X2. Renix didn't use a reference voltage like the HO senor. Stick a meter on the output of the crank sensor and look for a/c voltage while cranking. It won't be very high, and the number depends somewhat on your meter as it's not a sine wave.
