1988 Chevrolet Baretta, CKP Sensor, Waveform
Here is a good crank and reference relationship. This is a good set up for testing module function. My experience is that a good crank and bad reference = bad module, assuming powers and grounds are ok. This reference signal is produced by the module alone.
