Really can't see the alternator diode circuit being anyway related to the cyl sensor. It's just a simple 2 wire circuit between disturber and ecu. Ecu and ecu terminal problems aren't all that common. More than likely the sensor itself.

Trying hard to remember...but i'm thinking all the sensors in the distributer ground through the ecm. One of the main grounds for the ecm is on the thermostat housing. But if that ground was an issue, i think you'd see more engine light problems related to the output side of things...ie: injector, eacv valve
