Voltage Signal: Description and Operation

PURPOSE

Supplies Powertrain Control Module (PCM), with current charging system voltage.

OPERATION

If the PCM senses low battery voltage:

- PCM increases injector pulse width to compensate for low voltage.

- PCM increases generator field voltage.

If the PCM senses high battery voltage:

- PCM decreases injector pulse width to compensate for high voltage.

- PCM decreases generator field voltage.
