Town & Country Van V6-229 3.8L VIN L MFI (1995)
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.
