Shadow L4-153 2.5L SOHC VIN B (1993)
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.
