Daytona IROC R/T L4-135 2213cc 2.2L DOHC Turbo VIN A FI (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.
