Throttle Full Close Switch: Description and Operation

PURPOSE

When the idle switch is closed, the IGNITION ECM does not recognize engine load (MAP sensor) input and chooses the idle portion of the ignition
strategy.  Timing during closed throttle operation is programmed separately for idle and deceleration.  Modifications to basic timing choices are
calculated according to engine speed and coolant temperature inputs.

OPERATION

This is a closed or open switch.  It is closed when throttle is closed and open at all other throttle positions.
