aThe decelerator position sensor provides a pulse width modulated signal that varies with the position of the decelerator. The Electronic Control Module (ECM) translates the signal into a percentage that is displayed as "Decelerator Position". The range for "Decelerator Position" is 0 to 100 perce...
A pulse-width modulated DC to DC converter is enabled to operate into short circuits and limit the current output by having the capability of operating at zero percent duty cycle. The regulation feedback loop utilizes a light-emitting diode and phototransistor optical arrangement to permit isolation...
