is satisfied the failsafe device switches q 1 on via r 4 to activate the relay k 1 preferably using a pulse width modulation u201c pwm u201d switching scheme based on elapsed time u201c programmable modulated throttle control technology u201d to ensure that the tps signal does not trigger in the ecm a vehicle u201c limp mode u201d or such pwm switching of the relay k 1 may be based on amplitude of the detected tps signal such as u201c switch off u201d in response to receipt of a tps signal passing approximately 0 5 vdc and u201c switch on u201d if such signal again exceeds approximately 1 4 vdc u201c adaptive firmware throttle control u201d in other embodiments suitable voltages may be used that correspond to the applicable vehicle of interest preferably both switching modes may be realized in the failsafe device the adaptive firmware throttle control is software loaded onto the processor u 2 to automatically adjust timing for periodic interrupt of the duty cycle of the etmc circuit help the driver regain control of the vehicle the programmable modulated throttle control is a set of values such as timing for the periodic interrupt of the etcm circuit that are pre programmed into the module u 2 both the hardware and software of the failsafe device when activated will provide filtering of the tps signals to reduce false triggering such as through r 1 c 1 r 8 c 10 r 5 r 7 c 8 and software detection in module u 2.
