An apparatus for and method of controlling multiple electronically controlled components (101) utilizes a controller (103) that controls one of the components (101A). A control interface (211) replicates the control signal (201) generated by the controller (103) for each additional component (101B through 101E), such that the replicated signal bears significant resemblance to the original control signal with respect to current, voltage, and pulse width. The replicated signals are provided to the additional components (101B through 101E) at substantially the same time as the control signal (201) is provided to the first component (101A).

1. A system comprising:a control signal operably coupled to a first electronically controlled component of N+1 electronically controlled components, where N is an integer greater than or equal to 1; N signal repeaters, each having an input sourced by the control signal and each generating a repeated control signal; N regulators, each having an output, each having an input sourced by one of the N repeated control signals, and each connectable in parallel with one of N electronically controlled components of the N+1 electronically controlled components, wherein the first electronically controlled component is not one of the N electronically controlled components; a power source, operably coupled to each output of the N regulators, and capable of providing a predetermined amount of current to each of the N electronically controlled components; wherein the predetermined amount of current is provided to each of the N electronically controlled components at substantially the same time that the control signal is provided to the first electronically controlled component. 2. The system of claim 1, wherein each of the electronically controlled components is a valve, wherein the control signal is a pulse width modulated signal having an amplitude and a width, wherein the amplitude of the control signal represents the predetermined amount of current, and wherein the width of the control signal represents how open the valve is.3. The system of claim 1, wherein the control signal provides a substantially fixed voltage at a substantially fixed current for a time period determined by an engine control module in an internal combustion engine.4. The system of claim 1, wherein the N+1 electronically controlled components have a serial interface with each other.5. The system of claim 4, wherein the serial interface is physical.6. The system of claim 1, wherein the N+1 electronically controlled components have a parallel interface with each other.7. The system of claim 6, wherein the parallel interface is physical.8. The system of claim 1, wherein each of the N signal repeaters comprises a Darlington transistor pair.9. The system of claim 1, wherein each of the N regulators comprises a Zener diode.10. The system of claim 1, wherein the electronically controlled components are each exhaust gas recirculation valves.11. A method comprising the steps of:providing, from a first source and to a first electronically controlled component, a control signal having a predetermined current at a predetermined voltage; generating, from a second source, current sufficient to supply the predetermined current at the predetermined voltage to N additional electronically controlled components, where N is an integer greater than or equal to 1; replicating the control signal, thereby generating N replicated control signals, one for each of the N additional electronically controlled components, such that the predetermined current at the predetermined voltage is applied as one of the N replicated controls signals to each of the N additional electronically controlled components at substantially the same time that the control signal is provided to the first electronically controlled component. 12. The method of claim 11, wherein each of the electronically controlled components is a valve, wherein the control signal is a pulse width modulated signal having an amplitude and a width, wherein the amplitude of the control signal represents the predetermined amount of current, and wherein the width of the control signal represents how open the valve is.13. The method of claim 11, wherein the pulse width of the control signal is determined by an engine control module in an internal combustion engine.14. The method of claim 11, further comprising the step of providing a serial interface between the N+1 electronically controlled components.15. The method of claim 14, wherein the serial interface is physical.16. The method of claim 11, further comprising the step of providing a parallel interface between the N+1 electronically controlled components.17. The method of claim 16, wherein the parallel interface is physical.18. The method of claim 11, further comprising the step of activating at least one of the N additional electronically controlled components.19. The method of claim 11, further comprising the step of deactivating at least one of the N additional electronically controlled components.
