ABSTRACT:
Rather than having the two throttle position sensors connected directly to a common D.C. power supply, isoation circuits are connected between each sensor and the power supply so that a short in one sensor will be indicated to the ECU without adversely affecting the signal from the other sensor. The isolation circuits are simple RC circuits.
