With the ignition on, check that the voltage
value between pins 3 and 5 of the potentiometer 2 various continuously
as the degree of aperture of the throttle valve varies.The reference values are about 0.7 V with
the accelerator pedal released (throttle closed) and about 4.3 V
with the accelerator pedal fully depressed (throttle fully open).With the ignition on, check that the voltage
