ABSTRACT:
An apparatus for correcting a throttle valve position signal indicative of a sensed position of a throttle valve provided for controlling the amount of air permitted to enter engine cylinders. The sensed throttle valve position value sensed at an engine idling condition is set for an idle position value. A first error of the idle position value from a first reference value corresponding to a throttle valve idle position designed for an air conditioning unit being not operating. The first error is used to correct a sensed throttle valve position when the air conditioning unit is not operating. A second error of the idle position value from a second reference value corresponding to a throttle valve idle position desired for the air conditioning unit being operating. The second error is used to correct a sensed throttle valve position when the air conditioning unit is operating.
