Abstract
A system for automate correction of characteristics of a throttle position sensor includes the throttle position sensor, a memory, a comparator and a correction device. The throttle position sensor detects a voltage corresponding to a throttle position. The memory stores first and second voltages which correspond to respective 0% and 100% throttle position set points. The comparator performs a comparison between the voltage detected by the throttle position sensor and both the first and second voltages stored in the memory. The correction device expands by a small value the range between both the first and second voltages stored in the memory when the throttle position voltage has been determined to be greater or smaller than both the first and second voltages, corrects the first and second voltages in the memory by using the upper and lower limit values of the thus expanded range as new first and second voltages for the 0% and 100% throttle position set points, and then stores the corrected first and second voltages in the memory. A throttle position signal is hence determined based on the corrected first and second voltages, which correspond to 0% and 100% throttle position set points, stored in the memory.
