Abstract
A method and system of throttle calibration control is presented that includes a TPS designed to provide an output indicative of throttle plate position when the throttle plate is opened and provide an output of throttle actuator position when the throttle plate is closed. The TPS output is received by an ECU to control subsequent engine operation. When an input is received from the TPS indicating that the throttle actuator is within a pre-set idle throttle position range and below an idle position benchmark, the ECU automatically reestablishes present and subsequent engine operation.
